    I Question about Two Clocks in this Relativity scenario

    I have been enjoying learning relativity from the book "A First Course on General Relativity". I came across a somewhat confusing experiment mentioned in Chapter 1.8, which I have attached here: Namely, I am referring to how you might measure ##t=0## as "the difference in readings of two...

    I When did the consensus on the maximum recession speed in cosmology change?

    In the last chapter of Schutz devoted to Cosmology, Schutz writes So it seems that in 1985 it was assumed as obvious that the recession speed could not exceed ##c##. The consensus seems to have swiftly changed. When did that happen? Was it debated at all?

    I Is this just a typo in Schutz' book on General Relativity?

    I'm wondering is I'm missing something, or this should be " a non-zero component"?

    A Some questions about the derivation steps in the Gravitational deflection of light section in Schutz

    In the screenshots below there are the equations (11.49) and (11.53). I don't understand how did he derive equation (11.53) from Eq.(11.49)? From (11.49) I get: ##d\phi/dy= d\phi/du du/dy = (1/b^2-u^2+2Mu^3)^{-1/2}(1+2My)##. It seems he neglected the ##2Mu^3## since ##Mu\ll 1##, so ##y\approx...

    I Inquiry about a derivation in "A First Course in GR" by Schutz

    on page 269 it's written in the second edition of Schutz's textbook that ##(10.69)p_c/\rho_c=\beta (2-5\beta)^{-1}##. Demanding that this be less than ##1/7## gives: ##(10.70) 0<\beta < 1/6## Now, if I am not mistaken on page 268 in equation (10.57) the condition should be ##p_c/\rho_c >1/7##...

    I've been going through Bernard Schutz's A First Course in General Relativity, and I'm hung up on his "proof" of the invariance of the interval. At the beginning of section 1.6, he claims that he will prove the invariance of the interval, and after a few lines shows that the universality of the...

    GR Schutz: Why r Must Decrease in Black Hole Section?

    Schutz states in his book in the black hole section that: At r<2GM, r is a timelike coordnate, while t has become spacelike: even more evidence for the funniness of t and r! Since the infalling particle must follow a timelike world line, it must constantly change r, and of course this means...

    Hello Everyone, I am working through Schutz's A first Course in General relativity.
