    I was thinking, instead of a big bang, why couldn't there be a Big Expansion? This Primeval Atom could have just expanded, and continued to expand, and the larger it gets, the less it expands.

    Has there been any information on this, or are scientists just stuck on "Oh yeah, we came from a huge explosion, mhm. That's it!"

    This would give more ideas on the spacetime theory in my honest opinion. I am still working on ideas, this is just a quick thought process topic mostly.

    Anybody have any ideas?

    What's the difference between a big bang and a big expansion?

    Scientists don't think that way. There is no good model about the state of the universe at time t=0. The "big bang" theory describes what happens after. The name "big bang" originated somewhat as a joke and it stuck. However there is nothing about it which calls it an explosion.[/quote]

    Rather than a joke it was Fred Hoyle, proponent of an expanding steady state universe, who introduced the phrase to deride the primeval atom concept. It was sarcasm that the supporters of the theory deflated by adopting it for themselves.

    Actually, Black Sunday, the best theory is of an inflationary universe as proposed by Alan Guth. So scientists are considering a big expansion and it seems that the larger the universe gets, the more it expands. The Dark Energy causing the expansion may be the energy of space time itself. The more space time you get the greater the expansion.

    Also, the Steady State theory proposed a universe that did not expand or contract (hence, was steady) but was continually remade over the eons by the spontaneous creation of hydrogen atoms at a scale that would be imperceptible.

    Expand or explode an explanation of how and why it compacted is needed. Science is not willing or able to view beyond demonstration. I do not believe t = 0 is pre-big bang. All that is needed for time to exist is energy. Pre-big bang all matter is compressed which takes and holds a massive amount of energy.

    Incorrect. The theory accepted expansion. New matter was created as part of the process of that expansion.

    Ok, the makings of all matter, still takes energy or it wouldn’t have big banged.

    If it was merely standard expansion, that would be in three physical dimensions so everything could be traced back to a starting point, and essentially the universe would be a thick shell with a hollow centre, everything having moved away from that point.

    The BB needs expansion in four physical dimensions, a hypersphere, as in dots on the surface of a balloon where they get further away from each other (in the universe, gravity would hold clusters and local groups of galaxies and stars together.)

    The speed of expansion was said to have increased several billion years ago, which is what you would expect as the objects were further away from each other, so less pull on each other, but it is said to be down to dark energy.

    If our universe is hot, then the atoms moving faster and maby expand our universe
