can any body tell me when did time in the universe started?

Question

i have often wonder where time came from

Answer 1

it happened so long ago i forgot when it happened...i need to increase my dosage of ginko biloba

Answer 2

Time is only the percived amount of cycles at a set rate between events. If I know that I have a light bulb that blinks at a stready rate I might say, between the first event (light on) and the second event (light on again) one second has passed. If you run around a track and the light blinks 50 times while you ran I can say it took you 50 seconds. Because nothing was present at the start of the universe to count a cycles of constant length, the time that the universe started is indeterminate.

Answer 3

You and thousands, if not millions, of people before you have wondered the same thing. We know time is a dimension of our extended universe. But we do not know what the flow of time, from past to future, really is. Nor can we really exposit when time began. Some theorists claim time began before the big bang. Others say bull, it began with the big bang. They say this because, in their collective minds, time is entropic. That is, forward time is simply the running down of the universe after the big bang.

Read Brian Greene's, "The Elegant Universe," it has a lot of interesting things to say about time and time travel, especially in its latter chapters.

Answer 4

As per one explanation based on the quantum theory, the universe started at 10 raised to the power -43 seconds. This time is called Planck's constant. The absolute truth about it is yet to be established with certainty.

Answer 5

Good question - I guess it must have been before the Big Bang, else the Big Bang could not have occurred...

Maybe the universe is like the Genesis Project on Star-Trek2.
A dying universe was jump started back into life, and its Matrix was re-written to what we have today...

Answer 6

Time does not exist.

Initially, mankind required time in order to continue to exist so mankind created it and used it to keep track of when it was time to plant crops and things like that. Time existed only in relation to the rotation of the planet and the sun.

As mankind's knowledge has increased, he has allowed time to exist relative to the universe and begun to theorize how time might exist relative to the vacuum and infinity both of which are perplexing because they escape value and cannot be counted and only barely percieved.

The universe is comprised of an infinite value of non-sequential events only related by gravity and the creation. Time was created in a vain attempt to organize, relate, and define these events. Time does not exist.

Answer 7

According to Einstein's Theory Of relativity there can be no time without space and no space without time. So time must have started at the moment of the Big Bang.

Answer 8

Actually, time started after a certain point (after big bang) when the universe started to expand. Before that there was no meaning or sense of time and even space. Before big bang there was no 'before' or 'after'.

Answer 9

Time started when the universe did, just like the other dimensions

Answer 10

Atiq did a great job of answering your question on the beginning of time above, so I won't try to one up him.

I'd just like to point out the irony in the question itself. When did time start? How are you measuring it? There is no "when" without time. So I guess time started... at the beginning of time. Literally.

Answer 11

I *believe* it was approximatly 10 billion years ago. The Solar system is 4.6billion years old.

I could be completely incorrect on no remembering my astronomy classes at all.
