A good way explaining how two people can be right at the same time.

It took me an hour to get it but yeah
I unstand but it does all make sesnes Question

Yeah it's the famous einstein relativity theory. Quite interesting. They are actually working on a time machine thats based on that very theory.

What they are trying to do is send a subatomic particle down into a "whirl" of laserlight. The subatomic particle will be "grabbed" by the light and "stirred" in the speed of light, thus sending it back in time Smile

Yes!! i've seen that! It's very interesting, I was explaining it to my dad the other day actually. I'd be interested to see what happenes when they turn it on!

I don't think it will work. See this link:

Could be difficult to build something which needs an infinite amount of spacetime or a ring much larger in circumference than the observable universe.

That simultaneity video is very intriguing, but doesn't it conflict with Einstein's theory on relativity and speed of light?

I thought according to that theory, speed of light is suppose to be constant to ANY frame of reference, that is the speed of light is constant and does not appear faster or slower if you're standing still or moving at the speed of light itself. If an observer moves at the speed of light toward a light beam, the observer will see the light beam approach at c, not 2c. Physicists have done many experiments to prove this is so, I don't know how or what experiments but I do know that they've proved it somehow.

So with that being said, in that train example the observer on the train should still see both bolts of lightening at the same time, even though she is moving forward. However, according to the theory, it's actually time that slows down for the observer on the train.

Hi guys very interesting stuff ,
but i think my wife must contradict Einsteins theories ,well we were out shopping and she opened her purse and a coin fell out ,and she bent to pick it up ...and it landed on the back of her neck ...now tell me about speed lol
