Earlier quoted context omitted.

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.

What would a universe with equal amounts of matter and antimatter look like?

It would depend on how it's distributed. If it's very homogeneous, totally anihilated. If there are galaxies of matter and galaxies of antimatter, more or less like us with a bit more background radiation.

From a layman's point of view antimatter seems like an ideal spacecraft fuel. It's as energy dense as E = mc^2 allows, and if you have infrastructure to make it, the only input you need to produce it is electricity.

Being able to transport it seems like an important piece of that puzzle.

Production and storage would need to be scaled by many orders of magnitude, but that's merely an engineering problem...right?

Stop, driver should have license for hauling antimatter and as far as I believe no one is giving those out. That’s major offense in trucking industry.

I'm glad we have an expert on Swiss commercial trucking regulations here.

I know this is all just tongue-in-cheek, but for the record, they only drove it around for 30 min around the lab site, not on the open roads.

Very tough engineering problem. Amount transported is 92 atoms. A mole (1 gram) of anti-hydrogen is 6.23x10^23 atoms.

Yes, only anti-truckers can haul anti-matter since normal CDLs only let you transport ordinary matter. You have to be very careful not to let the anti-trucker go to a ordinary truck stop because things really go down if they run into a ordinary trucker.

There is some good greta joke hidden there but I had enough dovnvotes for today
