1
What would happen if we were to detonate a very, very powerful nuclear weapon on the Moon?
2
Would the explosion knock its orbit towards Earth, causing tidal waves and misery?
3
Could the Moon be destroyed, showering the Earth in a rain of meteoric death?
4
The Moon During the Cold War, the Moon was a major target for space exploration and, you know, military bases.
5
So, the US Air Force commissioned a serious study into the effects of a nuclear detonation on the surface of the Moon.
6
But just quoting stuff is boring, so let's conduct a very important scientific experiment
7
with an imaginary 100 megaton thermonuclear warhead about twice as powerful as the most powerful bomb ever detonated.
8
We'll also place a number of curious astronauts around the moon as observers.
9
Let's push the button and slow down time.
10
For the first few milliseconds nothing much happens outside our weapon.
11
Meanwhile inside high explosives send a shockwave to a radioactive metal core compressing it
12
so much that it reaches criticality and starts a nuclear fission chain reaction.
13
The 100 million degree plasma created in this first stage sets
14
off the second stage with atomic nuclei fusing like they do in the core of a star.
15
Very briefly, our weapon contains one of the hottest places in the universe.
16
And only now, barely 10 milliseconds later, does the rest of the universe find out that anything has happened
17
as suddenly the bomb dissolves and a flaming star of nuclear death is born.
18
So far so good.
19
But everything that happens now is very different from what we're used to on Earth
20
because of one major difference there's no atmosphere.
21
As the fireball shines it releases a flash of x-rays and thermal photons, a wave of silent heat which rushes outwards in all directions.
22
On Earth this heat would char and burn everything within a 50 kilometer radius at least.
23
But on the moon without an atmosphere and oxygen-rich air, there's no burning at all.
24
Also, there are no things to burn.
25
The crunchy top solid of the moon is made from silicate rock
26
and metals chewed to dust by eons of meteorite impacts mixed with tiny traces of water.
27
When heated by the explosion, X-rays from the fireball vaporize a thin cloud of rock from the lunar surface, while the unlucky dust that's inside the fireball melts into glass.
28
Any astronauts watching the show within about 50 kilometers can expect to be fried.
29
And now we begin to see one of the biggest differences between explosions in space and on Earth.
30
On Earth, the atmosphere fights back against the plasma bubble.
31
Its expansion is violently stopped within moments by the pressure of the atmosphere.
32
But this is not good news.
33
As the fireball rams the atmosphere, it produces the most destructive part of a nuclear explosion on Earth, the shockwave.
34
Compressed air around the explosion rushes out faster than the speed of sound, shattering buildings and roaring so loud it ruptures organs.
35
But on the moon there is no shock wave.
36
No atmosphere means nothing to impede the expanding explosion in space.
37
On the moon the fireball just grows in eerie silence as there's no atmosphere to stop it
38
or to give it a voice.
39
This would be an amazing thing to watch from a safe distance.
40
Unfortunately there's hardly any safe viewing distance for a nuclear explosion on the moon.
41
Without an atmosphere weakening the deadly ionizing radiation that can scramble DNA, anyone close enough to get a good look will be exposed to fatal amounts of radiation.
42
But of course, that's not all.
43
While all of this happens, the explosion hammers against the Moon, transferring about a tenth of the explosion energy into seismic waves, powering an intense moonquake.
44
The moon is much smaller than the earth, and our astronauts will feel an inescapable violent shaking no matter where they are standing.
45
Comparable to an earthquake of seven on the Richter scale, this shaking could seriously damage or even level infrastructure we might have built anywhere on the moon.
46
Those who hid on the far side of the moon would have no idea it was an explosion, the quaking would feel like an asteroid the size of the Great Pyramid had struck.
47
And it's not over yet.
48
our bomb explodes, the ground splatters like water when a rock strikes a pond.
49
As the explosion pushes against the surface, it may excavate as much as 100 million cubic meters of dust and rock, forming a crater 8 kilometer across,
50
while bedrock is pulverized to rubble.
51
Debris is shot into the sky in every direction.
52
Again, without an atmosphere, there's no drag to slow any of it down.
53
Much of the debris scattered never returns to the Moon, flying off faster than escape velocity.
54
A flurry of micrometeorites have been cast off to explore the solar system, many of which will rain down on the Earth, though few will be larger than pebbles.
55
Any satellite, astronaut or space station in the way, though, will have a really bad time.
56
Micrometeorites are launched at many speeds and angles, allowing them to spread all over the surface of the Moon.
57
they'll punch through our curious astronauts, no matter where they stand.
58
Finally, our explosion comes to an end.
59
On Earth, the fireball rises like a hot air balloon, forming a sort of stalk.
60
As it reaches up, cooler air is drawn in around it, rounding the top into a mushroom cloud.
61
But on the Moon, well, you know by now, no atmosphere, no mushroom.
62
The larger the plasma gets, the cooler it becomes, and the less energy it has to make interesting or terrifying things happen.
63
Within seconds of pulling the trigger, the bubble reddens and fades from view.
64
It would be visible from the Earth like a star flickering to life only to fade out right away.
65
A spark and then nothing.
66
As the cloud of tiny debris reaches far above the surface of the Moon, it's illuminated by the Sun for a few minutes,
67
giving it an eerie beauty for anyone left to observe the spectacle.
68
What about the Moon's orbit?
69
It's basically unchanged.
70
Trying to move the moon with a nuke is like trying to move a truck by blowing on it.
71
Nuclear explosions may be big, but space is bigger.
72
Our mighty explosion just leaves another crater, one among millions.
73
Still, anyone on the moon will continue to not enjoy themselves.
74
The material that ends up raining back to the moon is radioactive
75
and without any natural natural processes to wash it away or bury it, the surface of the Moon will remain contaminated. Although fortunately,
76
the worst of the radiation will have decayed to a level comparable to natural levels from cosmic rays in about a year.
77
In conclusion, we can say with confidence that while the Moon itself does not care about being nuked, and will barely notice,
78
using the Moon as a nuclear test ground kind of ruins it for everyone trying to spend some time there
79
or to build something useful.
80
So maybe we should just not do that.

Gölgeleme Tekniği Nedir?

Gölgeleme, başlangıçta profesyonel tercüman eğitimi için geliştirilen ve çok dilli Dr. Alexander Arguelles tarafından popüler hale getirilen, bilim destekli bir dil öğrenme tekniğidir. Yöntem basit ama güçlüdür: ana dili İngilizce olan bir sesi dinler ve hemen yüksek sesle tekrar edersiniz — konuşmacıyı 1-2 saniye gecikmeyle takip eden bir gölge gibi. Pasif dinleme veya dilbilgisi alıştırmalarının aksine, gölgeleme beyninizi ve ağız kaslarınızı gerçek konuşma kalıplarını eşzamanlı olarak işlemeye ve yeniden üretmeye zorlar. Araştırmalar, telaffuz doğruluğu, tonlama, ritim, bağlı konuşma, dinleme anlama ve konuşma akıcılığını önemli ölçüde geliştirdiğini göstermektedir — bu da onu IELTS Konuşma hazırlığı ve gerçek dünya İngilizce iletişimi için en etkili yöntemlerden biri yapar.
