Scientific Research & Self-Development Activism
I am not a scientist and I do not know much about physics. This might be more of a philosophical discussion.
Before the big bang, many theories claim that time did not exist. Time as we know it is the fourth dimension we know here on earth. We cannot move in time like the other dimensions, not yet at least, because we cannot cross the speed of light. I saw a documentary on discovery with Stephen Hawking's theories on time, where he claimed that time travel was possible and happens all the time (unfortunately part 1 has been removed: http://www.youtube.com/watch?v=ykQZAgJJnSI). Extremely small wormholes are around us all the time, and if we could make these bigger and travel through them, then we would indeed travel in time. This can also be used to reach planets faster then normal. We just don't have the technology yet.
This leads me to the questions, What was there before the big bang theory? Did time exist?
You can only take a guess on this question, since even the most talented scientists have not answered this yet ;b
Basically you need to think of the idea of "Information Travel".
We have a law called "Conservation of Information" in physics, this is similar to other laws such as the conservation of Energy, conservation of Mass, and conservation of Angular Momentum. There are others.
Basically what you are asking is how can we see into a land where these laws do not hold true.
The fact of the matter is that due to the law of Conservation of Information, we will never know what lies beyond the borders of our universe in any of the 3 spacial directions or the 4th direction you mentioned... time.
The only way we can find out what happened to create our universe is to make observations of how it behaves and maybe this can give us a clue to how it formed. Or perhaps you could invent some sort of machine that could allow you to travel "Outside" our universe that holds planet Earth.
The truth is that is way too far from our horizon of possible understanding right now and as much as it hurts me to say this, you really should consider asking different questions because even the top theoretical physists right now are light years away from coming to a conclusive answer on this. They probably never will. Especially if we don't start fixing some of the social problems that we currently have in the world. We may destroy ourselves long before we find the true nature of the universe we live in. Sorry though, wish I could help but that is a very grim topic and the truth of the matter is the answers that you seek are currently utterly unavailable and any discussion on the topic really is just speculation and idea throwing. Which of course is good, but don't expect the intellectual nourishment you are looking for.
I hope you're familiar with the Kalaam cosmological argument. I know you fellas on this site will think I'm just spreading religious propaganda, but I'm just stating my views on what I find to be very relevant topics :)
Here it goes"
The Kalām cosmological argument :
Perhaps there was time/space before the Big Bang, we'll never know until we die (And we might not even find out). However, I happen to believe that the universe and all physical existence had a beginning. But thinking about what was around before time is a mindfrag ಠ_ಠ
I think we should not come to the conclusion of a God as a creator when we do not know much about the universe and about God. this is a video that explains the failure of the Kalam Cosmological Argument http://www.youtube.com/watch?v=u_676IeyJNQ
What took place before something that isn't proven seems irrelevant to me. I think that our true answer will present itself as we learn more about the universe itself.
If you were the size of an ant, do you think that you would ever know whether or not the earth was round?Now what if you were the size of an atom? Would it make sense for a person that small to think about how the earth became round and what shape it could have been before?
Now I am as open minded as anyone, and i don't think that answers are hopeless to strive for, but proof is always in the pudding.
Thanks for reading!
Time before Big Bang?
There are infinite Big-Bangs.
The universe is in a continously contracting, expanding,contracting,expanding,... to the infinite
Without time this universe is impossible to exist. To exist universe needs TIME and SPACE.
Maybe Im wrong.
This is what I understood from discovery channel XD
