A few questions:

1. Why do the equatorial winds blow from east to west? Is it because the
earth rotates from west to east? So then, does the earth's atmosphere not
move with the earth's lithosphere?

2. Is there evidence of gravitational lensing caused by dark matter?

3. Does gravity act on massless particles such as photons? If so, is there
a reason? I don't understand the concept of "effective mass." How can
gravity act on effective mass?

4. Do you have recommendations for a good introductory book to general
relativity?

Thanks!
Jhumki
