Dimensions, Gravity, And "white" holes...

If there are any white holes or devices to travel though space the goverment probally knows about it

How would we detect white holes?

Probably by seeing super fast matter coming out of them, which is similaar to how we detect black holes, except these white holes wouldnt be sucking in anything near them, and i havnt heard about any discovery like that before.

Btw if anything CAN happen it WILL happen, what this means is that everything has a probability of happening, but nothing has actually happened until it is actually OBSERVED, which then collapses the wave function and we see ONE thing happening of the possibilities, but at the same time the universe splits and in the other universe the other thing happens?

For example, say a atom emits 2 umm electrons with opposite spins, each electron has a 50/50 chance of having a certain spin, call them up and down. Once u measure one of them and lets say its up then the other one instantly becomes down spin, but then since if something can happen it will happen, does a universe split from ours have the first photon we measured be spin down then, and the other spin up?

Have i got it right?

There is a universe where both are up, one is up and the other is down, one is down and the other is up, both are down, and where only one exists, and where 3 exist, and where they both undergo decay, and where one undergoes decay, and where they aren't observed, and where a giant foot comes down and somehow squashes them - a universe for everything. _But,_ the probabilities point to there being the largest number of universes where one is up, one is down, both are up, or both are down. Looks like we won't see 'atom-stompin' feet for quite some time.

'White Hole' theory is an established idea, in fact, much like multiple universe theory, John Titor made mention of it too! It's exactly what you've said it is, and it is the concept of the inverse of a black hole. The Big Bang is theorised to possibly have been a White Hole, though it stopped emitting energy, leaving us to wonder whether it can really be thought of the same as a black hole, considering that black holes last so darn long.

Just search google for "White Hole" and try to throw in a physics reference or turn on a search filter I had some bad results with a grade 4 project on 'Black Holes' searched up at the local library.

The Universe is the 3D surface of a 4D sphere, and gravity is merely the conformation of geometry as stated by Einstein. Most gravity we see is associated with mass, but that is not exactly necessary. If the Sun were suddenly gone from the Universe the gravity wave would not reach us for 8.33 minutes. I would propose a theory that most gravity associated with mass would all have the funnels stretched in one direction on the 4D sphere surface. Just for now say pointing inward to the center of the 4D sphere. A white hole might be a gravity conformation that pointed in the outward from the center of the 4D sphere, perhaps without mass?

Do you think it would be possible to have gravitationless mass? Or could mass itself simply be stationary/'fixed position' gravity? Or could you have a gravitational conformation with out mass?

Also I think if our Universe is a wave expanding out from a point in the center of a 4D sphere, that same point might be generating many waves/universes. Each being essentially defined as a valley or local mininmum (calculus funtion stuff) that defines a Universe. To track back or forward to another Universe, Im guessing it would be best to rise over the ridge to the next valley/universe. (you could go off the Universe generation wave pattern, but I would guess that to be riskier. If this were true it might give a certain convergence quality to each Universe/wave.

Addtionally if you think of a gravitational mass body as having some axis that is sort of perpindicular to the 3D surface of the 4D sphere, it would fit with string theories idea that gravity is a weak force because it doesn't all track or stay parallel with the Universe. Gravity kindof strays off the universe while most Electro magnetic radiation stays with the Universe (is moving parallel inside the 3D surface of the 4D sphere).

Another disassociated thought, perhaps the Universe has a sort of convergence via Quantum, because all the unobserved events are ambiguous and therefore don't splinter into other possibilities. Until you view it it is indeterminate. Which is wierd because it implies that perhaps only the observations of the Universe cause splitting of the Universe possibilites. But it doesn't worry me too much, because I figure spits that converge seem likely to happen about as often as splitting/divergence happens.

Is it possible for someone to be able to feel or "sense" gravitational pull?

Apart for the normal method, you can use the seperation between two test particles to measure the geodesic deviation and you can determine the geometry of spacetime from that.

Geodesics are straight lines through curved spacetime, free falling worldlines. Floating in space and falling are geodesics, standing on the earth isn't. The difference between the lines on which test particles travel allow you to determine how space is curved and that allows you to calculate the gravitational pull (that is, the Newtonian approximation of gravitational pull).
