I think our understanding of the universe is missing a few fundamental things. This is why we can't bridge Relativity and Quantum Mechanics.
If you can't test something, it's not science, it's philosophy, or worse. There might well be some useful concepts in string theory, but it doesn't seem to describe the actual universe we live in. As such, it's not useful except as a form of masturbation for math geeks.
IMO, the Electric Universe has much more going for it than string theory ever has. It has at least made predictions that have been tested.
If you can’t test something, it’s not science, it’s philosophy, or worse.
For example logic, part of philosophy, is a rare commodity these days.
We have too many experiments that logic says won’t work but we have to go through the experiments anyway these days. Einstein did many thought experiments before he came up with his final ideas. Not done today because the wilder you idea is these days, the more attention you get, whether science, economics; religion or politics.
We have people that still believe in spontaneous generation. We laugh at the idea of spontaneous generation but seriously support the current idea which adds time and randomness.
