Does our 3-D world hold six other dimensions?

Imagine little flat people living on the surface of a piece of paper. Just the surface: their world is not even as thick as the paper, with no vertical dimension at all. Stick a pencil through the paper and all they would see is a circle, a two-dimensional cross section. Fold the paper or roll it up, and they wouldn’t know the difference.

Now you’re ready for brane-world theory, which proposes that our three-dimensional universe lies inside higher spatial dimensions, and we are no more aware of them than those flat people are of our third dimension. Since a membrane separating two spaces is a handy example of a two-dimensional object in three-dimensional space, theorists started referring to a plane as a 2-brane. By analogy, we live in a 3-brane. (Although we have four dimensions if you count time, as physicists do.)

Wow that’s a bit of a mind bender for the first read of a morning.
Enjoyable none the less. Thanks Heidi. :slight_smile:

Very interesting! Good plugs for LHC and Einstein too :thumbsup:


Yes. Such are wormholes theorised to exist, whos throats trespass accross the higher dimensions. Without stuff like this there would be no stargate sg-1.

And that my friends would be a tragedy.

Thankyou Heidi… my head REALLY hurts now :wink:

top bit of reportage tho, for that i do thank you :smiley:
