ohwilleke reacted to jhonconnor's post in the thread I Why is there such a difference between the total cross-section data? (simulation vs. experiment) with
Like.
Well, I found that it's due the contribution of other states. In other words, for energies below 1 MeV, ##^3\mathrm{S}_1## and... -
ohwilleke replied to the thread B Asteroid 2024 YR4 has a 1% risk of a multi-megaton impact in 2032 (now ruled out).Crude order of magnitude, back of napkin estimates are still probably good enough to rule out EMP as a serious risk of the proposal. I...

Informative.
I think EMPs radii are on the order of hundreds of miles - maybe thousands of miles - not tens of thousands of miles, let alone... -

You have to if you study mathematics or modern physics. Although your main target is QM, the general theory of relativity entails...

Yes. Only in the sense that "the vacuum structure" has the fact that spacetime is locally Minkowskian built into it, and that embodies...
