i understand the big bang theory in principle...the rapid expansion of the universe etc...my question is....is this repeatable?..after a while everything will slow down...start contracting again....does it all get sucked back inward until a critical point is reached and than...bang starts over again? has this been going on for eternity...and we has humans just got the luck of the draw this go round?

I dont really understand this question, actually I have problems with the subject, any help I'll appreciate, thanks

Q: suppose that G is a cyclic group and that 6 divides |G|. How many elements of order 6 does G have? If 8 divides |G|, how many elements of order 8 does G have? If a is one element of order 8, list the order elements of order 8

What order do I do this in? there are no parenthesis so i am not sure?

Simplify. Express your answer in simplified radical form
square root of 48 minus square root of 3

I posted a question yesterday asking if there was a ghost in my house. I said that my brother saw an orb and I felt my bed shake and a knocking noise. Well last night something happened again... I felt someone put there hand on my head. My head was paralized for a minute or two. But I didn't feel any warmth or anything. It was just pressure. And now I am losing things. For instance, I got my brush and put it on my bed, I walked out of my room into my bathroom that is right next to my room to get my hair dryer. My brush wasn't on my bed, I looked all over for it. I still have no clue where it is. I swear I am going crazy! Do you think I am just imagining things? And I know my brother isn't just playing with me, he wasn't even here when some of these things happend. I am really scared!!

Here's the setup I visualize:

- light emission source;
- chamber that is as close to perfectly reflective (both with regard to light and heat) as possible;
- a tiny outlet hole at the end opposite the light emission source.

It seems that such a thing would produce at least a miniscule amount of thrust, though we lack the materials to make such a chamber. But if we could do it, would it work? Light can push against things and alter their trajectories, so I would assume it has to have -some- thrust capability.

Just curious. :-)

does the path of a molnya sattelite present a hazard to low/medium earth orbit objects considering the crossing of paths? and the much greater velocity at perehelion? do they/it have to be tracked constantly for this reason?
