We can't make infinite energy and CERN functions, therefore your statement is false.
    CERN doesn't accelerate the particles to the speed of light, so it doesn't need infinite energy. The reason you need infinite energy is because the mass of an object increases as it gets closer to the speed of light, so the force needed to accelerate it increases also. The slope of the increase grows to the vertical as you approach c, making the energy requirements infinite.

    Just because CERN gets within a few percentage points of the speed of light doesn't mean we can get those particles all the way there with enough energy.

    Oh, it will be a billion times a billion times a billion times a billion times more.

Thus somehow these particles travel faster than light. Additionally this limitation around the speed of light is based on your velocity equaling the speed of light. That is why in science fiction currently all means involve side stepping this. Like a warp drive. You're not moving, space around you is moving. Or using a technique to warp space time to fold it and create a worm-hole that you travel between (turn your 4 year journey into a 4 mile trip). Some are currently more far fetched than others. In the mass effect franchise the mass effect relay's creates a bubble around your ship and the bubble lowers the mass of things inside the bubble to zero thus avoiding the E=MC^2 issue.
    If you apply force to a massless object, how quickly does it accelerate? F = ma, but if m = 0, shouldn't that make it impossible to exert a force upon it, since at any acceleration, F would equal 0 as well?

    Dr Krauss,
    A friend and I were having a discussion regarding cosmology. Specifically, it was related to the (flat) shape of the Universe (as told in your "A Universe From Nothing" lecture re: the possibility of a zero total energy universe.).

    The question came up, "Well which part of the Universe is he talking about?". Is the entirety of spacetime flat? Or is it just space by itself? It has been my understanding to this point that, when discussing the universe in the cosmological sense, it complicated things to separate space from time while my friend believed (based on wording in papers) that it was merely the spatial portion of the continuum being referenced.

    Lawrence Krauss answers random emails? That's pretty fucking awesome of him.
    It is difficult to free fools from the chains they revere.

    Indeed it is. Didn't even take him that long.

    That's exactly why I like it.

    I'm actually pretty stoked to be told I was wrong in this case.

    What is this, I came in here expecting to see people still trying to explain stuff to people that would clearly never get it and instead I see Semaphore's victory dance and Laize admitting he's wrong? Did this thread enter an alternate reality?
