Common things science still can't explain.

Fingerprints.

That's right, the first entry on this list is something that we all have access to at our fingertips.

And that's because it literally is our fingertips.

Or more specifically, our fingerprints.

I think we all know that everybody has fingerprints, and beyond that we all have unique fingerprints.

And we also know that the fingerprints your cousin leaves on the glass in every device is really annoying.

But beyond the existence and uniqueness of fingerprints, what is there not to know?

And the answer is, well, the purpose of fingerprints to begin with.

Interestingly, we actually know a lot more about the origin of fingerprints rather than the purpose of fingerprints.

Obviously, in modern times, the fingerprint is an extremely useful tool, most commonly used in forensics investigations and also while opening your iPhone 6.

And while those are definitely interesting use cases for our fingertips,

the human body didn't spend hundreds of thousands of years just to develop fingerprints for biometric data purposes.

And like the title of this video suggests, the true purpose of fingerprints is still relatively unknown, although there is two primary theories.

But before we get into those, I want to actually explain quickly how we even get fingerprints in the first place.

When you were a little fetus in your mother's womb, your fingerprints surprisingly were one of the earliest defining features developed on your entire body.

Obviously after your arms and hands.

And these unique designs are carved into your fingertips through the pressure of amniotic fluid in your mother's womb.

The pressure of this fluid, coupled with the growth rate of your fingers and other unique factors,

are what cause the consistently unique design of your fingerprint.

Which is really interesting.

Your fingerprint isn't genetic whatsoever and identical twins do not share the same fingerprint.

And that same fingerprint you develop early on in your mother's womb, you will keep until the day you die.

Which is also super interesting.

But not quite as interesting as the two running theories on why we even have fingerprints in the first place.

The first theory is that we have fingerprints to improve grip.

This theory states that the grooves on your finger act like tread on a tyrant

and are intended to allow you to grip, hold, and throw things easier.

And this theory makes sense and is definitely valid, and there is even evidence to support this claim.

And the other primary theory for why we have fingerprints is actually for tactile reasons.

This theory states that we have fingerprints to help us sense vibrations and to feel textures more fully and effectively, enhancing our sense of touch.

And once again, there is evidence to support this claim as well.

And while both of these theories are valid and seem extremely logical, and both share evidence that can back up their claims,

there's not yet any concrete evidence proving a specific purpose for your fingerprint.

Alzheimer's.

If you're watching this video, it's likely that you don't have Alzheimer's.

But if you do have Alzheimer's, then it's likely you've seen this video before and just don't remember it.

Regardless, Alzheimer's is unfortunately more common than you think, and most people watching this video have likely experienced Alzheimer's in one way or another.

The reality of Alzheimer's is horrifying and truly upsetting, and that is coming from a bystander's perspective.

I can only imagine the experience of somebody dealing with the trauma firsthand.

But for how common Alzheimer's is and how much awareness is being brought to it these days

There are still so many things that are just completely unknown

when it comes to Alzheimer's I think it's important to note first

and foremost that Alzheimer's and dementia are not the same thing

And while they are related, they're not interchangeable

And on top of that, Alzheimer's is not a natural part of human progression

While cognitive decline is normal as you age, the rapid and detrimental decline that happens with Alzheimer's is nowhere near normal

And for that reason, it's not called old timers, it's called Alzheimer's And I'm not even making this up,

when I was a kid I swear to god I thought it was called old timers because old people got it.

And I'm just really hoping I'm not the only one who thought that.

But tossing my own personal cognitive decline to the side, what is the cause of Alzheimer's?

And the answer is complicated.

As of today, the most common theory is that a combination of age -related brain changes,

genetic factors, and environmental and lifestyle influences play a role in the development of Alzheimer's.

Although the exact biological root cause of the disease is still unknown.

Basically meaning that there's a lot of ways you could potentially get Alzheimer's, like smoking all your life,

or working shift work and having a bad circadian rhythm, or potentially being genetically predisposed.

And while all of these may be a contributing factor, there's not yet one underlying causality.

But with that being said, as of now there are still two primary biomarkers that are believed to be tied to Alzheimer's.

The first is amyloid beta plaques.

And what amyloid beta plaques are are actually buildup of amyloid beta, which is a part of amyloid precursor protein.

What does amyloid precursor protein do in the brain, you might ask?

Science doesn't know that either.

But it's believed, but not proven, to have something to do with brain development.

Regardless, patients with Alzheimer's will see this amyloid beta protein not being properly absorbed in the brain, causing it to clump together and create plaques,

causing the eventual rapid decline in cognition.

And the reason for this is

because these amyloid plaques are actually toxic to the brain and cause cell death within your brain, which is why, typically in Alzheimer's patients,

you will see brains with massive holes in them which honestly just adds a whole new layer of disturbing to this disease.

But even the role of these amyloid plaques are debated, because recently there have been medications specifically designed to destroy these amyloid plaques in the brain,

and unfortunately these tests have not bred positive results,

which has caused scientists to question whether or not this plaque is the root cause or simply a byproduct of a deeper, more unknown root cause.

Oh yeah, and the other biomarker associated with Alzheimer's is another protein used in the brain known as tau.

And similar to the other protein we just discussed,

for patients with Alzheimer's, the tau in the brain is not used properly and is not absorbed and becomes tangled and creates,

once again, toxic clumps in the brain, causing cell death and cognitive decline.

So yeah, although it may seem like we know quite a bit about Alzheimer's, there is

so much more we have to learn before we are able to make any sort of meaningful development in prevention

and hopefully cure animal migration.

Migration by far is one of the most underrated animal superpowers.

Like seriously, just imagine being able to be anywhere and being able to then navigate to a specific location, usually across an entire continent, just because.

Migration is a necessary survival mechanism for countless species of animals.

And it's actually really well understood why certain species migrate.

The reason depends on the species, but the most common reasons for migration are either to feed, breed, or to escape harsh climates,

like cold winters or hot summers.

And that is simple and something we truly understand.

But it's not the why of migration that's unexplained.

It's the how.

Like, just think about it.

How do these animals know consistently year over year not only when to go, but exactly where to go?

You could give a lot of people today a car and a physical roadmap,

and they would still get lost trying to go to a specific location.

But if you just tell a butterfly that they've got to fly 2 ,000 miles to get laid,

they're already gone before you could even tell them what direction to go.

And it's so amazing, in fact, that we still, to this day, don't understand how animals know where to migrate.

Or more specifically, how to get to their point of migration.

Birds, whales, sea turtles, and even insects are all examples of animals that migrate.

And for most of them, the places they go to migrate are rather specific.

Although, where they may be living in their off -season is kind of random.

100

However, every year, they consistently know, no matter where they are, where to go.

101

And that phenomenon is truly amazing.

102

And while in 2025 humans have GPS, Google Maps, and now self -driving cars, we still get lost a lot.

103

And this thought process has led researchers to believe that animals have something that we don't.

104

And recent studies have shown that this could potentially be true.

105

And one example that research has recently shown was that some species of birds, specifically pigeons, were able to sense the Earth's magnetic field.

106

And first of all, I'm just curious how they even found this out in the first place.

107

Like, I can only imagine two scientists just sitting a pigeon down in the lab, looking at him, and just asking, do you feel anything?

108

With the pigeon only to respond, North.

109

And this is a skill known as magnetorception.

110

And I'll be honest, I wish I had magnetorception, because that sounds cool as hell.

111

Regardless, with the discovery of pigeons being able to sense the Earth's literal magnetic field, this one answer has led to many more questions.

112

Like, how many other animals share this ability?

113

And what other abilities exist in the animal kingdom that we don't even know about yet?

114

And for animals with this ability, how do they even use this knowledge of the magnetic field to navigate properly and accurately?

115

It's truly amazing.

116

And I guess the human equivalent of this would be trying to understand how your broke,

117

drunken uncle always makes his way down to Florida every time winter comes in Michigan.

118

Like, your drunken uncle could be anywhere in the Northern Hemisphere for seven months out of the year.

119

But somehow, as soon as it just gets a little chilly, he teleports to Florida.

120

But nobody knows how he got there.

121

It's just like that.

122

The placebo effect.

123

The placebo effect is a staple in modern medicine testing because of how prevalent this effect is.

124

To summarize the placebo effect, it's essentially just suggestibility.

125

It's your mind believing something to be true and your body kind of following suit.

126

And while that's a bit of an oversimplification, the results of the placebo effect are amazing, but also mysterious.

127

The placebo effect is so strong and so common that any time a new drug is tested to bring to market,

128

They literally have to test the new drug that's being proposed against a placebo to make sure

129

that the drug is actually effective and not just seeming effective due to the placebo effect.

130

For example, let's just say you're trying to develop a new drug that helps people with stomach pain.

131

Now, let's say for a study, you find 100 people that have frequent stomach pain.

132

You divide this group into two smaller groups, a treatment group and a placebo group.

133

All 50 people in the treatment group receive the actual medication you're testing.

134

And all 50 people in the placebo group receive, well, a sugar pill, a placebo, a drug that does nothing.

135

It's not even a drug.

136

Now here's the kicker.

137

Everybody in this test is under the assumption that they are actually taking the active medicine.

138

And after consistently taking the medicine for, let's say, a week, you have to review the results.

139

And this is where the placebo effect actually comes into play.

140

Because let's say after a week of taking the placebo,

141

25 out of the 50 people in the placebo group say that they noticed less stomach pain.

142

That is kind of the benchmark that the treatment group has to surpass.

143

Meaning that if the treatment group also reports a 25 % decrease in stomach pain, it's actually not proven effective.

144

In that case, it's about as effective as a placebo.

145

For this medication for stomach pain to be proven effective,

146

there has to be more people in the treatment group that feel better than people in the placebo group.

147

And this oversimplified, poorly explained explanation is what's known as a double -blind placebo study,

148

and it's kind of the gold standard for eliminating bias when it comes to testing brand new medications.

149

Now here's the thing, with all of this being said, how does the placebo effect even work?

150

And the answer is, we actually don't know that much about it researchers

151

that have been studying the placebo effect from a psychological and neurological angle,

152

both kind of believe that this effect is linked to a brain's release of endorphins

153

and other chemicals in the anticipation of a positive effect, essentially meaning that because your body is expecting to feel better,

154

it already kind of feels better in advance.

155

But this isn't proven, and is really only a going theory.

156

And despite there being literally decades of study on the placebo effect up until this point, the exact mechanisms behind the placebo effect are completely unknown,

157

making one of the staples of modern medicine testing, an effective and life -saving mystery.

158

The Twilight Zone.

159

No, not that Twilight Zone.

160

This Twilight Zone.

161

Home of this, this, this, and this.

162

The Twilight Zone is located 200 to 1000 meters below the ocean's surface.

163

And it's known as the Twilight Zone because it is a region underwater where sunlight barely penetrates.

164

It's too dark for any sort of photosynthesis, but it's not quite pitch black yet.

165

And it's this unique region that is one of the least explored habitats on all of planet Earth.

166

One notable resident of this area is the lanternfish, which is pretty cool, but also completely insane.

167

It kind of goes to show how weird this area is.

168

Like we all know that jellyfish are like just weird creatures, but deep sea jellyfish are on a whole nother level.

169

Like I was just watching a documentary where some jellyfish literally asexually reproduce

170

and basically just spawn new jellyfish kind of like plants.

171

And jellyfish as a whole are just kind of crazy entities.

172

Like they're alive, but they're not.

173

It's just so wild.

174

But that's not the mystery here.

175

It has nothing to do with jellyfish per se.

176

The Twilight Zone, like I mentioned, is one of the least explored areas.

177

And for good reason, too.

178

The pressure that deep underwater is immense.

179

And coupling that pressure with the sheer darkness and travel time

180

and specialized equipment required to even navigate through this area makes any sort of Twilight Zone exploration extremely expensive and difficult.

181

And because there's not really a major financial incentive to explore the Twilight Zone, research is definitely a bit slow.

182

But not only is the Twilight Zone extremely harsh to get to and be in, but it's also extremely vast,

183

making exploring and documenting it nearly impossible fully.

184

And because the Twilight Zone is so massive, it's actually speculated

185

that there may be more fish in the Twilight Zone alone than all other fish on the entire Earth combined.

186

And while this is kind of a fruitless thought experiment, at this point it's also extremely possible.

187

But not only is it possible, it's a scary thought, because the fish that live in the Twilight Zone are completely weird looking,

188

and probably the closest thing we have to aliens at this time.

189

Like these fish are literally creating their own light, which is kind of dope.

190

I don't know, I think bioluminescence is just cool to begin with, but I also like to think that fish just got

191

so fed up of being in the dark that they literally created their own organic light.

192

But it's not just seeing cool fish that light up that makes the Twilight Zone interesting.

193

It's also the impact that the Twilight Zone has on the Earth's climate, because the Twilight Zone is a massive ecosystem.

194

And ocean and marine ecosystems specifically play a major role when it comes to carbon storage, which obviously has a direct impact on the Earth's climate.

195

Which definitely gives merit to wanting to explore the Twilight Zone more.

196

But yeah, that's kind of all there is to say about it.

197

The Twilight Zone is one of the most common ecosystems in all of the world, technically speaking.

198

Although it's one of the ecosystems we know the least about.

199

And maybe that's for the better.

200

Ball lightning.

201

Admittedly, ball lightning isn't all that common.

202

But lightning is relatively common.

203

And I think most of us have heard about ball lightning, and honestly, I just thought it was cool and wanted to discuss this interesting phenomenon.

204

Ball lightning sightings have gone back all the way to the 1600s, and continue to be reported today.

205

It's interesting because even today, in 2025, we don't know a ton about ball lightning.

206

So I can only imagine what they thought about ball lightning in the 1600s.

207

Ironically, we do know what they thought about ball lightning in the 1800s, as there was a few recorded accounts of experiences with ball lightning,

208

and they basically just described ball lightning as smelling like sulfur

209

and being the work of the devil which I think is fitting for the time period.

210

In case you're unfamiliar, ball lightning is typically described by witnesses as a glowing, floating sphere of light, and,

211

like regular lightning, typically only appears during thunderstorms.

212

Some people have stated that these balls are only as small as a marble, while others have said that they've been multiple feet long and wide,

213

and the colors that the ball lightning has been reported in is almost as vast as the size, with some people claiming that it was white,

214

yellow, orange, or even blue.

215

But in case ball lightning wasn't unpredictable enough, the way it behaves is also completely unpredictable.

216

Ball lightning can last anywhere from a split second to multiple minutes long.

217

And during the duration of its stay, it typically moves slowly through the air and can even pass through windows or walls,

218

typically causing no damage whatsoever.

219

And in some cases, ball lightning simply vanishes silently.

220

And in other cases, it literally explodes with a loud bang.

221

And already, ball lightning seems like one of the most amazing and also terrifying things you could witness in person.

222

And I can only imagine what witnessing it would be like if you didn't know what ball lightning was.

223

There's actually a video of a Belarusian train station that shows a ball of lightning crossing over all of the train tracks,

224

and it's just amazing to see.

225

And in the comments of this video, there's a ton of people talking about their experience with - ball lightning

226

and how the first time they saw it they thought it was an angel

227

or a ghost or something else that was typically supernatural.

228

Which I don't blame them for.

229

If I just saw this thing in front of me in person,

230

I would literally believe I was losing my mind or something really bad was happening.

231

Like I would not be in awe, I would be in terror.

232

But that's just me, if I don't know about something, I typically lean towards being scared about it.

233

But no matter how cool or interesting or terrifying ball lightning may seem, it's more mysterious than anything else.

234

Obviously, scientists don't have a concrete answer on what ball lightning is or what even causes it.

235

But there are a few interesting theories I'd like to share with you.

236

A couple popular theories that try to explain why ball lightning happens include plasma, burning particles in the air, and even electromagnetic fields.

237

And honestly, they're all kind of vague explanations and potentially could be partially true, but like I mentioned, we just don't know.

238

And one of the biggest reasons why we don't know is because of how rare ball lightning is.

239

It's almost impossible to replicate in a controlled environment, meaning that we're at the mercy of nature providing it to us to study it.

240

And as you can imagine, ball lightning doesn't roll into a lot of labs all that often.

241

And well -equipped scientists typically don't run into ball lightning all that often either,

242

leaving a lot of the thought around ball lightning to be up to speculation and based off of reviewing videos posted online.

243

And if you've made it this far in the video, let me know.

244

If you saw ball lightning out in the wild, would you be terrified or would you be intrigued?

245

I think the honest answer is both.

246

And I guess, while we're being honest, let me ask you, do you like watching

247

Trust Me Bro videos?

248

Because if you do, feel free to subscribe.

249

We make videos every single week.

250

Now, let's get on to the last section.

251

Slime mold.

252

Slime mold, or scientifically known as Fisarum polycephalum, is not mold, nor slime, nor fungi.

253

It's actually known as a protist.

254

And what makes it unique is that it's actually a single -celled organism.

255

That's right, this jelly -looking, goo -looking thing is actually one organism.

256

Although, it is full of nuclei.

257

That's right, it might be a single cell, but this one cell has so many nuclei within it.

258

And all of these nuclei actually will come in handy later.

259

Now you might be asking, what's the significance of this yellowy, greeny goo?

260

And is it even common?

261

I've never seen that.

262

And let me answer both of those questions.

263

First of all, is it common?

264

Yeah.

265

If you've gone on a walk in a forest after a rainy day, you have definitely walked past some sort of slime mold.

266

And to answer your first hypothetical question, why does it matter?

267

Well, slime molds are extremely intelligent.

268

So intelligent, in fact, that we don't know how they're so smart or why they're so smart.

269

And that is both interesting and terrifying.

270

How smart is slime mold, you may ask?

271

Well, slime molds have been shown time in and time out to solve mazes consistently.

272

And how they do this is by basically filling up the entire maze with their gooey body, and once they find the exit of the maze,

273

or in the case of the research test,

274

finding the food, they will then retract everything else that isn't directly connecting the start of the slime mold to the food,

275

allowing them to essentially reverse engineer the maze.

276

And these mazes aren't simple either.

277

Some studies have actually been able to have slime molds recreate major transportation networks, like the Tokyo subway system for example.

278

But not only can slime mold navigate to find food, they have also shown to have some sort of memory by anticipating reoccurring events.

279

And how this is shown is by having them readjust their behavior based off of previous events

280

that have happened in previous studies.

281

Proving that these single -celled organisms have some sort of memory, even though they have not one neuron.

282

That's right, slime molds have no brain, no nervous system, no complex organs, but they still seemingly can solve problems,

283

make decisions, and even remember past events.

284

And I'll be the first to say it.

285

I'm impressed with this little ball of goo.

286

And this little ball of goo might even be smarter than you.

287

But if you think the ball of goo is not smaller than you, then for who the ball of goo is not smaller than you too?

288

Okay, it is currently 1 .53am and I thought that was funny.

289

You know, I didn't even think that was funny, I just said it.

290

Regardless, the ways in which slime molds achieves any sort of intelligence to scientists is completely unclear.

291

Although, like some of the other entries on this list, the scientists have their theories.

292

And what's currently believed is

293

that the network -like structure of neurons within the slime mold allows the slime mold to process information through chemical signals.

294

Essentially allowing it to have a brain without having a brain.

295

And this method of thinking

296

or I guess thoughtlessness on the slime molds part has actually inspired scientists in specific fields like robotics

297

and computing to try to use slime molds to find clues on how to build more efficient self -organizing systems,

298

seeing as the slime mold is pretty good at doing that.

299

And while there's not much more known about the slime mold's intelligence at this time,

300

The fact that this single -celled organism can seemingly think without a brain has definitely inspired engineers and scientists alike.

301

But for now, the mind of this little ball of goo is an enigma.

302

But with that, ladies and gentlemen, that's really all the time we have for today in this episode, but I'll make a deal with you now.

303

If you guys enjoyed this video and want a part two, I'd be more than happy to make it.

304

And I actually have a lot of honorable mentions I want to discuss.

305

For example, what happened to the planet Venus?

306

Why do we dream?

307

What happens after we die?

308

How is the universe created?

309

What is dark matter and why does it make up 95 % of the universe?

310

And how long does it take to go get milk?

311

All great questions that I'd love to answer if you guys would like to hear me talk about them.

312

But that's all for now.

313

If you enjoyed this video about things that are still unsolved,

314

then you might enjoy this video on screen now about ancient mysteries that are actually recently solved.

315

That video might be a bit more satisfying than this one, considering that one has conclusive endings to every entry.

316

I highly recommend checking it out.

317

Thank you so much for watching this video.

318

And as always, trust me, bro.

Phát âm cần chú ý

Người nói dùng 57 dạng rút gọn, ví dụ don't, they're, I'm. Hãy nói theo dạng ngắn đúng như bạn nghe.

Âm “sh” và “zh”: migration /maɪˈɡɹeɪʃ(ə)n/, essentially /ɪˈsɛnʃəli/, potentially /pəˈtɛnʃ(ə)li/, medication /mɛdɪˈkeɪʃən/, harsh /ˈhɑɹʃ/
Từ dài — đặt trọng âm cho đúng: consistently /kənˈsɪstəntli/, essentially /ɪˈsɛnʃəli/, potentially /pəˈtɛnʃ(ə)li/, medication /mɛdɪˈkeɪʃən/, ecosystem /ˈikoʊˌsɪstəm/

Những âm người Việt thường gặp khó:

Cụm phụ âm cuối — đọc đủ từng âm, đừng nuốt âm cuối: mold /moʊld/, solve /sɒlv/, vast /væst/, intelligent /ɪnˈtɛlɪd͡ʒənt/, harsh /ˈhɑɹʃ/
Âm /tʃ/, /dʒ/ và /ʒ/ — tiếng Việt không có, đừng đọc thành “ch” hay “gi”: pigeon /ˈpɪ.dʒɪn/, genetic /d͡ʒəˈnɛt.ɪk/, intelligent /ɪnˈtɛlɪd͡ʒənt/, researcher /ˈɹiˌsɝ.t͡ʃɚ/, angel /ˈeɪ̯n.d͡ʒəl/
Âm /æ/ — mở miệng rộng hơn âm “e”: plaque /plæk/, navigate /ˈnæv.ɪ.ɡeɪt/, magnetic /mæɡˈnɛtɪk/, vast /væst/, rapid /ˈɹæp.ɪd/

Phương Pháp Shadowing Là Gì?

Shadowing là kỹ thuật học ngôn ngữ có cơ sở khoa học, ban đầu được phát triển cho chương trình đào tạo phiên dịch viên chuyên nghiệp và được phổ biến rộng rãi bởi nhà đa ngôn ngữ học Dr. Alexander Arguelles. Nguyên lý cốt lõi đơn giản nhưng cực kỳ hiệu quả: bạn nghe tiếng Anh của người bản xứ và lặp lại to ngay lập tức — như một "cái bóng" (shadow) đuổi theo người nói với độ trễ chỉ 1–2 giây. Khác với luyện ngữ pháp hay học từ vựng bị động, Shadowing buộc não bộ và cơ miệng phải đồng thời xử lý và tái tạo ngôn ngữ thực tế. Các nghiên cứu khoa học xác nhận phương pháp này cải thiện đáng kể phát âm, ngữ điệu, nhịp điệu, nối âm, kỹ năng nghe và độ lưu loát khi nói — đặc biệt hiệu quả cho người luyện IELTS Speaking và muốn giao tiếp tiếng Anh tự nhiên như người bản ngữ.
