This is the universe. This little point here is the earth. This is a huge rebound that is coming and it is about to squeeze our planet. UPS. How long will the earth be crushed to nothing?
What will we observe from below? What will happen next? It is generally believed that the universe originated from a point of infinite density and then expanded rapidly in what we call the Big Bang.
But when it happened, no one around saw it with their own eyes. So here is a new theory. What if all of this didn't start with the Big Bang 13.8 billion years ago? Rather, what if the universe did not begin or end, but instead expanded and contracted over and over again?
Circling the universe involves a series of great bounces, in which the universe is like a huge cosmic lung, each bounce will inhale and exhale a great breath. Basically, you have nothing to worry about. Because the cyclical universe expanded for billions of years and then contracted for billions of years.
On the human lifespan scale, this timeline is not developing fast enough to affect you in any way. But at Y SI we want to add some fun to our story. In this case, we will accelerate and let the universe go through its bounce cycle almost every day.
The next bounce event is scheduled for tomorrow. You'll start the day with disturbing news from astrophysicists. Stars and galaxies are generally slowly moving away from each other and will now move closer to each other. And fast. Every planet, every star, and every galaxy at the edge of the universe will rush towards its center, breaking the limit of the speed of light in the universe.
Black holes will collide with other black holes. They emit large amounts of cosmic radiation in all directions and grow into larger black holes. No planet in the universe already has a stable orbit. They will fly through the galaxy and find themselves in the "center of the city" of the universe. At this point, things on our planet will get very complicated. You won't be able to do anything to stop it.
So sit back and watch the end of the world. As the universe continues to collapse into itself, its temperature will increase rapidly. Excessive temperatures can evaporate our oceans, our planet, and even our atoms. Everything that once existed will be wiped out. Finally, when the universe shrinks to its densest point, it will become a mixture of superheated matter and dense matter.
It will slow down for a while, and then suddenly it will start to swell again. A new rebound cycle will begin. A whole new universe will appear. New universe, old rules. From the hot cosmic dust, gravity will form new planets, new stars, and new galaxies. Then new life forms will appear in those new worlds. This new universe will continue to expand until it reaches its limit. Then it will turn back into a hot, dense ball of matter. This cycle will repeat itself. Then again. Then again.
But we are too far away to know. Well, the result is a bit dark. But hey, the universe is only 13.8 billion years old. Before the contraction begins, we still have billions.
