I was reading a book which had some comments on EPR paper (Einstein, Podolsky, Rosen - 1935) like following: In Newton's physics, when two identical billiard balls hit each other head-on, bouncing off in opposite direction, knowing one ball's position and speed will also indicate other ball's...

About slit experiment video in post 50. As delta X becomes smaller and smaller the delta P becomes larger and larger. But why does it do so in direction exactly perpendicular to slit? Why not in random directions to form a circular spot on screen?

Alright, I did not pay attention in physics class long back :) I just searched more, and guess what I found? Why does the Moon orbit the Earth rather than the Sun?

I mean resultant/dominant effect. I agree that this may not be appropriate term in physics. As you already answered OP's actual question i.e. The gravitational force on the Moon toward the Sun is about twice that toward the Earth, I read the question as "why does moon orbit the Earth instead...

And other answer is "You are at the center of your observable universe".

See this wikipedia article on Hill Sphere. Moon is closer to Earth therefore its gravitational influence on Moon is more than that of Sun.

Check out colors of stars in Orion.

To err is human, to blame it on somebody else is even more human.

Yes, clocks up in satellites do tick faster. From wikipedia (Gravitational time_dilation Outside a non rotating sphere): the fast-ticking observer is using Schwarzschild coordinates, a coordinate system where a clock at infinite distance from the massive sphere would tick at one second per...

According to this discussion, matter falls in central region because of loss of angular momentum after interaction among the particles, but dark matter does not interact so there is no loss of angular momentum. Angular momentum is result of particles interacting with each other (Bouncing...

About 4: We can see CMB in all directions because big bang happened everywhere. About 9: Around 380000 years after big bang, event called recombination occurred that allowed free flow of photons that we now see as CMB. At the time of recombination our current observable universe had radius...

Can dark matter pass through a black hole as well? Or is it trapped inside even horizon?

Any local concentration of dark matter and matter may result in such movement similar to simple harmonic motion. But dark matter must be everywhere around center of galaxy, and dark matter is estimated to significantly more than matter, such motion may not take place. If it does happen, at the...

Probably coma berenicids.

From wikipedia: Some simple, relatively uncontroversial definitions of time include "time is what clocks measure" and "time is what keeps everything from happening at once. I think you are asking whether time is absolute/eternal i.e. it existed forever, regardless of existence of matter...
