Sure there's some holes in our understanding of the universe, but we would get bored pretty fast if we were certain about the entire history of the universe, wouldn't we? So far, the big bang theory is the one that seems the most likely.

My personal oppinion on this topic is that the Big Bang did happen, but i don't much care for the "it was the beginning of time" thing, a friend of mine once brought this up in conversation and we cleared up thatsomething must have started that, and something caused that, etc etc.

Because if the big bang started "time", what caused the big bang to happen?

Whatever it was, it was the beginning of stuff that we can usefully discuss. Whatever there was before the Big Bang, it's not anything we can discover or even theorise about. There's an infinite number of possibilities which could theoretically exist outside the time and other dimensions of our universe without affecting it, and since all are equally valid in lieu of any evidence about them it's not worthwile to discuss.

We are....

my friend had a really good theory.

basically the big bang was the absolute start of time. what happens is that time travel is possible because you traveling back in time and changing stuff is already predetermined in time.

after mankind gets very, very advanced, we travel back in time and cause the big bang.

of course, it's one of the infinite possibilities.

If you define the big bang as the beginning of time, there is no such thing as "before" the big bang, and therefore it is physically impossible that something inside the universe caused the big bang. Of course you can say something outside the universe created it, but then it's more of a fairy tale discussion than a physics discussion.

So whether you define it as the beginning of time or not, there's no causality issue.

No, it's not one of infinite possibilities. It is self-contradicting on so many different levels.

Determinism, AND travel time? Hasn't your friend heard about the grandfather paradox? What if someone goes back in time to kill his own grandfather? If, like you say, everything is pre-determined, then it was determined that the grandfather dies before his son gives birth to his grandson. But then, it would mean that the grand son would never be born, and therefore not kill his grandfather. That means the grandfather WON'T die, so he WILL give birth to his grand son .. etc etc, it goes on forever. It's a paradox. That's why time travel can't work in this universe.

I won't even bother to explain why it's impossible for us to create the big bang, which you say is the absolute beginning of time, because it's so blatantly self contradicting.

ah but if everything is predetermined, then if that person goes back in time to try and kill himself, he will fail in his mission, because his grandfather was alive long enough to have a son, and then that one had a son.

if it's predetermined that that guy lived long enough to have a son which then in turn had a son (or daughter or whatever) then it would be impossible for anyone to go back in time to kill him. that's why if time travel is possible, the genocide would still happen.

or it could be that one thing that was explained in a great book series i read where if you kill hitler, someone will replace hitler therefore time will have fixed itself.

You're dodging the whole point of the paradox. To make it simple, let's change it a little. What if someone decides to go back in time to when he was a baby, and kill the baby? It's a contradiction, no way around it. It either makes time travel impossible, or causality wrong (in our universe, we assume causality is a constant).

or it could be that one thing that was explained in a great book series i read where if you kill hitler, someone will replace hitler therefore time will have fixed itself.

What makes you think it's garaunteed that if you kill baby Hitler, someone will replace him ?? No one will have the exact same genes / brain as hitler, and no one lived exactly the same life as him, so why would someone make the same choices as him? It's absurd.
However, even if we assume it's possible, the only thing it changes is the history textbooks. It doesn't remove the paradox.

Well, I'm just having the most difficult time
deciding which conversation to join in on.

Big bang theory...no.
Haircuts...maybe later.

Nah, I actually had some to say, but I didn't feel like it. :3
Was going to say that my hair is currently longer than
yours was before you cut it.
And I got mine cut a week or two ago.

And before any of you guys think my hair
is an overgrown unmaintained mess,
think again. My hair is simply gorgeous.

That wasn't self centered at all. ;)

I think the men in black theory tops all, our universe is inside a marble and theres like a bajillion marbles XD

Timetravel
Even if you time travelled somewhere but did nothing everything would still change because for example the Butterfly Effect.

Every little counts. As stated by the chaos theory.

Sorry for the double post, but I was just wondering if everyone could recommend my Pico Day submission into the collection. becasue shamefully after 3 days it doesn't seem to have made it.

If you went back in time and did something specific to change the future, that thing will have changed and that alternate ending you created will have happened and you'd never have gone back in time to change it in the first place.. it's an infinite paradox. Time travel isn't possible >=/

A paradox doesn't prove that it's not possible. It might be possible to reverse the direction of time, or to create a timespace warp across time.

Paradoxes in time travel are resolved if you consider multiple parallel universes, where going back in time doesnt land you in the same timeline as before, but splits an alternate one off at the point where you traveled backward in time.

It's pointless to think or debate about really, how about we discuss something practical?

Yeah, I was halfway through a sentence about quantum mechanics when I decided I couldn't be bothered adding that to the mix :p

I'm 2 weeks from the end of my first year at uni, only just starting my assessments which are to be handed in during the last week, I'm looking forward to finishing my work and having free time - not that I do anything whilst I'm here anyway, but it's not technically free time whilst I have work to do.

What is everyone planning to do for summer?

I'm a bit torn - I have a house here next to my uni with my friends starting in June, but I also need to go back to my parents, I also have a job there and I really should get some money. I want to buy a gaming PC, plus I'm going on holiday in mid june and I have Leeds festival and going to London at the beginning of August for NG meetup. Only one of those I haven't paid for is london (i.e., a train ticket) but that shouldn't be too much.. just £100-200 spending money =p

That's what i was thinking.

Time Travel

I think scientists are doubtful that you can go back in time using any sort of machine, energy or device, time is a river, you can't go against the current. However, you can swim with the current and go forwards in time, or rather, speed it up. It's already been done, albeit on a small scale, with astronauts coming back older than they would have been on earth.

However, with parallel universes, like glaiel said you could just jump out of your river into a completely different one, go back upstream and jump back into ours.

I'm just going on what i'm aware of, i'm sure glaiel is going to come kick my ass with his physics.

That's just a byproduct of relativity. And I think that they just slowed down everyone elses time for their reference frame.

As for the whole river thing, space and time are probably a lot more fluid than people think. Imagine a piece of paper that you can only move in one direction across. You can't end up further back than you started, right? But if you fold the paper over itself and hop across to an earlier point, Bob's your uncle.

that image was pieced together entirely from overheard discussions in the college bar, btw, so don't hold me to it

In any case, as ad hoc and self-contradictory as most of these arguments are, it's good to see discussion this place branching out into a really interesting area :P
