Thanks, all! I really appreciate the feedback...

A brief question: I am an armchair cosmologist - or maybe a "wannabe" cosmologist...it's a fine line. I am 47 years old with most of my career in software behind me but, without returning to college to become involved professionally in Astrophysics and Cosmology, I'd like to contribute to the...

Great information, Marcus. Thanks so much for your patience with my armchair cosmology.

I understand your response - thanks a bunch! If I could add another related question (please let me know if this should be another thread): The universe, if taken on a very large scale is essentially homogeneous (isotropic). The distribution of matter/energy is uniform - and I contribute my...

@marcus - Give me a bit to read the rest of your message. I posted reply #3 before I was able to read your entire post. My apologies :-)

Thanks, marcus - that figure might take a while to assimilate. I'll work on it - but, in the meantime, consider 2 observers sitting on planets whose cosmic horizons don't currently overlap. Depending on how far apart they are, space itself may be expanding faster than the speed of light...

I was reading The Elegant Universe a few days ago, and came upon a passage (p.40) where Brian Green states "Over time the size of the cosmic patches laid out in Figure 2.1b will increase; with more time, light can travel farther and so each of the cosmic patches will grow larger. Ultimately...

With the recent experimental evidence that the Higgs boson likely does exist, and that the Higgs field may well be responsible for "giving" mass to all matter, I am curious how we theorize what gives the Higgs particle it's own mass. Warning: I am not a physicist so be gentle :-)
