Did time exist before the earth and planets were formed, and if it did, how long for. And what would space look like if there was no big bang all those millions of years ago and there were no planets or anything. Would there ever have been anything or would there always be nothing?

I want you smart people replying to this, so get your thinking hats on and give your own views/opinions. So come on http://www.isketchforum.net/images/smilies/main/icon_razz.gif.





[Useless Nino made me post it the wrong section, he is only human though]

Time is a human construction to measure things so we're not late and don't forget business lunches. Solar time and atomic time are different, which is why a 'leap second' has to be introduced to keep the two in check.

So no, time did not exist before the big bang, and didn't really exist until some crazy humans decided that they didn't want to be late for things anymore.

Did time exist before the earth and planets were formed, and if it did, how long for.

Yes, but it would not have been measureable because we have nothing to measure it with at the moment, so it's quite pointless pondering how long it existed. The big bang is our point of orgin for time, because that is how far back we have been able to trace our roots and therefore 'when time began' for us, but it's not point-blank the start of time, just of our universe. I don't think that our largest factor of time would be sufficient to encapsulate the age of time before the big bang.

And what would space look like if there was no big bang all those millions of years ago and there were no planets or anything. Would there ever have been anything or would there always be nothing?


According to what I understand of Stephen Hawking, space is filled with blackholes, where stars and universes have collapsed unto themselves under the strength of their own gravity, so before the big bang, there would have been other stars and universes, but of course we have no way of telling what they would have looked like because they're now blackholes - unless we venture so far out into space that we leave our (part of) the universe but reach another section that existed before we were created, we have no way of knowing what life/matter was there before the big bang. Our venturing so far out is pretty unlikely though, given our technology. I guess this is where it would be handy to invent something faster than the speed of light :razz:

This is what I understand from Stephen Hawking's The Universe in A Nutshell, but if I'm wrong, please do correct me!

Edit: I haven't finished the book yet.

It justs gives me a headache when thinking about it all.

I watched a two part programme on Stephen Hawking a few weeks a go on Channel 4 (did bore me a lot but I blame C4 for that )

They spoke about how each proton (I think) was like over a 2 mile radius away from each other and that everyone was connected in some sense.

I'm wondering if Humans are made up of atoms and molecules and such, then what are the atoms made of, and the things that make atoms, what are they made up? It is all rather laborious to think about.

There is no doubt in my mind that there were life forms created in other galaxies prior to the existence of the Earth and still are.


On the matter of the big bang, and what would happen if it never occurred?

When we think about it logically, how can all these things in life exist? How can space be infinite, or near about infinite?

It doesn't make sense to the average human, apart from the geeks from Nasa (and what a good job you guys do too! )

But life requires on the existence of a force of power, such as the Sun. The Big Bang is what helps creates the Sun, and without the Sun, there will be no life of a meaningful form.

I'll think I'll stop here as this sounds like it is becoming a thesis and I could go on and on and I know Ches does not want me doing that :biggrin:

Did time exist before the earth and planets were formed, and if it did, how long for.?

Time itself (along with space, matter, energy) was created by the Big Bang (the beginning of the universe) so there is no "before" the Big Bang because time did not exist then. Time did exist before the earth and planets were formed though.

So no, time did not exist before the big bang, and didn't really exist until some crazy humans decided that they didn't want to be late for things anymore.

Haha, crazy humans is true :p and it's also true that the units of time (hours, minutes, seconds etc.) did not exist until a crazed individual invented them. But the concept of "time" began existing along with the three dimensions of space (x, y, z axes for the maths geeks *cough* nino *cough* :razz:) at the moment of the Big Bang.

And what would space look like if there was no big bang all those millions of years ago and there were no planets or anything. Would there ever have been anything or would there always be nothing?

If there was no Big Bang, there would be no planets, no life, no humans, no iSketch :cry:, no forum :cry:.... nothing!

I want you smart people

;)

Atoms are made of progressively smaller and smaller units --> protons, neutrons, electrons --> quarks --> something even more labourious... I suppose scientists are looking for the most basic particle that makes up all matter

But life requires on the existence of a force of power, such as the Sun. The Big Bang is what helps creates the Sun, and without the Sun, there will be no life of a meaningful form.

Unless there's life somewhere far, far away >_>...

* Capt_Sparrow joins Nasa to meet Nino's geek :biggrin:

* Capt_Sparrow also hands out certificates for those who managed to read 'til the end :p

/me accepts her certificate

However

/me feels way too out of her league amongst the technologists, scientists, mathematicians, and engineers to even be able to respond to this thread.

Although I do know that according to Plato and other philosophers, the cosmos (which would exist because of the big bang) are the basis for ancient music theory. Everything was interconnected -- pure intervals and harmony was the sound of the heavenly bodies. Science, mathematics, and music were all united at that time...what went wrong? Nowadays, many science and math students don't think that the fine arts sudents do anything for this world. We are unimportant. *sigh* At least in Canada that's how it is.
