Take that science!

I don't know, one of my physics teachers could bench like 250-300lbs!
and he was a physicist!

And on the traveling back in time thing, i really have no clue. I guess if we could create a machine like that though, I would totally go back 4000-5000bc and check how those egyptians made those darn pyramids!

Was that physics teacher an oilers fan by chance?

That simulation idea in the video actually sort of freaked me out.

If thats true... death truly means the end of existence, like a Sims character. What if life as we know it is some sort of extremely realistic video game developed 1000s of years from now, and every time something horrible happens its just the result of the manipulation of some bored teenager looking for a laugh? Like how you would unleash tornadoes on your Sim City or lock your Sims characters in rooms and watch them starve to death.

But that means thousands of years from now, we (as in us in this simulation game) will be developing our own simulations, so in that case, maybe we're just the result of some other simulation... of another simulation...

GAH WHAT IS REAL? I shouldn't have watched that.

Yah!
how did you know that?

Is it not reasonable to expect that if time travel was possible, it would have already happened? And we would be experiencing the effects as we speak? of course, does it not just then cause some sort of gigantic time screw loop that leaves us all in an unending spiral? of course, i could just be loaded. that's always an option too.

The Physics of Time Travel

Is it real, or is it fable? by Michio Kaku
In H.G. Wells' novel, The Time Machine, our protagonist jumped into a special chair with blinking lights, spun a few dials, and found himself catapulted several hundred thousand years into the future, where England has long disappeared and is now inhabited by strange creatures called the Morlocks and Eloi. That may have made great fiction, but physicists have always scoffed at the idea of time travel, considering it to be the realm of cranks, mystics, and charlatans, and with good reason.
However, rather remarkable advances in quantum gravity are reviving the theory; it has now become fair game for theoretical physicists writing in the pages of Physical Review magazine. One stubborn problem with time travel is that it is riddled with several types of paradoxes. For example, there is the paradox of the man with no parents, i.e. what happens when you go back in time and kill your parents before you are born? Question: if your parents died before you were born, then how could you have been born to kill them in the first place?
There is also the paradox of the man with no past. For example, let's say that a young inventor is trying futilely to build a time machine in his garage. Suddenly, an elderly man appears from nowhere and gives the youth the secret of building a time machine. The young man then becomes enormously rich playing the stock market, race tracks, and sporting events because he knows the future. Then, as an old man, he decides to make his final trip back to the past and give the secret of time travel to his youthful self. Question: where did the idea of the time machine come from?
There is also the paradox of the man who is own mother (my apologies to Heinlein.) “Jane” is left at an orphanage as a foundling. When “Jane” is a teenager, she falls in love with a drifter, who abandons her but leaves her pregnant. Then disaster strikes. She almost dies giving birth to a baby girl, who is then mysteriously kidnapped. The doctors find that Jane is bleeding badly, but, oddly enough, has both sex organs. So, to save her life, the doctors convert “Jane” to “Jim.”

For anyone interested in Time Travel, Parallel Dimensions, Quantum and String Theory and all that other good stuff, I highly recommend Michio Kaku's books. Their written in plain English for the enthusiast interested in this type of stuff, extremely well written and understandable.

I once locked a guy and a girl in a room with one communal shower, the crappiest T.V. out there, a toilet in the middle of the room, and the best bed money could buy, and they wouldn't get it on, so I walled him into the corner with a window, and a viewing chair outside of the chamber of death and took away the T.V., the girl watched him die for two days, she sat there and soiled herself instead of leaving the viewing area.

That game is sick.

Is time travel possible?

The Russians seem to think so, and claim to be only 3 months away from it! http://www.dailymail.co.uk/pages/liv...70&ito=newsnow

Time travel could be a reality within just three months, Russian mathematicians have claimed.

Although I severely doubt that such is the case. Nevertheless, it's fun to think about.

Yah.. I am excited for this to get fired up. Hopefully we don't implode into a huge black hole or anything, and everything goes according to plan and they are able to learn about it.

Horizon did an episode about it:

If that doesn't work, then just search for "The Six Billion Dollar Experiment" on google video.
