If Mars used to have a denser atmosphere in the past, could Earth have had one as well?

Does anybody know if it is even possible for a planetary moon to have a moon of its own orbiting it?

Cepheid Would say a cepheid variable star in a galaxy moving at 150,000 mps away from us appear to blink slower and how would this slow blinking, if so, be related to the redshift at which it was detected?

Yes that is probably correct.

If quasars are appearing to travel at almost the speed of light from us, what would the relative time frames between us be.

But will it be directional without lasers?

Well, there goes my idea for interstellar probe communication. :)

Are these Masers radio frequency? THought it might be easier to use a radio laser to communicate from space probes and such. a tighter beam aimed at the Earth you know rather than all directions.

Has anyone created a radio laser, if not why not if you know...

In that case, could there be enough neutrinos orbiting the galaxy to account for some "dark" matter?

Thanks you for your reply, I meant within by which a neutrino can pass through mass without likleyhood of collision so a neutrino in an eccentric orbit could pass through the sun on part of its orbit perhaps.

I hear that the moon is steadily moving away from the earth. Is it due to the suns gravity? Will it eventually go out of Earth orbit and circle the sun on its own? Would there be any chance of a posssible collision with Earth if this happened or would it leave Earth orbit at its closest...

Does this mean that neutrinos could be orbiting within a large enough mass?

Does a black hole bend the space that photons travel in so that they are bent towards it? How would gravity attract a photon if they have no actual regular mass? Also, are neutrinos attracted to black holes and sucked in (theoretically?)

Short story There is a short story by Gardner Dozois called I believe "A Kingdom by the Sea" It talks a great deal about a slaughter houses and used to be posted on the scifi.com website. It was published in 1972 I believe. Its worth a read.
