Is time infinite in both directions?There will always be a yesterday & tomorrow.?

Question

All the theorists who believe 'The Big Bang' was the beginning of everything and that all matter in the universe came from it, this gigantic star that must have stood alone in an endless void, must have had a birth in itself. Where did all the materials it was made of come from? How long did it stand alone for? Was it moving ? It doesn't make any sense. Time must be infinite, no end or beginning, it's like the chicken & the egg. The Universe we know is without doubt the result of one giant object exploding, indeed still spreading out today, but logically one of many such explosions in a void that is without a start, without an end, without boundaries. The more your head hurts trying to fathom it all out it makes you realize why so many choose Religion instead ah! ah! ps. Love to hear others views.

Answer 1

Time of course is a concept that means a lot to us - because we 'conceived' of it...and because our lives are so short (in relation to cosmic matters) that we become very conscious of how swiftly it begins to pass as we grow older.

Time is also an important factor when you try to 'grasp' the nature of the dimensions that exist beyond this one.

As far as the Big bang goes...if indeed your assertion that (quote) "The Universe we know is without doubt the result of one giant object exploding" (hmm, without doubt, eh?)...then whilst your confidence that this must be one of an infinite number of such explosions in an infinite void - the question remains... was there a point when the first of these series of explosions occurred? If not the proposition must be that there 'just was' an infinite void. and there 'just was' some sort of 'massive stars' (presumably separated by distances so huge that to the human mind they 'tend' towards being infinite), and they periodically just 'explode'..then how come these things just 'existed' in the first place?...

It would seem reasonable to suggest that indeed...religion and 'the existence of an infinite universe' - are not mutually exclusive concepts (as suggested by the idea that an Infinite universe is so 'boggling' this is why some people 'turn to religion' - as if it may be 'one' OR the other)

We have the 'arrogant' tendency to conceive of 'God' as being a big, powerful, 'Man-type' being...But if for a moment we accept this is actually plainly ridiculous - and that God (or the true force of creation of our Universe as far as we can ever know it!) is actually an 'entity' (for want of a better word to 'represent' something that cannot possibly be named, represented, or described by means as inadequate as mere human words) that 'exists' (although existence is again a human concept - and presumably it is also an inadequate word for decribing the 'state' the God is 'in' at any point in human time) throughout the 10 dimensions - and can trigger the very vibrations of the 'strings' that cause the emanations that ultimately represent all the 'stuff' that our Universe consists of. Then maybe we can begin to se how our Universe and God relate.

The notions of 'strings' being responsible through their vibrations for everything that we have known, do know and will ever know (within the excruciatingly limited capability of the human brain and mind) is amazing enough - and the fact that 'God' may be as a 'multi-dimensional-wind' or 'energy' or 'formless, massless, simultaneously infinitely small, yet also ubiquitous' thing...that causes the tremors in the 'strings' from which evolves the basis of those Dark materials and energy that ultimately filter through the dimensional layers to cause an array of chemicals to associate, agglomerate, combine and 'become' the planets, the galaxies, the stars, the suns, and even to trigger the evolution of a 'simple life form' like Homo sapiens...then this is truly...as you say...enough to make your head hurt...

Answer 2

Time does indeed have a direction, and it does indeed have a beginning. Whether it has an end is an unresolved question.

According to today's best theory, the Big Bang began a small fraction of a second after the beginning of time. Since the infant universe was changing extremely rapidly then, the fraction of a second is important.

The beginning of time colincides with a quantum fluctuation. It only had to happen once, and everything follows from that.

The laws of physics -- Newton's, Maxwell's, Einstein's, and quantum mechanics -- are insensitive to the direction of time. But there is one condition in the early universe that gives time its direction.

In thermodynamics, there is a law of constantly increasing entropy -- of constantly increasing disorder. By itself, tghis law is also insensitive to the direction of time.

But we see an egg roll off the table and splatter on the floor. We never see a splattered egg collect itself from the floor, and then rise intact to the tabletop. This illustrates a change in entropy.

In our ordinary experience, we see that entropy increases -- the egg falls down, not up -- and if entropy is increasing on one particular direction, then the universe in the distant past (near the beginning of time) must have had extraordinarily low entropy; that is, it must have been very highly ordered.

And according to the theory, it was. The "inflationary" period near the beginning of the Big Bang smoothed out the universe to a very high degree, giving it a uniformity that has become increasingly disordered ever since.

That means entropy constantly increases throughout the universe, and therefore time has a direction.

Answer 3

Actually, time's arrow has been theorised to run in both directions. Newton treated time as an absolute, the same no matter where you were in the universe and at whatever speed you were travelling with respect to other objects. The along came Einstein and theorised that time and space were more interlinked that we could ever have thought. His theories about relativity have been proven right by the proof of time dilation - the faster towards the speed of light you travel, the slower time passes IN RELATION to the person or object at rest. A few years ago they flew a case of bang accurage caesium clocks around the Earth a few times on supersonic jets. They left a case of these clocks on the ground. Guess what? The clocks that had been whizzed around the Earth were slower than the clocks on the ground. Time dilation. The theory is that if the universe one day stops expanding, then it will begin to contract, if there's sufficient matter in the universe to attract it all back together again. At this point, time and space may collapse back to the infinitely dense and hot singularity that is thought to have been the birth of the universe. Space, time and energy are all intricately connected.

Incidentally, you were talking about stars. They coalesce slowly out of the gases in the interstellar medium, until mutual gravity causes enough matter to collapse under its own weight and ignite into a stable fusion process, as our own sun has done for the past five billion (5,000,000,000) years and will do for the next five billion years. If Jupiter had been ten times its current mass, it might well have had sufficient mass to ignite into a dwarf star - which is the point of Arthur C. Clarke's 2001 / 2010 stories.

Sorry to rant on, but these ideas have fascinated me all my life. We live in an astounding universe. Wheather by design or creation, its size, scale and balance are literally breathtaking.

Answer 4

If you want a scientific view and believe in Big-Bang, then time is not infinite in this direction. It had, at least, a begin. Scientists find that the Sun had a birthday and will die... I think you know that:
If you can accept a philosophical explaining, then the better I have met till now is that. We live in a part of Universe called emergency order. It began with the Big-Bang. It is inside a wider space with a very particular characteristic and called 7th Cosmic Region. This region is under a law: everything that is born will die. Our Universe, as part of 7th Cosmic Region is under this law and so it was born and will die. Considering this view point, for us - humanity -, time had a begin and will have an end.

Answer 5

Before the Big Bang, there was the singularity. The singularity was a single point in space that contained all of our present day universe.

If you were to drop the complete works of Shakespeare into a singularity, all you would get is a fatter singularity. The literature would be gone.

Because of this effect we cannot know what existed before the Big Bang. We cannot even know if the physical laws were the same. The Gravitational Constant, Plank's Constant, etc. may have all been different.

So we say that the Big Bang is the day that time began.

It might be more accurate to say that it is the day that history began.

Answer 6

You miss the point of the big bang. It doesn't have to be the beginning of things, just a point beyond which our ability to predict the actions and interactions of matter and whatever else, breaks down. It is perfectly possible that before the big bang, our universe didn't exist, at least not any sense we could understand. Perhaps it was the result of the collision of 2 or more multi-dimensional membranes, each with a coating of strings.

Answer 7

the historic Hebrews could have stated that throughout a experience previous and destiny are kept, because the destiny is the unfolding of the previous, making all of them element of an total. the historic Greeks, who've maximum influenced us, adhere more effective to the linear view of progression. The Hindu's believe the international ends each 6,000 years, rests for a a million,000 and then starts the cycle all yet another time--diabolical philosophy that one, to my recommendations, invariably trapped on the wheel of karma. i imagine, now that we are all the way down to non-public reviews, that element began with the initiating of the universe, that there's a level previous which we gained't bypass in our wondering about the initiating of issues; and that element, contained in the experience of a temporal rhythm of existence, will continuously bypass on. At this element time is warped with the help of entropy, yet i imagine a time will come at the same time as time will be warped with the help of no longer something, and the bypass will be suited. The musings of one who holds to the Biblical view of creation contained in the e book of Genesis, and the Biblical view of the top time in Revelation. hello Ho, Maggie !

Answer 8

You can always look and travel to the past, never the future. Since there was a beginning is not infinite for the past, but for the future.

Answer 9

While time may be infinite there is in reality only now. Yesterday's gone and ceased to exist, Tomorrow has not arrived so may not exist.
Be happy with now and enjoy, it's less confusing.

Answer 10

spirit teaches us that in their world, there is no future and no past, there is only the present.
Linear time exists on Earth to give us a feeling of constant change and our eventual mortality for how can you die when there is no next second, minute, hour or year?

Kind of makes your head hurt if you reflect on it too much, but perhaps that's to stop you doing it.
