Does the universe (according to big bang theory) continue to expand until today?

Question

Just Answer yes or no but as much as possible please explain... Thanks! Answer your best remember It's 10 points...

Answer 1

Yes, but it is the other way around. The big bang theory is a result of the fact that the universe is expanding at the moment. Since it is expanding, it must have once been much smaller, and before that it must have occupied no size at all. That instant is known as the big bang.

The traditional theory said that most of the expansion was at the start and as the galaxies got further apart they slowed down due to gravity pulling them all back towards each other, but recently it has been discovered that the expansion is actually getting faster. No complete explanation of this has yet been developed.

Answer 2

It is a good question. A possible answer goes something like this. There may be multiple ways a Universe can fail to exist, could for instance collapse in on itself in fractions of a second, hours or thousands of years after it formed. There is nothing to say that the Universe we see is the only one that has ever existed. It may well be that it is just one in a very long line of different versions of a Universe, each with different forces of gravity, electromagnetism, fine structure constants, or nothing like these at all. It is just one that can persist for multiple billion years, which seems like a long time to us but to a "greater reality" is not much at all. Because it is one of the versions of the Universe that can persist, and it has a few other features, then stars can form, then planets and life can develop. There are some things that have come out of centuries of scientific effort. The Sun is nothing special, there are millions of stars just like it. The Earth probably is nothing special either, it is just one planet of more than 300 that have been detected so far, each of them different in some ways, each of them similar in many ways. Biology teaches us that humans are nothing special in much the same way. So why should the Universe be anything particularly special? Why isn't it just one in a long line of Universes that lasted nanoseconds or billions of years? Or why is it not one of millions of Universes that exist right now, many of which are lifeless?

Answer 3

Yes. The Universe will continue to expand forever. Currently, it is expanding faster than previously thought. The Universe is basically expanding into nothing. The Universe started out as a tiny ball of energy and expanded out into what today is the Universe, and it continues to expand.

Answer 4

They say yes, but I don't understand why Scientists do not hypothesize that the Universe is round instead of endless. I believe that, as it would be on Earth, if I go straight in one direction for long enough (possibly for millions and millions of light years) I would eventually end up at the starting point. We just have to find a way out to see what lies beyond the universe, but we can't travel that far yet...so it is not possible to even check this theory.

Answer 5

The universe is expanding to-day,but it is finite and will end, one day.
It can't be in an accelerated expansion,it would reach the speed of light,which can't be.
It's like a hurricane,it started from a wisp,roared into a maelstrom,faded out and died.
We are in the midst of the hurricane now.

Answer 6

Yes .. It does expands and we are moving away as fast as a rocket. Life cycle of a universe is inevitable and soon (just 60 million years) our sun will die..

Answer 7

galaxies are gradully getting further and further apart from one another and new starts are born and die all the time...who knows mabye theres another big bang happening another trillions of light years away

Answer 8

Yes, and the expansion is accelerating. The probable cause is the unknown dark energy........

Answer 9

according to big bang theory?..of course
