At first blush, this article seems to say that there’s a solid hypothesis for which the math works consistently, and they know what they want to do in order to test that hypothesis. It’s just a matter of designing and performing experiments.
But then, I read this:
[Co-author] Weller-Davies added: “A delicate interplay must exist if quantum particles such as atoms are able to bend classical spacetime. There must be a fundamental trade-off between the wave nature of atoms, and how large the random fluctuations in spacetime need to be.”
I know atoms aren’t “particles,” and I’m pretty damned sure they’re also not quanta.
Atoms are composite particles. And they surely are quantum particles as you need quantum mechanics to describe their behavior
So, we’re just calling anything a “theory” nowadays? How about the scientific method? Or is that just too much work for anybody in a post-Einstein world?
