Why is there a speed limit in the universe? What happens when the speed is infinitely close to the speed of light?
In Einstein’s special theory of relativity, one of the most important theories is the theory of constant speed of light, that is, the speed of light in the true sky is constant under any reference system, and the speed of any object will not be greater than the speed of light.
How many stars are there in the universe? Much more than the sand on earth
At present, the range of human observation is 93billion light-years, which is a terrible number. As we all know, the speed of light is the fastest material in the known universe. 300000 kilometers per second can make seven and a half circles around the earth in one second.
Physicists say our real world may be only half of the two interacting worlds
In a new paper in physical review research, Victor galitski, a researcher of the joint quantum Institute, and Alireza parhizkar, a Jqi graduate student, studied an imaginative possibility that our real world is only half of the two interactive worlds.

Is the Great Wall in the universe, which is 1.3 billion light-years old, the boundary of the universe or the huge wall?
The Sloan Great Wall is the second largest structure in the known universe. It is about 1 billion light-years away from the earth, and its length has reached an amazing 1.37 billion light-years, which is three times the length of the cfa2 Great Wall discovered in 1989.
