If you can survive lava-like temperatures there is another issue for the well-being of Miller's planet from Interstellar. Time passes on the planet 61000 times more slowly than for an observer far away from the black hole. From this analysis: Einstein's laws dictate that, as seen from afar, for ...

I don't know quantum mechanics and know a little bit about mechanics and a very little bit about subatomic particles but I am just a curious to know the answer to my question. My question is if 'inertia' is unwillingness to of an object to change its state of rest or uniform motion then can I say...

If perfect rigid bodies were to exist then,consider a scenario in which two rigid bodies of equal masses moving with velocities of equal magnitude but opposite in direction colliding against one another.During the collision,velocities of both the masses will decrease and it will reach zero for bo...

My main source of confusion is the following. Suppose I have a scalar potential $V(x,y,z)$. The electrostatic field for this potential is $-\vec{E} =\vec{\nabla}V = \frac{\partial{V}}{\partial{x}}\hat{x} + \frac{\partial{V}}{\partial{y}}\hat{y} + \frac{\partial{V}}{\partial{z}}\hat{z}$. This is...

Is it true that both work on the same principle of operation: the interactive fission chain reaction U 235/Pu239 and the bombardment of Uranium-235 by fast neutrons produce a fission chain reaction accompanied by a enormous thermal energy in addition to beta and gamma radiation? The most probable...
