The aurora borealis would be amazing, for a limited time.

Certainly better than the one in my kitchen.

There wouldn't be an Earth for very long.

Thanks for this clever summary! Now there's no point in clicking the video /s

We would be long gone. Can you imagine what a football-sized (or even bigger) antimatter meteorite would do?

Hint: six to seven grams of antimatter is the equivalent of the bomb that took out Hiroshima.

6 to 7 grams? No. 1/4 of a gram of antimatter reacting with 1/4 gram of matter is just about the right mix. That’ll be around 15 kilotons.

The video doesn't mention the sun. Could an antimatter sun shine?

[–] rockerface@lemmy.cafe 10 points 7 hours ago

In fact, yes. Photons don't have a charge, so anti-photons would illuminate the Earth all the same. The issue, as the video points out, will come from too much energy hitting the Earth's surface, not too little.

EVIL antimatter sun that STEALS your light and heat
