    creating a universe in the lab do you think it's Physicaly possible possible?

    if so what would it take?

    my theory would be concentrating a huge amount of energy into a particle suspended in vacuum.

    I don't know if it will ever be possible to create a Universe in a lab. I'm sure it will be possible to create aspects of it, (ie, a singularity) but creating an entire universe unto itself would just kind of a messy issue, no? At the very least, it would create BIG trouble for people in the immediate area of said universe, taking into consideration the idea that universes have to tendency to expand at incredibly high rates of speed.

    For one thing, even though it might be possible to create a singularity, a "point" of infinite density, we still don't know what "caused" the universe to change from being a singularity (time before the big bang) into the Universe (time after the big bang). What made the alpha point "decide" to stop being what it was, and become the expanding universe? And why then? Why not a million years before? Why not six weeks after?

    What event took place that determined that the Universe should begin *now*, at this measurable time, as opposed to any other time? In other words, if you can create a singularity in a lab, what would you (or could you) do to it to make it suddenly decide to make itself into a universe?

    that would be a problem.

    apparently the temperature back at that point in time would have been tremendous to say the least. we all know that heat causes particles to move around faster, i would have thought that particles becoming super energised, in a dense state like that, would have created some sort of push on the walls of the universe causing the expansion.

    just a theory.

    What event took place that determined that the Universe should begin *now*, at this measurable time, as opposed to any other time? In other words, if you can create a singularity in a lab, what would you (or could you) do to it to make it suddenly decide to make itself into a universe?
    mesurable time breaks down near a singularity so it might have happened at some other time and the universe would never be any the wiser.

    just another version of our universe.

    the universe is somthing we can influence, and something that influences us. Everything that can be measured.

    then it's not infinite since it can be measured?

    From what I've been told in the theoretical context I've forgotten, baby universes may by budded routinely with no measurable effect.

    The universe's implied infinite size is do to the fact that satellite data has confirmed that the universe is flat.

    Creating an artificial universe perhaps, but not in another universe. Any expansion of the universe is subject to progressive acceleration. If you create a universe within another universe, the speed of its expansion will be much bigger and it will destroy the original universe. Theoretically it is possible to create the universe, and within another universe, but this would lead to undesirable consequences.

    From what I've heard at least, some of the math shows that a new universe would not destroy the existing one. It would pinch off and become it's own universe somewhere else with no connection to this one.

    That stuff is all speculation. The mathematical models are full of holes.
