Am I alone in being able to spot total tripe when I read it

Not a string theory fan I take it?

String theory helps match general relativity up to quantum physics and "predicts" the properties of known particles very well and also is one of the few viable theories that gives fundamental particles non zero volume. So it has a good basis in reality and could push physics forward to greater understanding

I am not against all theories that involve more than the dimensions we can directly perceive. Just those that have obviously been made up on the spot without any attempt to check that the theory matches up with known facts.

If more dimension exist why can we not "see" them. They would be nothing inherently special about them that would make them invisible to our eyes. String theorists take the view that the higher dimensions are tightly closed in very small loops, too small to see. This is reasonable.

Book " The trouble with Physics" / by Lee Smolin /
Part 8. The first superstring revolution.
Pages 126 -127.
". . . the growing catalog of string theories meant that
we weren"t actually studying a fundamental theory." . . .
" . . . but the many versions of string theory opened up
the possibility that it was true of essentially all the
properties of the elementary particles and forces. This would
mean that properties of the elementary particles were
environmental and could change in time. If so, it would mean
that physics would be more like biology, in that the
properties of the elementary particles would depend on the
history of our universe. "

" . . . at least one big idea is missing.
How do we find that missing idea?"

Nobody knows what Minkowski 4" D really is.

If relativity is correct we live in 4D space-time. So we do know what it is. Its what we live in.

If relativity is not correct then we do not know what 4D space-time is.

How do we decide if relativity is right or wrong?
Philosopher's would try argument. They throw words around. They use every day experience. But language is limited and imprecise and everyday experience does not include travel at high speed or strong gravity.
Science's answer would be to look for evidence from experiments. This is not perfect but is more objective. Sometimes science seems not to make sense to our brains, but there is nothing to say that the universe was meant to be understandable by a human mind.

Relativity does not require more than 4 dimensions or a multi-verse.
===.
1. We live in 3D + time.
2. SRT is correct in -4D ( in negative Minkowski ) spacetime continuum.
