There are other problems with a 2D world. Such as an inability for there to be gravity in a vacuum (at least according to General Relativity).
Or you could have an imagination.
It doesn't change the result. If you like you can say the potential energy at the surface of the Earth (r=6400km) is zero. In this case U =...
I was under the impression that a Dark Star was a hypothetical object proposed in the late 18th century from which light could not escape because it...
FxS is the formula for a constant force. If the force varies you have to sum up the force at every point by an infinitesimal distance. You do this...
Your answer is incorrect. Even if you don't want to directly use integration there is a straightforward way of calculating this. You agree that...
Since the gravitational force has infinite range, a particle only escapes the gravitational force of another particle if it is an infinite distance...
I think his argument was that a superposition of gravitational fields is energetically unstable so the lifetime of a superposition of states should...
It could possibly rule out the objective collapse hypothesis he proposed where he posited that it is gravitational fields which cause the...

Imaginary and complex numbers are not useless, they are used extensively in Maths and Physics. Obviously it doesn't matter whether you call it i,...
Remember that in special relativity you can only speak of the relative velocity of two reference frames. So a more useful way of thinking of it is...
This is a completely circular argument. The 'probablistic nature of quantum reality' is a feature of some interpretations of quantum mechanics. You...
Can you point to any experimental data which excludes Pilot Wave Theory? If you can't then I don't see how you can claim that it is what the...
Why should they necessarily accept those things when theories can be constructed which don't have the contradictions of the Copenhagen interpretation.
Considering gravitational radiation either from orbital decay or distant supernovae is so weak when it reaches Earth that it will require incredibly...
Look Ted Grant was a reasonable Marxist but he really knew nothing about science apart from the fact that it's theories had to be compatible with...
How are other posters on the forum capable of stopping other posters working out some Lorentz transformations?
Cosmological models are very sensitive to the density of the universe and any sensible model will have a density orders of magnitude lower than that...
The matter density of the universe is about 10^-30 g/cm^3. That is pretty empty. Obviously there are dense regions/objects but the interstellar...
