Now what about this: When you walk is it you that is moving, or the rest of the universe? :D (in reality you both move, because of action-reaction. Only the Universe does not move in a way anyone can meassure with our technology)

But now we have this. Quantum entanglement. And it is possible because the speed of the interaction between the particles is Zero. http://www.abc.net.au/news/2015-10-22/einstein-was-wrong3a-spooky-entanglement-is-real/6876262

#2 That is not entirely true, because even though particles can change state at distance at what looks like faster the light travel, it really doesn't.
For one, no actual information is transmitted and no laws are broken. Further more, we should remember, that showing some kind of experiment, that behaves in contradiction with know laws of physics, does not invalidates them.
Perfect example is gravity and laws of motion, it works perfectly for planets and ships in orbit and even apples, but it completely breaks down at subatomic levels.

Here are some good explanations:

As for the video, for me best thing to take from relativity is forward time travel. Just get in a ship, travel with speeds close to a speed of light for few months, get back to earth hundreds if not thousands years in the future :)

My dad explained me that as kid in a simpler way.
"If you are far away moving faster then light and got a telescope to look back, you will see the past"
Never understood that..guess my dad was a smart man..

And of course i had to think of superman..spinning around the world to spin back time.

But it means time travel is possible..but just to the fututre..1h flight and and years will pass on earth...flux capacitor is needed to return

this doesnt explain much to me :)

the difrence in time they are talking about is just the time that information has to travel to the observer
so time is time and it will always go at same speed

if you would get real time information from the ship it would be the same, but since we are waiting for light to bring us this information and that takes time
it takes 8 min to get light from the sun.
closer less time further more time
and this is the difrence in the speed of clocks.
so we have distance d1 in meters and distance d2 and c speed of light in meters per sec
if we devide these numbers we get sec
d1/c +- d2/c
simple as that

This is one of those videos I will end up watching again and again...I liked the way everything was explained and also the background music.

If you are in a vehicle traveling at the speed of light and you turned your lights on, would they do anything? The speed of light is approximately 186.000 mph per second but what is the speed of dark. As the days get dark earlier in the winter this would suggest that in the winter dark gets to us quicker than light so therefore in the winter the speed of dark is quicker than the speed of light but hamsters run around their wheels slower in winter than in summer (and in the opposite direction, which I bet most of you didn't know) the hamster wheel spinning pheromone which is attractive to badgers and increases the ripening speed of pomegranates balances out the speed deferential of light and dark and stops Einstein looking like an idiot. :|

My theory of evolution is that Darwin was adopted 8-)

So much bullshit..... Light has nothing to do with time... and time is an abstract construct, not a real thing. Einstein is turning in his grave :(

Once I left a party in the early morning hours. I was hungry, so I grabbed a few cookies in the kitchen. What I didn't know was that these were specially flavoured cookies with a considerable amount of weed baked into them. I was drunk, so I thought they just tasted funny, and gulped the whole lot down.

I had to drive about 70 kilometers home. As soon as I hit the motorway, basic things like time, speed and distances started to distort in a funny way. Now I was the still center of the universe, and the only way to get me to my village was to turn on the throttle, so my bike would gradually suck up the portion of the planet in front of me, until eventually I got to my village. That night I had a guardian angel, because I got home without hitting anything.

Watching that movie somehow reminded me of that night.

I felt sorry for Sara at first. She has to deal with all the "inconsistencies", while Adam enjoys so called regular ride in his spaceship... But then Adam got the worst (im)possible whiplash the universe has to offer... =P

... and no one noticed that the clocks had 13 digits?
in my universe, all the clocks have 12 number :S
