What happens if our universe collides with another universe? Scientist: the consequences are worrying

What if our universe collides with another universe?


So far, the only potential evidence of cosmic collisions we have found is the existence of “cold spots” in our universe. In 2013, the Planck satellite data released by the European Space Agency confirmed that this region with a diameter of 1.8 light years is not only much cooler than other regions in the universe, but also seems to have 10000 fewer galaxies.

At the beginning, scientists were puzzled about the existence of this region, but now some scientists have theoretically proved that this region may be another cosmic collision, leaving a “wound” or “bruise”, but how can we be sure? And even if so, when will the next touch happen?


Before I go any further on this topic, let me take a moment to solve another problem that bothers you a lot. Generally speaking, the universe we refer to refers to all space and time, including planets, stars, galaxies, and all other forms of matter and energy.


So, if the universe means everything that exists, then logically, the universe has and can only have one, right?

In fact, some scientists believe in the concept of multiverse. According to the multiverse theory, our universe is not the only one produced from the big bang. Besides our universe, there are infinitely many universes. We just haven’t found a way to detect and calculate them yet.


If this theory is correct, we can speculate that all these universes expanded at the same rate after the big bang. If this is the case, they may collide in the process of expansion. Let’s go back to the problem of “cold spot”, which is a region of our universe whose temperature is 0.00015 degrees Celsius lower than any other region. It doesn’t seem like a big deal.


But considering that the temperature of other parts of the universe is highly consistent and constant, scientists are beginning to realize that this may not be just an abnormal phenomenon. They think that this “cold spot” may be a trace left by a cosmic collision, and this collision may cause the energy of our universe to leak from the “cold spot”, leading to the low temperature of that area, But what would such a big collision look like?

We’re not sure, but some people have put forward some cool ideas.


A physicist from the University of California said that if another Universe collides with our universe, because the cosmic wall will reflect light, it will look like a huge mirror flying towards us from the sky. If this universe collides with our universe, there may be a set of new physical laws to “take over” our world, and gravity may weaken, even disappear, leading to the collapse of the universe A large number of planets break away from the control of stellar gravity and fly into space at an extraordinary speed. Without gravity, stars no longer exist.


We will live in the endless darkness, which makes the existence of most life on earth and even in the universe almost impossible.

If there are no glowing and heating stars, human beings will lose all the sources of nutrients, even the air they can breathe. Plants can no longer convert the light energy of a star into energy through photosynthesis, which sounds terrible, but we don’t have to worry about it, because the probability of our universe colliding with other universes is almost zero.
