I'm a plasma physicist, and personally I love weird results - new mysteries to solve! That said, there are a wide range of personality types out there. And I would also be extremely surprised if the correct solution to some particular

The supermassive black hole in the giant elliptical galaxy M87 is merely ~53 million light years away, close enough that we have now imaged it: https://en.wikipedia.org/wiki/Messier_87#Supermassive_black_...

If you're worried about bad pixels or noise, it seems like there is an easy fix: point it in a direction specified by some angles theta & phi, wait long enough to accumulate light from distant faint objects (high redshift galaxies

I did provide the data in my first comment, here it is again: https://www.aoml.noaa.gov/hrd/hurdat/All_U.S._Hurricanes.htm... The analysis is easy: copy and paste the data from that link into a new text file, then

So what you are saying is that, yes there has not been an overall increase in hurricanes hitting the US over the last 175 years, but climate change has been specifically and precisely steering the hurricanes towards the orange growing regio

Yeah, exploring data is always interesting, sometimes super interesting, and it's also healthy to approach things with a mixture of open-mindedness and skepticism - a sort of zen habit you can get better at with practice. Ideas serve m

> That's not the point being made: the article clearly states that those areas did not previously get hit by storms at this level. This is the conventional wisdom, and it is completely falsified by the actual data that I linked to.

>The areas they grow the oranges never used to get hurricanes. That's not correct: we have good data going back to 1851: https://www.aoml.noaa.gov/hrd/hurdat/All_U.S._Hurricanes.htm... Search for "FL&

Plasma physicist here, I haven't tried 5.4 yet, but in general I am very impressed with the recent upgrades that started arriving in the fall of 2025: for tasks like manipulating analytic systems of equations, quickly developing new fe

If the electron starts with zero energy at infinity (e.g. a parabolic orbit, a natural default assumption), and some of the potential energy is converted into free EM radiation due to acceleration of the electron as it is falling down the p

In pure GR an infalling observer will sail past the EH and not notice anything unusual since spacetime is locally Minkowski (ignoring tidal forces, which is valid e.g. for humans falling into supermassive BHs). If the (GR+QM) firewall hypot

In a hypothetical pure GR universe what you're saying is correct, but our universe also includes QM and that makes BH physics much more subtle, e.g.: https://en.wikipedia.org/wiki/Firewall_(physics) and we can&#x2

To follow on a bit, the wikipedia article: https://en.wikipedia.org/wiki/Bremsstrahlung links to a paper by Weinberg: https://arxiv.org/abs/1903.11168 and a quick skimming shows that he's per

Hi greysphere, you are definitely correct that one primary thing preventing velocity of the electron from exceeding than the speed of light is the presence of gamma in the relativistic force law, aka \partial_t (m_e \gamma v ) = q_e(E + v \
