Time Travel theory explained in simple terms (video)

"Light, it turns out (consistent with Einsteinian physics), is much more effective at twisting space and time"

My comment: When it comes to science, don't say the word "Impossible" too hastily. :thumbsup

With that said... there ARE serious obstacles to overcome:

"Finally, Olum and Everett note a theorem proved by Stephen Hawking in a 1992 paper on the chronology protection conjecture,[7] which demonstrated that according to general relativity it should be impossible to create closed timelike curves in any finite region that satisfies the weak energy condition, meaning that the region contains no exotic matter with negative energy. Mallett's original solution involved a spacetime containing a line source of infinite length, so it did not violate this theorem despite the absence of exotic matter, but Olum and Everett point out that the theorem "would, however, rule out the creation of CTC's in any finite-sized approximation to this spacetime."

Great more funny experiments with the light !

^^

.

The ripple effect time travel can cause would be scary.

Exotic matter is just a concept which has not been proven nor dis-proven... but yet acted on as to verify mathematical constructs.

High frequency magnetics and nano wire experiments are more likely to spawn results that would be more useful as our current technology stands...

Umm...

Wrong.

I invented time travel.

Interesting stuff for sure.

It's been done.

Wrong Dr Who is the only time lord left alive. I know cause it was on the telly

Martttttttttttyyy

Damn. Time travel works. I am still alive. (I come from year 2521). However, I meant to travel to year 1990 and grab all porn domain names. I'm fucked up. How do I come back now ?

Just gotta get that plutonium :1orglaugh:thumbsup

Classic movie. I liked the first one the best.

November 5th, 1955.

That was the year I invented time travel.

No what is scary is despite that Hawkins was a below average student before his illness (hell so was many other greats), and now he works out these mathmatical theories in his head before hand with a gut reaction and then has people help him see if his theory is mathmatically correct on paper per say. That is scary.

Hell this is a dude that has rarely looked into a telescope in his life.

Interesting, but I'm afraid not fisible at the moment.

Interesting :)

Maybe one day time travel will be possible.Then again if one day it was possible then people from the future may have already visited us.According to Family Guy in the future we'll use time travel to go on vacation.
