1. Distance=velocity*time (r=vt)

2. E=hv

3. j*=ot

4. F=G*m1*m2/r^2

Also, is the Newton's Theory of Universal gravitation affected by General Relativity?

However, Lorentz transformations are a feature of special relativity. General relativity is not so simple.

Oops. I meant it to be j*=ot^4 where j* is the power radiated and o is sigma, the stefan's constant.I'm not sure what your third equation is...

So [tex] F=G\frac{{m}_{1}{m}_{2}}{{r}^{2}}[/tex] is changed in General Relativty also?However, Lorentz transformations are a feature of special relativity. General relativity is not so simple.

Thanks....the first one is obviously changed as the time is modified. The second one, I assume you mean [itex]E = \hbar \omega[/itex] which is also modified because the angular frequency is modified. This causes red/blue-shifts. Newton's law of gravitation is modified as well because of the length contraction.

So, [tex] F=G\frac{{m}_{1}{m}_{2}}{{r}^{2}}[/tex] is changed in General Relativty?General RelativityreplacesNewton's theory of gravitation.

Yes, it no longer makes sense to speak of forces in GR.So, [tex] F=G\frac{{m}_{1}{m}_{2}}{{r}^{2}}[/tex] is changed in General Relativty?

But in modern physics, string theory does talk about gravity as a force, right? And in string theory,Yes, it no longer makes sense to speak of forces in GR.

[tex] F=G\frac{{m}_{1}{m}_{2}}{{r}^{2}}[/tex]

is still correct right?

Thanks. I have also read the paper itself but I can't really find his equation for the Gravitational force...

What paper are you referring to? There is no relativistic equation for gravitational force, because gravity isn't described as a force in relativity.Thanks. I have also read the paper itself but I can't really find his equation for the Gravitational force...

Are you maybe talking about an equation describing tidal gravitational forces?Thanks. I have also read the paper itself but I can't really find his equation for the Gravitational force...
