Wrong. Yes it does.
There are two movements among the galaxies. (1) A random movement, and (2) a "movement" due to universe expanding. The further away the more (2) take place in relation to (1). So other galaxy clusters are moving away from us, but within the galaxy clusters ...[text shortened]... ost important reasons that we believe that the universe is expanding in the BigBang theory.
Perhaps I was unclear at (at lest) one place:
"but within the galaxy clusters the random movement is most important in relation to us."
should rather be
"but within our galaxy cluster the random movement is most important in relation to us."

OKay---that makes sense. I hadn't thought about random movement, and with the universe being entropy (as the brilliant physiscist/comedian Robin Williams pointed out 😀 ) I should have realized that.
Entanglement just means that some certain property of a particle is related to the same property in another particle, for example you can prepare a system in such a way that if the spin in one particle is "up", the other one immediately goes "down". This is what's used in quantum teleportation, but it turns out that it does not allow any information to be transmitted faster than light. The subtlety is that if you have some observer A 100 miles from observer B, and A measures an entangled particle to be spin up, observer B cannot "do" anything with that measurement unless he knows the outcome of the measurement of A, which would need for example a telephone link.

Actually, the speed of thought is about 200 feet per second. (speed of neuron data flow)
You might be thinking of the idea we can think about Andromeda galaxy one second and think about getting a Gelati at Rita's the next, which you might translate into doing a couple of million light years per second but that is not exactly velocity, is it?

My dad often uses that as an argument asking, "How long does it take to think of the sun?". That being proof that thought travels faster than light. He doesn't seem to understand when I explain to him that your thought isn't actually travelling there. 😛

I bet he can break conservation of mass-energy with his imagination too!

Some says that gurus can defy the Newtonian laws of gravitation by levitate with the force of pure thoughts.
I believe that when I see it with my own eyes.

If there is a force involved then the law of gravitation is not violated.
Originally posted by FabianFnas That's right, thoughts isn't enough to move something. You have to put some force into it too. Telekinesi doesn't work.
Entanglement: please explain...
