comment Are gravitomagnetic monopoles hypothesized?
@BenCrowell: I gave a quick informal physicist's proof of positive mass in a question: it requires only the weak energy condition--- the positive mass is a requirement that distant black hole's area increase upon absorbing the configuration. A pure monopole is forbidden by positive mass, because it must have a mass, and therefore a regular mass. Birkhoff's theorem is not sufficient, nor are no-hair theorems, because a monopole field is not necessarily spherically symmetric, and it must not come with a horizon.

comment How can we deduce the relation $m = \frac{m_0}{\sqrt{1-\frac{v^2}{c^2}}}$ between relativistic mass and rest mass in special relativity?
@DImension10AbhimanyuPS: No, a continued fraction is when the infinite nesting is in the denominator--- yours is in the numerator. Expand out your formula, you will see.

@DImension10AbhimanyuPS: Yes, that formula is correct, but it is not the sum of your infinite series--- you deluded yourself in the manipulations into thinking you got the right answer. The actual power series for ${1\over\sqrt{1-v^2}}$ is 1+v^2/2 + 3v^4/8 + 15v^6/48 and so on, the general term is (product of first k odd numbers)/(2^k k!). Your thing gives coefficients of 1/2^k, it is not the same power series (check it carefully). When you know what you're supposed to get in advance, and you are sure the argument is correct, it is easy to delude yourself, you don't check carefully enough.

comment Why is there a deep mysterious relation between string theory and number theory, elliptic curves, $E_8$ and the Monster group?
@DImension10AbhimanyuPS: With someone as young as you, people will just assume you don't know anything, so just make sure.

comment How would a Lagrangian be used to recover the Schrodinger equation?
Oh, then it should be a comment, not an answer. Once you know what the question is asking, then you give an answer.
