Fascinating reading for those who enjoy science.

    Interesting Dennis.

    I was watching “The Terminator” the other day and thinking how on Earth something could travel in time. (Theoretically speaking.)

    Then I realized that The Universe isn't unfolding in a linear fashion. Instead of thinking about it like “A - B” it’s more like “A+B+C”.

    (That probably doesn't make any sense by the way. ;-)

    • Are you saying dimensionally as well? A= Spatial location, B = "time" C = Dimension.

      I'm very fond of that idea myself. I believe "real" time is something that is just a bleed over to us "down in the 3rd Dimension" from the higher dimensions. That's why we can't perceive of it in any other form but linear. I believe light and electricity are bleeds as well.

  • It still begs the question; What was before the Big Bang?

    • Dimensions. Matter being shot into the third dimension from higher dimensions. I believe in multiple universes. The third dimension is not much different to higher ones than the second is to us, I would think.

    • There is actually a very good answer to that.

      Nobody knows, and it doesn't matter.

      The BB theory says that for all intents and purposes, the universe as we know it started decisively at that moment, 14 billion years ago.

      It is entirely plausible that there may have been an infinite number of previous iterations of the universe before, possibly even with very different set of physical laws. But when they collapsed under their own weight, they were completely replaced with another universe. And another. And then another. After each collapse, there is a new big bang, then an expansion, then a contraction and a collapse. And the cycle repeats.

      And now, our universe is the only one that matters. And, it is entirely possible that a day will come when our universe stops expanding and begins contracting. That contraction will last many billions of years, picking up speed until our universe has collapsed into itself.

      And then another big bang will occur, followed by an expansion, and possible life that will look to the stars and try to contemplate our existence.

  • Reqarding the sphere circle theory, wouldn't it make more sense if it were a SERIES of circles, like on a Computer Assisted Tomography(AKA CAT scan) machine? If they saw a single circle, they would be missing SO much.

    • I've come on here today and so far I've looked through a thread with men wearing skirts and women built like Arnie and now this brain bender.

      I think I might have to have a lie down.

  • "Concepts of the Universe

    First hour guest, author and theoretical physicist Alan Lightman talked about different concepts of the universe. There may be lots of different universes, and we just happen to be on one that allows life as know it, he remarked. The Universe has a temporary quality, with stars burning out, and everything eventually fading away, which contrasts with human beings' longing for permanence, he continued. Lightman also discussed the notion of a 'gargantuan' universe-- our telescopes have picked up light from galaxies that are so far away that its taken billions of years for that light to travel here."

    Lightman (Light man - interesting name for this topic) is an MIT professor. Guest on CoastToCoast. Before I fell asleep, I heard him say that there may be more than one universe and universes won't collide because they are in their own time zones.
  • I've been wondering, for about two weeks now, if time would exist at absolute zero. Zero movement and nothing changes. Nothing alive to perceive time. No electro-magnetic radiation given off by anything, of course.

    • Since matter is just a clump of vibrating energy, I don't think that anything could exist in a true state of "nonmotion". It would have to be an empty vacuum for time to not exist.

    Time is a direction in space.

    I still believe the universe has a beginning in real time, at the big bang. But there's another kind of time, imaginary time, at right angles to real time, in which the universe has no beginning or end. - Stephen Hawking Source: Stephen Hawking and the No Boundary Proposal
