This thread has drifted pretty far but I will throw something in regarding gravity and particle interaction:
The Laser Interferometer Gravitational-Wave Observatory (LIGO). A partnership between Caltech, MIT, and the National Science Foundation, LIGO’s job is to detect small fluctuations in gravitational waves that are caused by stellar black holes colliding millions and billions of light years away.
Until recently, the idea that gravity waves even existed, let alone compress and stretch space-time like a Slinky was only theoretical. Why are gravitational waves important? Because they prove that the very space and time we live in is, in fact, flexible, and sometimes very flexible (interstellar travel?).
The U.S. government has been teleporting objects such as electrons for over a decade. Yes, teleportation is real. Recently,the Micius satellite confirmed successful teleportation of a quantum object from Earth to orbit. See below.
