Deep Underground Laboratory Reveals Results of Hunt for Quantum Gravity, String Theory - The Debrief They can now check out theories of quantum gravity! Some people were worried that theories of quantum gravity could not be tested, that they were all just intangible imagination, but it looks like it was just a matter of not being able to test these models with then-current equipment, not that it was impossible to test them. So, now, they built the equipment, and they are starting to test theories of quantum gravity to see which ones are real. The news article said that it disproved String Theory. But they didn't clarify whether that was all of String Theory or just some interpretations of String Theory are now off the table, that is to say they were wrong, while other theories of String Theories (plural) are still valid, for now. But, all in all, look out Michio Kaku! They are putting your job at risk (he's a String Theorist).
