  • Take a solid sphere and compress it.
  • The Internal High Density will cause a negative pressure (dense on the inside, pulling the outside in)
  • This will lead to an implosion.
  • The result is a black hole.

    Along with the black hole, in certain events, the black hole creation event can, with non zero probability, create a baby universe.

    Galaxies are receding from each other

    Isn’t this true of ANY explosive event (say a large firecracker in a closed room) – things will appear to recede from each other?

    Yes – that’s true. But there’s one key difference in the way galaxies recede from each other.

    It doesn’t matter WHERE your observation deck is – the recession is exactly the same. This would not be true for a firecracker explosion in a closed room. Only the exact explosion point would show everything receding. If you watched from outside the room, you would actually see things APPROACHING you – NOT receding from you.

    So, how is it possible that NO MATTER where you are situated, the recession seems uniform?

    The Surface of a Balloon

    The best analogy to date is to imagine the surface of a balloon as it blows up. As it blows up, EVERY point on the surface recedes from every other point. It does not matter where you are situated on the balloon.

    Space IS the surface

    People state this metaphor as ‘Space is LIKE the surface of the balloon…’. In reality, space IS the surface. There is no other part of the Universe (nothing INSIDE the balloon or outside the surface).

    Einstein did not have the benefit of knowing that

    a) There were other galaxies besides our own (Hubble found Andromeda in 1923)

    b) These ‘other galaxies’ were receding from us – and from each other

    Not knowing these experimental facts, Einstein postulated that there must be a non zero cosmological constant that keeps the Universe ‘static’ (not expanding or contracting).

    Enter Friedmann

    Friedmann, without having the experimental evidence himself, figured out that everything is receding fromĀ  everything else.

    How? He made a simple , yet powerful assumption, while solving Einstein’s equations.

    That the curvature that one sees is independent of where one is in the universe. That is – it is equally curved regardless of where you are. Based on this assumption, he showed that any such cosmological constant had to be ZERO.

    There’s a mystery as to why the Universe’s expansion is accelerating.

    As per all our educated guesswork, the first 9 billion years found the Universe in a decelerating mode. The last 5 billion years, has shown an acceleration.

    The acceleration is based on galaxies being pulled further apart from each other.

    ThisĀ pulling apart can be caused by Dark Energy (the opposite of regular energy).

    However, it can also be caused by something else pulling on the galaxies. That something else can be OTHER UNIVERSES (multiverses).
