How much energy is stored in the magnetic field of the earth?
As the magnetic field itself is always changing, would it be possible to harness that energy with a stationary coil?
How big would the coil have to be to produce a useable energy?
This may be more philosophy than physics but what you said makes sense assuming what I said is true, that light exists simultaneously everywhere along its path as if there is no such thing as distance, space or time. In other words in the photons POV there is no POV because spacetime hardly...
Thanks for all the replies. I admit I have not had any formal education regarding GR and only undergrad classes regarding SR. Other than that I was basically going off intuition.
Is it generally understood according to SR that a photon simultaneously exists everywhere along its path i.e. that...
I'm afraid your rebuttal leaves something to be desired. Would you please enlighten me with your understanding of the 'warping of space' and how it differs from my illustration thus far?
What I mean by 'warping' is that as one person accelerates, his reference frame (both space and time) lose continuity with that of his initial reference frame (perhaps his twin who stayed at home).
It is almost like you are becoming 'distant' but by a dimension distinct from those we normally...
Thanks
It appears my calculations are different than those, but I think I understand the concept at least.
Mostly I wanted to point out that it is possible to travel to distant star/galaxies within a reasonable time (from the traveler's POV). This doesn't seem to be understood by the...
While SR states one can never measure a velocity greater than C, for all practical purposes one can travel 'faster than light'. Here is what I mean. . .
Lets assume I have a Spaceship with the means of constantly accelerating at 1G. The fact that this is technologically unfeasible is...

QM simply states that the possible energy levels of an electron are 'quantized'.
The electron must have an energy that is an integer multiple of its 'ground state' energy, its lowest possible energy. If the electron were to have zero energy it would not exist. Thus the energy of...
It may also be interesting to note that if you could somehow manage to achieve light speed, time would stop for you, and it would seem as if you were traveling instantaneously, even covering large distances in an instant.
In Your point of view your velocity would be infinite.
(This may...

interesting, I have never heard this theory before, and don't understand how it fits with relativity
