Hai..
One 'parsec' is the distance from a star which makes an angle of 1''(1/60 of a degree)with the sun and earth(1.5*10^8 km).So by measuring an angle of 1'' we can measure to a maximum of 2 parsec.
But this only about 7 light years and we are speaking of much much bigger astronomical...
Don't know velocity
I tried it without knowing horizontal velocity.If I know that it is very easy as u said.I asked for some kind of geometrical methods for calculation,by comparing two parabolas made by falling balls.But now i think it is not possible.
Thank you.

We say all forces can be explained as the exchange of particles.
Thus gravity as the exchange of gravions.Since nothing can travel faster than light how can we experience the gravity of a black hole
outside.

Hai all,
In projectiles the horizondal component of their velocity remains constant and veritical compont changes as it gets accelarated.So with this, I think we can find an experiment that gives the accelaration due to gravity(g) without a clock.i.e if we are droping a ball from a...
Hai friends..
We are getting enough data on speed of gravity.But what about
the speed of other mechanical forces.
When I am pulling one side of a long rop how much time will
it take to reach the othe side .I don't know, may be the speed of wave.
I think if I pulls an...
Hai friends
I think we are not considering the relativistic effects here,then i think accelaration is absolute.If we measure the instantanious velocities of an accelerating thing from two frames of references indeed they will differ.But in difference of velocity after some time both...
