hello,i'm new to this discussions.but hope i can join in since it's interesting.i'm doing master in physics in local U.i must admit i'm still in very basic level of physics.
come on,physics is all about basic what.
nice to meet u ppl.

"I have a thought experiment that i am too lazy to calcualate.
We all know that light speed for an object is quite impossible becuase it requires infinite energy. But here is the question.
There are 2 objects (spheres) in a vaccum.

Object A has a mass of 1Kg and is 100m away from object B, object A has a radius of 0.01m.

How much mass/density does it require for Object B to be to attract Object A so that Object A will accelerate to 99% or 100% (if possible) of light speed before it crashes into Object B."

by newtonian physics,
mass of B = 4.5e31 kg if it collides in 1 nanosecond.aprox to mass of sun.
funniest part is mass of A is not used in the calculation.correct me if i wrong.
if got time,i'll try to fuse relativity in it.
nice thought experiment it was.

can anyone tell me what is quantum mechanic actually?cut the jargons.
tell in common words so layman also can understand.tq.
