petrushka.googol Posted October 25, 2013 Share Posted October 25, 2013 (edited) Hypothetically a particle that enters worm hole enters another universe. What if this universe is an anti universe? (with anti-gravity). Gravity is an attractive force but when the particle enters the boundary of the new universe anti gravity (which is repulsive) will cause the particle to exhibit simple harmonic motion in the worm hole rather than entering the new universe. Is this conceptually possible. Empirically it seems so. Edited October 25, 2013 by petrushka.googol Link to comment Share on other sites More sharing options...
imatfaal Posted October 25, 2013 Share Posted October 25, 2013 Hypothetically a particle that enters worm hole enters another universe.Once you have started with "hypothetically" then to a fair extent all bets are off; you cannot make a trail of logical conclusions using physical laws if you start with a complete lack of certainty in your premises What if this universe is an anti universe? (with anti-gravity).This is the point - it could be an "anything" we have no way of knowing and thus almost all logically valid arguments are equally sound Gravity is an attractive force but when the particle enters the boundary of the new universe anti gravity (which is repulsive) will cause the particle to exhibit simple harmonic motion in the worm hole rather than entering the new universe.If ifs and ands were pots and pans ... Is this conceptually possible. Empirically it seems so.EMPIRICALLY - no! We don't even have any good evidence the exotic matter required (in some sensible papers) to create a wormhole exists, let alone that the wormholes are possible, let alone that anything can pass through, let alone.... Conceptually - you need a lot of imagination and precious little else and the payback for this line of thinking will probably be equally insubstantial.

BusaDave9 Posted October 25, 2013 Share Posted October 25, 2013 as matter passes the event horizon of a black hole it exceeds the speed of light. Its dimensions of space and time are destroyed. If it obtains new dimensions of space and time John Wheeler first theorized that this black hole would be a worm hole to another place in our universe. If the matter obtained new, different dimensions the worm hole would go to another universe. If such a universe had anti-gravity stars and planets would never exist. It would be an ever expanding universe with sparse atoms that would never coalesce into planets or other bodies. Link to comment Share on other sites More sharing options...
imatfaal Posted October 25, 2013 Share Posted October 25, 2013 as matter passes the event horizon of a black hole it exceeds the speed of light.says who? there is no reason that the passing of the event horizon demands this - in fact if the object were (in some bonkers way) be able to be superluminal then it may have escape velocity and the hole would not be black. Its dimensions of space and time are destroyed.maybe flipped around - but we really do not and cannot know what happens behind the event horizon. If it obtains new dimensions of space and time John Wheeler first theorized that this black hole would be a worm hole to another place in our universe.It was Weyl in the 20s soon after GR - Wheeler just named it. If the matter obtained new, different dimensions the worm hole would go to another universe. If such a universe had anti-gravity stars and planets would never exist. It would be an ever expanding universe with sparse atoms that would never coalesce into planets or other bodies. Link to comment Share on other sites More sharing options...
