If our universe began as a singularity, that 'object' would be the densest matter imaginable. Assuming uniform expansion from a point (unlikely) for millions of years, wouldn't we "see" in that period a huge, dense, expanding, solid object? Wouldn't it take billions of years for the universe to thin out enough to create hydrogen?

Isn't it more likely, therefor that stars are not the result of 'congealing' hydrogen (or black holes) but rather of solids expanding to a stage where they "burst into flame"?

Could dark matter be matter that has not yet reached this level of "volatility?"

Use mathematical induction to prove 2 + 4 + 6 + … +2n = n2 + n holds for all positive integers. This is what I have but is not proving true. I am hoping somebody can see where I am going wrong. Please help!!

The base case is n = 1 so 2 = 1^2 + 1. Assume that the statement is true for n = k. 2 + 4 + 6 + … + 2k = k^2 + k. Show that the statement is true for n = k + 1. (2 + 4 + 6 + … + 2k) + 2(k + 1) = (k + 1)^2 + (k + 1). Substituting (k + 1)^2 + (k + 1) for (2 + 4 + 6 + … +2k), we obtain ((k + 1)^2 + (k + 1)) + 2(k + 1) = (k + 1)^2 + (k + 1).

1.A mammal uses only 1-2% of its energy in ventilation while a fish must spend 15 % of energy to move water over gills. Explain huge difference in efforts to collect oxygen.

We study stars because we can see them. We are beginning to find evidence of planets. But most of the universe is made of "dark matter.' Does any testable evidence insist that it is a function of the Big Bang? Does it move in tandem with other celestial phenomena? Is background radiation any different in the presence of dark matter? Does it have any antimatter properties?

Now don't get started on "parallel dimensions." I mean simply that it is possible to imagine a "megauniverse" that includes but is not limited to the expanding matter available to our perception. (Since we are 'inside of" and "made of" our universe's matter we are, at present, limited by E.

[By 'universe' I mean simply an explosion of matter from a singularity into a vacuum. (Perhaps the vacuum surrounding the singularity has been 'vacuumed' of all matter by a gigantic black hole that resolves into the singularity.)]

However, there is no reason -not- to believe that our singularity might be one of many in various states of expansion or contraction. Hard to prove. We can't 'see' outside our universe. Still, could "dark matter' be evidence of interpenetrating universes? I'll ask that question elsewhere.
