#2 The Universe: What if we were wrong ? - A Wonderful Journey into History | Space Documentary

🌍 Since the dawn of time, the understanding of the universe has never ceased to occupy the minds of men. Humans, in essence, need to understand their world, the environment around them and the vast universe.
The study of the stars is part of our history and our culture. Since the dawn of time, men have sought answers to their questions in the heavens. The universe is as magnetic as the core of the Earth's center. It dazzles, it intrigues, it fascinates.

From a very young age, our eyes are attracted by the beauty of the sky. With our heads in the clouds and our minds in the stars, we dream of travelling through space and discovering its secrets.
At the same time, how can we resist such beauty? It is undoubtedly the only phenomenon that the intense and deep night sublimates with 1000 flashes. The colors, shapes and grandeur of the stars that gravitate in the Universe offer a magnificent spectacle. The stars dance above our heads to a tempo orchestrated by the universe.


🔥 As a reminder, the videos are published on SUNDAYS at 6:00 PM.

💥 The Story of Men and the Universe:
- Lift your head to the sky and look. Isn't it beautiful all those little points of light that seem to decorate the sky? This painting is Mother Nature's masterpiece. Both poetic and enigmatic, it reveals a little more of its beauty every day and lifts the veil on some of its mysteries.
It took millennia of civilization to understand a tiny part of the universe that surrounds us.
To define the universe is already a challenge in itself. It encompasses an infinite number of disciplines and we are still moving forward blindly. Too many parameters are still unknown to us. Our knowledge, on the scale of the universe, is extremely limited. But we have made great progress in recent years in the field of technology. It has become one of our best allies in understanding space phenomena.

Today, the definition of the universe is still a matter of debate among the greatest scientists of our century. Some refer to it as a notion of geometry and physics, others as an expanse, abstract or not, others still as a "container" with an indeterminate edge.

Whatever the case, it shelters an infinity of astral phenomena and we are going to discover each of them in an incredible journey. Are you ready to take in the sights and conquer space?

You take the risk of feeling infinitely microscopic, a drop of water in the ocean. But you will have the pleasure to discover an incredible place. Sometimes wonderful, almost fairy-like, it sometimes seems to be the closest synonym of hell. The space landscapes that you will discover and the amazing emotions that you will feel will remain forever engraved in your memory. These images will be imprinted in your mind just as the asteroid impacts left craters visible from the earth on the surface of the moon.

The ether was a fluid that we thought could "carry" the stars. The planets in movement, like a snake, relay on this liquid. Unlikely you will say to me to imagine such a vision of space. But don't forget that at that time, knowledge was limited and the tools of measurement and observation were few and far between, and much less efficient than the James Webb telescope.
The nature of light and its transmission was not known.
Today, we know that the space in the universe, that is to say the space between the stars, is essentially made of vacuum.
Well, empty, not quite. This "vacuum" contains enormous quantities of gas, but also a few hundred molecules and atoms per cubic meter.
We also know that light can propagate in a vacuum and that the planets, by gravitation, can move without being "supported" by any matter.
If we have succeeded in defining space, we must now understand the basis of the universe. Who is it? What is it made of? When does it begin? What are its limits?
