No... not really. All BBT's begin with a quantum singularity where all energy and mass in the universe existed at a single point. The laws of physics did not exist at this juncture; only after expansion. Think of it the same way that evolution describes life--only after life got here. It has no explanatory power before life's genesis.-So we suspend the rules and say that it could happen even though it violates everything we know to be true, but ok, we will just skip that bit and come back to it later.->The only way it would be a straight line, is if you knew the shape--which you couldn't because it was in a quantum superposition. In that moment, just before expansion, it was simultaneously EVERY possible shape in the universe.-A straight line in every possible direction(spherical). We would be talking about a lot of particles, not one. I should have clarified in this post, but I did clarify it later. Apologies.->There was also a variation in temperatures; the temperatures that were on average lower were where quantum particles started to clump. Hydrogen and helium would begin forming and fusing after they had already "found" each other as quantum particles.-If they were in a plasma state, they would no longer be H and He, they would be ionized unbound atoms and electrons. At least according to the definition of plasma. However, assuming they did keep their structure:-
In 1948, Physicist George Gamow hypothesized that all of the elements might have been made in the hot and dense earlyuniverse. He suggested to his student, Ralph Alpher, that he calculate this. Alpher did so for his PhD thesis, with RobertHerman participating in much of the work. Alpher and Herman found that Gamow was wrong: most elements could not havebeen made in the early universe. The problem is with neutron capture. Neutrons decay in about 10 minutes, and their densitydecreases as the universe expands in that time. There just isn't enough time to keep building up to the heavier elements beforethe neutrons are gone. The heavy elements are made later, in stars. Only the lightest elements are built up in the earlyuniverse. -Concerning Anti-matter-Antiparticles are also produced in any environment with a sufficiently high temperature (mean particle energy greater than the pair production threshold). During the period of baryogenesis, when the universe was extremely hot and dense, matter and antimatter were continually produced and annihilated. The presence of remaining matter, and absence of detectable remaining antimatter,[11] also called baryon asymmetry, is attributed to violation of the CP-symmetry relating matter and antimatter. The exact mechanism of this violation during baryogenesis remains a mystery.-There is not enough anti-matter in the universe. A Big Bang would produce
equal amounts of matter and anti-matter, but only small amounts of antimatter
exists. (Asimov's New Guide to Science, p.343).->Stars didn't create the mass. They simply altered its components. I would like to see more about this argument however.-Sorry for being unclear there. Conversion is a better word. See Gamow and Alpher above.->The size if the universe is infinite. Aside from that, if, using your own scenario--the universe shot out as a straight line--there would never be a center.-Data from the CRMB would disagree with the infinite size of the Universe. It's big, but not infinite. BBT does not speculate about whats on the other side of the CRMB.
