Anonymous users2024-02-06The universe has no boundaries, and human beings can never reach the boundaries of the universe.
The reason for not being able to reach it is not that you will die before you reach the end of the journey, but that the journey itself has no end. The most popular theory today is that the universe is expanding and will continue to expand forever, and that as a result of this expansion, distant galaxies appear to be receding at a speed very close to the speed of light. So, at the speed that modern technology is possible (the space shuttle can reach speeds of 10,000 kilometers per hour), you may never be able to catch up with the boundaries of the expanding universe.
It's a race that you can't win, so to speak.
The universe actually has no touchable borders. As many have pointed out, if the universe were curved, it would fold backwards on its own to form a shape without any edges, like the surface of the earth. If you go in one direction on Earth, eventually you will return to the starting point.
The same may be true for space – if you go in one direction, you'll end up where you started. Even if the universe doesn't tilt to the point where it folds itself backwards, you still can't reach its boundaries because the universe is infinite.
Forget about the expansion of the universe and the shape of the universe, hop on a space shuttle and fly at a speed of 140,000 kilowatts toward the farthest object we can see, about 10 billion light-years away. But frustratingly, the calculations will tell you that your journey time will be 75 trillion years. By the time this result is seen, the age of the universe is well over 15 billion years.
What happened to the universe at this time, no one will know.

Anonymous users2024-02-03I think the universe has no boundaries. The universe is vast. The range of human reproduction is simply not perceptible to the changes in the universe.
Boundless, but with a detectable limit, the horizon, beyond which we are agnostic (the horizon is the universe at the moment).
The universe has edges, just like our earth, the universe is a sphere, so everything born in its body is born according to the universe itself, so it can be seen that the universe is round. Therefore, beyond the edge of the earth is the universe, and beyond the edge of the universe, I guess it should be chaos, how big the universe is for us, how small it is for the universe, there may be a universe beyond the universe, but it is as distant and unreachable as we humans looking for our kind, even an illusory fantasy. For Chaos, our universe is like a stone, a small stone, a stone that produces life. >>>More
The outside is the same as our universe, the universe comes from the big **, belongs to one entity, and it should also have another entity on the outside.
The landlord wants to ask if there is any other life in the universe, right? The following answer is my own hand typed out before, very suitable for the landlord's question, now copy it, I hope the landlord doesn't mind. >>>More
The universe has no boundaries.
The universe is infinite, because the universe refers to the sum of all material space and time, and time is infinite. >>>More
