PRIDE CHEKERAintra- or inter connections of universes.
For now, these predictions are hypothetical, as our energy levels
are not enough for us to empirically test string theory and its
predictions since it is high energy physics.
That's why string theory had been a controversial theory since
there is no empirical tests done to prove it, its higher dimensions
or multiverses or parallel universes. In future when we advance
enough will be able to test this theory and validating it as the
best candidate of quantum gravity theory, a theory of
everything.
