Wolfram Alpha says its approximately the kinetic energy of a mosquito in flight

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.

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

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.

Wolfram Alpha says it's approximately _one-sixth_ the kinetic energy of a mosquito in flight

When we're talking scales like 10^-23, "one" and "one sixth" are comparable enough to warrant an "approximately".

I'm not sure! One is just barely within human scale and one isn't. I think I could feel the impact of a mosquito on a sufficiently sensitive patch of skin. I'm not sure I could do the same with one sixth of a mosquito. Its like the difference between something I can lift (100 lb) and something I definitely cannot lift (600lb)

		It's also the difference between 1lb and 6lbs also, so the analogy isn't perfect. The problem is that once you approach the limits of the average human ability, multipliers can transform something possible into something impossible. I'm pretty sure I could feel one sixth of a mosquito hit me, because I've been pelted by much smaller gnats before! (It does depend on where, of course.)
