    the Schrodinger's cat experiment helps give me one of my favorite sayings.

    "You may think the glass is half empty, he may think it's have full, but I KNOW that just by measuring it, you've changed the outcome."

    A bit off topic now, but in relation to warp-drive and traveling faster than the speed of light, it technically impossible but, crazy theory time B)

    This would only work with drones unfortunately and not humans. But if we were to find parallel universes to exist and find a way to travel through them, we could assume that this universe has a completely different time frame, so hopefully, what you could do is send a drone into the parallel universe, let it travel how many light years over millennia. and then when it reaches its destination bring it back to our universe, seeing as this universe has a different time plane, hopefully it would seem that it would have travelled to that area in an instant in our universe, as if it warped when actually its just taken the journey in that universe.

    So maybe, it would be possible that way, or not. What the heck, but hopefully as we study the universe and find ways to defy physics we can forget about the difficulties.

    On topic now, isn't Schrödinger's cat the theory of quantum entanglement?

    Kinda, quantum entanglement occurs when two or more particles share the same state. When the one changes spin/direction/etc the entangled particles match it. Where schrodinger's cat enters into this is the idea that an object can exist in every possible state until it is observed, thus collapsing the wave function. The link between the thought experiment and quantum entanglement is the superposition of states existing (multiple particles sharing the same state because those particles contain a superposition of all states)

    The idea that particles 'exist in every state' until they are observed is not strictly correct. Instead we know from Heisenberg's principle that somehow, particles everywhere are able to communicate so that no two particles ever fall into the same state.

    The act of observation is merely the act of radiation interfering with the quantum state.


    Wikipedia lies.

    You can't travel to parallel universes, that would mean you need to cross the void and that's only possible on accident with a police telephone box, or a void sphere. /Doctor Who.

    Ok, so we said that this was for serious physics. if you want a sci-fi physics thread, create one.

    ANY POST OFF TOPIC IN THIS WAY OR ANY OTHER WILL BE INFRACTED!

    Nice to hear.

    So we've already heard of Graviton detection, which was the first idea that came to me when hearing that the Higgs could be spin 0.

    What about gravitational waves? Arguably a discovery far away in future, but it could offer untold observation on the universe. Inflationary theory predicts gravitational waves the size of the universe, and we are constantly being bombarded with waves from the CMB. Never mind mapping the effects of black holes, dark matter etc.

    I was replying to a previous post voicing my ideas on how warp drives would have to work, I mentioned that it was off topic before the paragraph. and then went back on-topic to quantum entanglement. I really don't see the problem, stop being a spoil sport and loosen up man :)

    Also, I understand that this discovery of the higgs is a huge relief for the standard model. But honestly we shouldn't be so surprised if the model has faults and in the end is false. The foundations for the model were made when technology was almost mute. Instead of finding excuses to help the model we should be purposely trying to prove it wrong, if were to advance. Do you guys agree? Or should my post just me 'infracted' :p

    Well, most of the model is actually based on Feynman's work on path integrals. He conceptualised the 3D space that CERN uses to map it's particle collisions.

    I would agree that disproving a principle theory would invoke a lot of new ideas and motivation, however i'm not so sure that government funders who care more about technological development want to see you spending billions of euros, just to put the middle-finger to Peter Higgs.
