1
Astronomers have discovered thousands of planets orbiting stars other than the Sun.
2
They come in all sizes, at different orbital distances from their stars.
3
The closest of them are trillions of miles away, and even the largest are just fuzzy patches in the fields of high-powered telescopes.
4
But if one of these planets is close in size to the Earth
5
and orbits not too close and not too far away from its parent star, it could be rocky and warm enough to have oceans and perhaps life.
6
Astronomers discover these potentially habitable planets, and their eyes get big and wide.
7
Could one of these distant worlds carry the building blocks of life?
8
Or even a living, breathing civilization?
9
Is the question, are we alone in the universe, about to be answered?
10
But wait, maybe we should ask a different question first.
11
Should we try to find out if we're alone in the universe?
12
If we do find the atmospheric fingerprints of life on one of these small, distant worlds, should we try to contact any beings who may live there?
13
Is that wise?
14
Three decades ago, NASA decided the answer was yes.
15
Voyager 1 and 2 were launched in 1977 to explore the giant planets in the solar system.
16
Each spacecraft carried a golden phonograph record—a time capsule of sorts—that included included clues
17
and messages meant to convey the story of human civilization.
18
The contents of these gold-plated copper disks were chosen by a committee chaired by American astronomer and author Carl Sagan.
19
They included over 100 images and a range of sounds from the natural world, ocean waves, thunder, the sounds of birds and whales.
20
The records also included music from many different time periods and cultures,
21
greetings in 55 languages, and messages from the President of the United States and the UN Secretary General.
22
They also included a map.
23
Each golden record displays the location of our solar system with respect to 14 pulsars.
24
Their precise, unique frequencies were indicated, so that intelligent extraterrestrial life forms could use them to find the Earth.
25
Many years later, renowned physicist Stephen Hawking said
26
that it was a mistake to give an alien species a roadmap to our planet.
27
Hawking suspected that any extraterrestrial life probably wasn't any more complex than microbes,
28
But he warned that if an advanced alien species did visit Earth, it could be as catastrophic as Christopher Columbus's arrival was for the Native Americans.
29
Meanwhile, the golden records continue their journeys.
30
In 1990, both Voyager spacecraft passed beyond the orbit of Pluto.
31
Voyager 1 entered interstellar space in 2012 and will reach the nearest stellar system in 40,000 years.
32
If either spacecraft is discovered by extraterrestrial life, there's a possibility that they could decipher the clues from the Golden Record and one day reach our planet.
33
That's particularly true if theirs is a much more technologically advanced civilization.
34
That life could be benevolent, as we would hope to be if humans are one day able to achieve interstellar travel.
35
Or it could be hostile.
36
Searching for planets that might have life means staring into a great abyss.
37
We'll likely have no clear knowledge of the evolutionary stage, sentience, character, or intentions of the first form of life we discover.
38
So it's a risk to turn our eyes outwards.
39
we risk our very way of life.
40
But it may be a greater risk not to look, to deny the very pioneering spirits that help shape our own species.
41
We are all born curious about the world and the universe.
42
Pursuing that curiosity is one of humankind's greatest achievements.
43
Perhaps there is room to push the frontiers of science, provided that we cradle, alongside our fervor,
44
another of humankind's greatest assets, hope you

نصائح للممارسة

لتحسين النطق باللغة الإنجليزية من خلال shadow speech، انصحك بمتابعة الفيديو بتركيز. ابحث عن مقاطع معينة في الفيديو تتعلق بالمفردات والعبارات التي تم ذكرها. حاول استخدام طريقة التظليل في الإنجليزية من خلال الاستماع إلى المتحدثين وتقليد نغمة الصوت، السرعة، وإيقاع الكلمات. من المهم أن تكرر الجمل ببطء في البداية، ثم تزيد من سرعتك تدريجياً لتناسب نغمة الحديث الطبيعية. تذكر أن shadowspeaks يمكن أن تكون وسيلة فعالة لتعزيز مهاراتك في النطق والتواصل، لذا يعد موقع ممارسة shadowing site مكانًا مثاليًا للبدء. من خلال استخدام هذه التقنيات، ستتمكن من تعزيز لغتك الإنجليزية وتحقيق الاتقان بشكل أسرع.

ما هي تقنية التظليل الصوتي؟

التظليل الصوتي (Shadowing) تقنية تعلم لغة مدعومة علمياً، طُورت أصلاً لتدريب المترجمين الفوريين المحترفين. الطريقة بسيطة لكنها قوية: تستمع لصوت إنجليزي أصلي وتكرره فوراً بصوت عالٍ — كظل يتبع المتحدث بتأخير 1-2 ثانية. تُظهر الأبحاث تحسناً كبيراً في دقة النطق والتنغيم والإيقاع وربط الأصوات والاستماع والطلاقة.
