Hawking's Information Paradox solution

Our universe aways preserves information, according to Hawking's result, which means that information never leaks elsewhere.
Hawking used the example of travel to alternate universes to demonstrate what he meant. Since information never leaks out of our universe, travel to another is impossible.
However the result has nothing to do with alternate universes, they're just useful in demonstrating certain features. (At least this is my take on it)

Let's say I'm in empty space, far away from everything and I throw a ball forward at a constant speed. The ball will move in a straight line away from me. (I don't think anybody can disagree with this)
Not only is this a straight line in space but it is also a straight line in spacetime. (Why it is also a straight line in spacetime takes a while to explain, so I'll skip it for now unless you're interested.)Now let's say I'm near the Earth. The Earth warps the nearby spacetime into a new shape. I throw the ball again, this time it falls toward Earth. It has again followed a straight line in spacetime. However because the space has a different shape, straight lines usually lead to Earth. This is a shape called a monkey saddle, with straight lines in the space drawn in it. As you can see straight lines in a curved space can be very different from straight lines in a flat space.Gravity is nothing more than particles following straight lines in spacetime. This is why two objects of different masses fall at the same speed, following a straight line doesn't depend on your weight.

The warping of spacetime is caused by mass/energy density, energy/momentum flux, pressure and viscosity of a given piece of matter or a field of force(e.g. eletromagnetism).
However a better word than caused is related, for every distribution of matter and force there is a corresponding spatio-temporal shape. When you have one, you have to have the other.
Gravitational Forces are a result of the warping and the warping is required by the existence of a given distribution of matter & force.

There is distinction between a framework which attempts to describe a larger regime of phenomena by building on the implications and physical results of Quantum Field Theory (String Theory) and a set of ideas drawing vaguely from the concept of multiple dimensions (That site).For instance SU(5) Unification was an idea which turned out to be incorrect, however it respected what we already ready knew about relativistic quantum mechanical systems and was a solid extension on the gauge principle common to such systems.
Contrast this with a random idea which incorporates nothing of what went before.A strict Popperian technicality of both ideas not having been put to the test experimentally does not mean they are to be considered on equal footing.
