    Firstly, let me explain EILITDC, Explain It Like I'm @TdC

    Now, the purpose of the thread, ask a question, and have it explained in the above manner to your satisfaction without any indepth scientific masters degree explanations.

    Here goes mine,

    If the universe is expanding, what is it expanding into?

    Christ, I am trying to understand complex questions with the most simplest of minds, ie @TdC

    I liked the question so i googled!

    It depends on what theory you hold to, if a finite universe is expanding then there must be something outside the universe it is expanding into, however as we are inside it we have no way of looking out

    If the universe is infinite then it is not expanding but stretching, so while galaxies are not moving away from each other but the space in between is stretching out (but to us on earth they appear to be getting further away)

    Still not happy. What is the universe expanding into ? What is there outside of the universe? Something must exist for the universe to expand into, so what is it?

    It creates the space as it expands...I like to think its pushing non space out of the way.

    Incorrect, this is the logic mistake almost everyone makes when they ask this question. The expansion of the universe literally creates the space it expands into.

    The usual analogy is imagine the universe being a balloon with space the surface. Everything expanding outward is then caused by the stretching of the surface. But the balloon is actually a four dimensional space-time and the "surface" is now the 3D volume of space.

    Since our frame of reference is, for the foreseeable future, fixed in this solar system, it isn't a question that can be answered. We can only view the edge of the observable universe, which for us is just over 90 billion light years wide. We are in the exact centre of that observable universe. We can only speculate as to what's outside the observable universe - we have no way of knowing how large the universe is. We'll almost certainly never be able to see beyond the observable universe and therefore we will not be able to see if an "edge" exists.

    We are expanding into the space between other universes. ;).

    Who knows? until scientists can travel wayyyyyy beyond what they're capable now, anything that is said is just speculation with no hard facts to back it up... for all we know it could be a morbidly obese alien trillions of light years a way trying to suck us all in, it could be a black hold dragging us apart which then begs the question - does that mean there are blackholes surrounding us dragging us apart in different directions.

    Summary - fuck knows.

    Be careful!! @Deebs is having trouble enough with just 1 universe. It we get onto multi-verses, Branes and M-theory I think his brain may explode. :D

    Someone mentioned knowing the math behind it all is essential in understanding and formulating the correct questions.

    This is the most practical analogy we have right now, even though I know it doesn't actually feel like it answers the question "but what is it expanding into?" That's because us 3D creatures can't visually 4D (or 5D if you treat time as 4) very easily.

    I've kind of come to terms with never being able to visualise spacetime and just accept the maths sort of works apparently.

    Well, time is an extremely intricate subject, just as an example, and according to Einstein's theories that if you would travel with an approximate speed of 99.9 something % short of the speed of light to a certain destination and back, that in your 'space time' would take 4 weeks, others would, during that 'time' experience it as a number of years gone by. According to theory.

    You should read Flatland, it's a great book that shows how hard it is to comprehend other dimensions.

    But, basically, we're expanding into a large warty vagina.

    Not theory, fact.

    The other way to think of it is that before the Big Bang there was no space or time so there is very specifically and precisely "nothing" outside the universe that was created.

    Time dilation has been experimentally proved many many times.

    Explain it like @TdC would explain it:

    "It's like this. My friendly lezza says it's expanding between her labia, but she won't show me. But that's OK, because I'm down with her not showing me. :eek: But when I'm architecting a new solution my bosses don't understand the size of my friendly lezzas labia, or the fact that my code can correct for the expansion of the universe. But she still won't let me see her flaps.

    :eek:...

    ....Mojito?"


    ...Q.E.fuck-ing-D.

    The balloon idea doesn't make sense to me because the balloon is in a space that allows it to expand.

    Also before the big bang there was "nothing" but there must have been something even if it we don't know what it is or proof that it exists.
     
  23. DaGaffer

    Hence my point that the balloon analogy falls down because you can't imagine the surface of the "balloon" isn't expanding into anything is the expansion itself.

    That's why it's an analogy and not a mathematically exact description of 4 dimensional space-time manifolds. ;)

    Why? You're trying to force your everyday experience of the world onto something that's very very far from normal. It's similar to why most people (i.e. everyone) have major conceptual problems when learning about Quantum Mechanics.

    So you are saying it's possible to remove a piece of the universe and leave nothing there?

    Imo it's balloons in other balloons. Also, Scouse is correctish. Maybe!

    On a more serious note - think of the universe as a pond... what happens when you drop a brick into a pond? ripples expand outwards, same shit with our universe I guess? the big bang being the brick obviously.

    But before the big bang there was nothing to ripple through
