Infinite Universe

One of the biggest questions 0_____ modern science is whether the universe is finite. There is no clear or definitive proof that the universe is either infinite or 1 , although both sides of the argument have supportive evidence. What we know for sure is that the Big Bang took 2 13.8 billion years ago, so this is approximately how old our universe is.

One of the methods to measure the size of the Universe is through light that we can see. However, due to the expansion of the universe, the farthest light we have been able to detect is about 46 billion light-years 3 in all directions. In the first moments of the universe after the Big Bang, the volume and density of matter were more or less the same, but as they cooled down, the regions of mass accumulation and the regions of empty space became more defined. This is why we can detect light 4 a distance of 46 billion light-years, even though our universe has 5 in its current form for only 13.8 billion years.

Although we can’t currently see the curvature of the universe, it has been suggested that if the Universe were at least 250 times larger than our currently observable Universe, it could potentially still bend backwards, somewhere beyond our 6 to see. Discussions about the Big Bang, the size and shape of the universe, dark matter and dozens of other 7 topics continue to fascinate experts who spend their lives 8 at the stars.
