Time is understood better than you think. It is a thing which is measurable and malleable. For example, time runs slower on the earth's surface than it does in orbit. The difference is imperceptible to a person, but the difference is enough that GPS systems actually need to take it into account.

That first statement is rather circular. It assumes the conclusion that you travel through time from the beginning, when you say "i do it everyday." It's essentially equivalent to saying "I travel through time whenever I travel through time."

Examples of time travel related issues in real life:
- I noticed that time goes faster when I am sleeping.
- Through hypnosis, you can go back in time and meet your younger self, and experience past events again.
- Deja vu.
- Telescopes are time machines, if you watch a star that is 100 light-years away, then you are watching the past, something that existed 100 years ago.
- Watch a home movie of yourself and your family, you would be watching the past.
- When you look at yourself in the mirror you are not looking at the present, you are looking at an image of the past, because it takes time for light to carry the image that is being reflected in the mirror to get into your eyes, and the brain to process the information you get.

Another note, there is another possibility of experience of time travel, Holodecks, if technology allows some day to create virtual worlds in a similar fashion as the holodecks in star trek, then historical events could be simulated.

or moving at all or what it is - just havent found anything yet personally that
tells me excactly what it is and how it works, of course i have seen theorys

Also I can sometimes put my brain into this half sleeping state where my mind is racing and ten minutes seems like one hour. When I had very little sleep, I would alter my perception of break time at work this way and feel rested. Time usually seems to drag for me as it is.

For all we know, we could all be moving backwards in time and have the illusion of moving forward, although that's a philosophical concept, and it suggests that free-will wouldn't exist, in this case.

Think of the universe contracting and galaxies becoming closer until they all collapse into a single point, who knows? maybe our concept of the big-bang was reversed :P

Time is merely a persistent illusion.

Ok, I could only read the first two paragraphs, but I believe quantum entanglement is fairly old news, and it's not really a transfer of information.

That is an awesome lecture. I believe I learned more from it than an entire semester of quantum mechanics. Really makes me wish I was going to Stanford.

I really didn't want to read the whole topic before responding, so I'm problably going to say something stupid..

But.. Greek fire was invented in ancient Greek times, right? Wasn't that around 3000 years before the Islam even existed? So, why would anyone go back to 700 AD to invent Greek fire while it was already invented?

:?

But, eh. Time traveling doesn't seem that impossible. To get back on topic :roll:

EDIT: What the hell, I thought it was invented 3000-4000 years ago. Well, my history lessons slacked, appearently it was used around 500 AD for the first time. Says wikipedia. So the islam still didn't exist.

Yes, i think so too, and that guy is so easy to listen to, would have loved to have him

what he is saying

Just so we're clear on our chronologies, even if the ancient greeks invented Greek Fire, it still wouldn't predate Islam by 3K years. Even Bronze Age Mycenaean Greece didn't come along until ~1500BC, putting it maybe 2K years before Islam, and if by Ancient Greece you mean Classical (and you probably do) we're talking more like less than a thousand years. 3 thousand years prior to Islam would put us in the very dawn of Aegean Civilization.
