Is it true the universe began at a specific point in the past and it has been expanding ever since?

It is believed that it began at a specific point of time. Stephen Hawking discusses time as a vector. If it is, then there is a definite beginning, but not necessarily an end. The problem is, this is more of a philosophical or theological question and answer. Some years ago at Syracuse University at a lecture given by Niels Bohr I heard him say that Physics and Philosophy are different sides of the same coin. We may be able to pear into the sky, and see to a point that we believe may have been the origin, but that doesn't preclude something before that.

What the example of the statement the entropy of the universe can never decrease?
If a source of heat energy starts radiating from a point and continues without stop the entropy around that point will never decrease. As sun is the endless heat energy radiating source and surrounding's of that is known as universe accepted by everybody. So this is the example for the statement ' the entropy of the universe can never decrease.'
Are all objects in motion relative to the sun?
Space is vast and expanding as you read this, you could choose any point in space (even your self) and dub it as the center of the universe this site depicts it pretty well. P.S sorry if this wasn't that helpful, I'm 13 and I love science. I just so happened to come across this question and thought I could be of use.
What does position mean in physics?
the answer to your question is. a specific point or location relative to a reference point.
Water makes a good coolant because it has a . a. high specific heat c. low specific heat b. high boiling point d. low freezing point?
D. low freezing point
Speed at a given point in time?
The speed at a specific point is relative to observation point and motion of the body and therefore it should be called slip speed.
Does the big bang have a center?
theoretically, yes. There has to be an area that all the universe is expanding from. Scientists say that the universe is either expanding or contracting, and something cannot expand or contract unless expanding or contracting to/from a point. We can assume that the point is not on the side of wherever it is moving to/from. So it is not billowing out at an angle from somewhere. We can then assume that there is a center that is expanding or contracting. If there weren't a center, then scientists would be contradicting themselves anytime they say that the universe is expanding or contracting.
If all galaxies began to show blue shifts what would this change indicate about the fate of the univerese?
That would be a sign that the Universe is contracting, instead of expanding as it currently is.That would be a sign that the Universe is contracting, instead of expanding as it currently is.That would be a sign that the Universe is contracting, instead of expanding as it currently is.That would be a sign that the Universe is contracting, instead of expanding as it currently is.
Is the universe large?
at this point in time we cant claculate the size of the universe, this is because we dont have the technology to do so and because the universe is constantly expanding as you read this.
What happened to universe right after big bang?
It began to expand in size. There is a hole at that point in our knowledge of the early universe but without a doubt the universe began to expand.
How the spectrum shift of the dark line supports theory that universe began from a very small point?
1.the observed wavelength of the dark line from the distant galaxy has increased 2.therefore the distant galaxy must be moving away from the Earth suggesting the Universe is 3.expanding outwards from a small initial point
What is the theory of the big bang?
a theory that says that the universe began with a super-powerful explosion The word "explosion" carries a sense of something of large density expanding from a center point into a region of low density. This is NOT what happened during the Big Bang, despite many popular presentations that imply such an event. The Big Bang was NOT matter expanding from a center point into empty space, it was the expansion of space itself. There was nothing that this space was expanding INTO, it was just expanding.
How much did the universe increase after the big bang?
From an infinitesimally small point to the present size, the universe is still expanding as a result of the big bang.
What name do you give to the theory for the origin of the Universe?
The Big Bang Theory is the name given to the theory of cosmic expansion. The idea is of an ever expanding universe. It posits that at some point all matter in the universe was contained within one point.
Is everything in the universe stationary?
No. More accurately, nothing in the universe is stationary. There is no single fixed reference point in the expanding universe, and all known astronomical objects are in motion with respect to one another.
Who proved all the galixies in the universe are expanding?
The galaxies themselves are not expanding, and they're not all retreating out from any central point. Every point in our Universe is moving away from every other point, because the entire fabric of space itself is expanding, taking the matter along with it. Thus, every observer at any point in our Universe observes all other galaxies moving away from the point where he happens to be located. No point can claim to be the "central" point. It was Edwin Hubble, working at Caltech and the Mt. Palomar observatory, who was able to compile the radial speeds of enough distant galaxies to demonstrate the general expansion in every direction.
What will happen after this universe is destroyed?
There is no reason to believe that the Universe will be "destroyed" - it will continue expanding, and at some point there won't be enough free energy left to support any type of life, but the Universe itself will continue existing.
