Because it is growing at an exponential rate.
The universe is so big and it will never be completely populated because it includes areas that are unlivable. The Earth is part of the whole universe.
The big bang was the BEGINNING of the universe so there was no temperature before it :P
as big as the secret to life, the universe, and everything, so very very big
Scientists believe so.
The universe is so big that in every empty spot in the average night sky there are thousands of galaxies
because that how it was made its never ending
The event that marks the beginning of the universe is the Big Bang. This was a cosmic event that occurred about 13.8 billion years ago, creating the universe as we know it today. The Big Bang theory is widely accepted by scientists as the most plausible explanation for the origin of the universe.
Well we don't know how big it can be because its a vast Universe so I hope this will answer it. Meteoroid can be as small as dust or as big as Everest so there no way of telling how big it can be
Because its so vast and big even endless.
The expansion of every part of our Universe was as big as our Universe -- which, if not infinitely large, is pretty big.
The Big Bang refers to the event that created the universe. It is not expected to happen again as the universe is already expanding and evolving from that initial event. However, there are theories like the Big Crunch or Big Rip which describe possible future scenarios for the universe.
The Big Crunch: Like the opposite of the big bang, the universe collapses and goes into a point of singularity. The Big Chill: The universe will keep on expanding, until there is too few galaxies and stars, which will eventually die out too, so there will be nothing in the universe but a few black holes and decayed stars and galaxies
