Which seems suprisingly high given that it's 92 protons worth of antimatter!

Definitely, I've had a mosquito hit me while flying and you can actually feel it hit your skin.

The subject of this story is a single proton that you would definitely feel if it hit you: https://www.fourmilab.ch/documents/OhMyGodParticle/

I don't think that is the case. The kinetic energy of these super-energetic particles is often compared to a tennis ball. But that energy isn't released at once, so even if it would interact with yourself, that interaction creates a particle shower that takes most of the energy with it. I don't think we can feel one of our atoms getting violently ripped apart.

There’s Anatoli Bugorski [1] who accidentally put his head into the path of a high energy proton beam.

The injury resembled nothing like being hit by tennis balls.

> He reportedly saw a flash "brighter than a thousand suns" but did not feel any pain.

He’s still alive today, age 83.

Which kind of mosquito? European or Asian?

E=mc^2 and c^2 is a big number.

Famous tweet about conversations with God.

Except the fine structure constant

indeed, but note that c^2 is just a factor to convert between units here and is completely arbitrary (or rather, c is so high because our units are human scale)

indeed, in the most natural systems of units in this area, we set c = 1 as to simplify the equations

8 minutes to do a mere 1AU. Pretty slow.

(not /s for clarification)

499.004783836 seconds. So, more like 8.32. I initially looked it up because I misremembered AU being a diameter rather than a radius.
