The Spin Flip Transition

The spin flip transition, which you can all learn more about on starts with the bang podcast number 41 with Beth Fernandez that we did just last month. So if this hydrogen atom is falling into an ordinary stellar black hole, then that 21 centimeter radio signal would get stretched out. And eventually, the math would tell you that it's going to have a wavelength that's longer than the size of the event horizon of the black hole itself. I feel like there might be some other very subtle effects that happen if you if you actually tried to to calculate what the radio signal would be from this single hydrogen atoms. But this is such a detailed calculation that I think that it's probably too technical for
