sin(thetha)*2=1/(gamma2)*2-1/(gamma1)*2
where gamma1 and gamma2 are the lorentz factor of the respective particles

for example:Two light bodies in the orbit arround a much more massive one.You should be able to reproduce simple orbits.
-Two heavy bodies in close orbit with a light body orbiting them both .You can investigate the beheaviour of the light body as a function of its position relative to the heavy bodies.,and identify the lagrangian points.
You have to write the codes in matlab.

A negatively charged particle with charge - q is far away from a positive charge +Q that is fixed in place. As -q moves closer to + Q, does the electric field do positive or negative work? How about if the charges are the same (+ +) or (- -)?

I know these:
- Objects that get really big with lots of gravity cannot support their framework and so the object just eats big bites out of itself until it and the surrounding material plus its color and its light are no longer visible.
- Stuff goes toward the imploded object which is smashed into a negative nothing. Yet it exists as a something because it effects other things. Or maybe these other things are just the excess fat of nothing?

What I want to understand is why are galactic jets shooting out of the rear-end of black holes? Are they shooting out? They look like it. And what are they made out of?

If black holes consume light, could it be that dark matter is matter that is being blocked to us-- the observer-- by a black hole(s) that is between us and the "dark matter"?

Could we be in a black hole, as we speak?

Two blocks on a horizontal frictional surface, and the coefficient of kinetic friction between each block and the surface is 0.1, what would be the acceleration? what would be the tension in the string?

The picture looks like:

[5.47 kg]---T---[19.5 kg]---48.8 N--->

The [ ] areas are the blocks.
The ---T--- is the tension.
The ---48.8---> is the force.
Acceleration of Gravity is 9.8

Is there a speed of gravity, or is it timeless? Two objects attract each other. But what if I move one of them(With a high speed)? Does the other object respond imediatly, or does it have a response delay? Just like we see stars on the sky, that aren't even there anymore, because of the speed of light.
