Want more mind-blowing science?

Several of you asked me for the links to the video I showed in class and to the TED talk mentioned. Your excitement about this is exactly why I choose to be a teacher. Even if you don't understand everything, understanding a little bit may lead you to learning more, and more, and more.... Additionally, you wanted "PROOF!" that the time travel experiments are real. You are wise to question the validity of these assumptions. Here are more documents for you to enjoy.

Time Travel Simulation Brief and here is the information I mentioned, which Eric and Jordan Liban explained to their blocks.

Both the general and special relativity theories have been proven with GPS satellite technology that has very accurate timepieces on board. The effects of gravity, as well as the satellites' increased speed above the Earth relative to observers on the ground, makethe unadjusted clocks gain 38 microseconds a day. (Engineers make calibrations to account for the difference.)
In a sense, this effect, called time dilation, means astronauts are time travelers, as they return to Earth very, very slightly younger than their identical twins that remain on the planet.

Here is the link to the full article where I copied the above information: Time Dilation

The original experiment write-up  This one is too technical until you get farther along in understanding the science and math, but I included it to show you it really does exist.
