Scientific Debate: Why I assert that Darwin's theory of evolution is false

[Alex K]

As far as I am aware, "multiverse" is just a hypothesis at this stage. Although I would not find it at all surprising if there were other self contained "universes" like ours, and ours started as an offshoot of another somehow. For example, you can stack any number of infinite 3-D planes in 4D space without them intersecting so they may appear distinct.

Another nice hypothesis I have heard, which is actually quite similar to one I came up with ages ago, is that our 3D space is the surface of a 4D black hole.

Trying to think in 4D space is guaranteed to drive you mad after a while. It's just... at right angles to all three... where is it?

Yeah, multiverses either of the Inflation type or of the many worlds qm type are of course speculation. They are suggested by the equations, but it's something that is hard to test... What gets me is that many worlds qm is actually simpler than having no many worlds.

I've done my phd on collider tests of the so called warped extra dimension scenarios. For many applications it is a good strategy to ignore the four usual spacetime dimensions(or better, not ignore their presence but leave them implicit) and to working only with the extra dimensions if there are just one or two. Symmetries of the problem can often be used to reduce the number of dimensions that need to be looked at explicitely. For example, without strong gravity, spacetime translation invariance, if present, can help because the laws of physics do not depend on the position inordinary space . If one is lucky, the geometry more or less factorizes such that one can for example picture the six extra dimensions of the superstring as three pairs of dimensions on paper. Whenever true higher-dimensional phenomena are analyzed which have no lower dimensional analog at all, one is basically forced to let the maths do the talking and do without a concrete mental picture of the space. Often it is nevertheless possible to have a kind of intuition about the behavior of , say, fields in 4 or more dimensions which is directly informed by the equations, without using a mental picture of the higher dimensional space itself.
