I am presently reading a paper on Inflation. It uses the term Hubble length. Can someone provide the Hubble length in cm.

I am reading Michael Hines new book, Supersymmetry and String Theory. He keeps referring to "tree-level". What is this?

This is a correct statement. However, a convient rule of thumb is that between 1 - 2 % of the total mass of the launch system [satellite, launch vehincle, propellant] can be plaaced in orbit.

Gravity dominates A planet's atmosphere is 'held in place' by gravity. However, first the planet needs to be close enough to the sun so that surface temperature is high enough to avoid liquifying any atmospheric gas. The four inner planets satisfy that condition. If the temperature...

Any paper on the subject Blueprint Do you know of any papers on this subject?

new physics Both of the above comments imply that the black hole would [suddenly] expand and disappear. What is the physics for such an occurance?

Greene in "The Fabric of the Cosmos" discusses supersymmetry. On pages 264-5, he states:"...before the Higgs ocean formed, not only did all force particles have identical masses - zero - but the photons and W and Z particles were identical in essentially every other way also as well...At high...

I have read Greene's book. My basic problem with attempting to find a higher dimension is that all the arguements [I have seen] for finding a higher dimension are based on analogies with 'seeing' the effects of the 3rd dimesion in lower dimensions. Is there any mathematical studies of what can...

Do you have a reference for your statement about the 11th dimension? Particle physicists are hoping to see gravitational effects from this 11th dimension who size could be on the order of mm.

D9 not D8 I think you might mean D9. D9 would give you 'strings' and thus all the particles of the universe. D9 would consist of D3 which is the normal spatial dimensions and a D6 which are compacted and needed for the C-Y manifolds. Time would make it a D10.

Not the early universe It is obvious that the gist of my question was not clear. I am talking about the expansion of the universe reversing and compacting. This compaction should result in the 'mother of all black holes' which is probably much larger than original volume of the early...

seeing across dimensions I agree with this statement. First, our 3D world is electromagnetic {EM} in nature and EM does not exist in other dimensions. What little discussion I have seen implies that only gravity exists in other dimensions {up to and including the 11 dimensions of M...

Thermodynamics, gravity, etc The definition is correct BUT the situation for the Big Bang is different than the normal formation of a black hole. Consider the possibility that the universe could collapse. The black hole[s] created in this collapse do not collapse to an infinitely small...

Space time Einstein's theory of gravity requires that time is an integral part of space time which is 4 dimensional. True parallel motion probably does not exist in space time. Your question seems to imply a separate universe different than space time.
