On String Theory and Loop Quantum Gravity

[edit]

The provisions that allow us to clarify the testability and/or falsifiability of string theory and loop quantum gravity have not been formulated. Therefore, these theories are ORISS. Surdin called these theories fakes in one of his TV shows. I agree with him. I consider all these fabrications to be the stupidest page in the history of physics. Another caloric. And how many grants have been wasted. One question - if the length of a string is on the order of the Planck length, then what is the thickness of the string - less than the Planck length or zero? String physicists are afraid to even think about it. But philosophers persistently ask questions. You invented strings, answer them. From the point of view of quantum gravity, there can be no length less than the Planck length. Then collapse occurs. And this is inevitable. And they have been rushing around with this nonsense - hypothetical strings, branes - for more than half a century. Come to your senses. Loop gravity has gone even further - they came up with some kind of loops-cells, discrete gravity. Another invention, not supported by anything. I read, study physics. Where is it heading? I can't think about it calmly. 178.120.7.209 (talk) 17:22, 12 April 2025 (UTC)[reply]
