Space not as knotty as thought.

The very fabric of space is not as "knotted" as some theories predict it should be, say researchers.

Just after the Big Bang, the Universe began to coalesce into the structure we see today, which in some theories would result in knots or "textures".

The warm glow left over from that is now spread across all of space, and is used to test theories of those moments.

But a close study of this glow reported in Physical Review Letters has found no evidence of these textures.

Good bye String Theory?

String theory is has too many knobs that could be turned for it to die easily.

It tries to have the best of both worlds, falsifiability, and the ability to survive being falsified.
