Don’t listen to them. They are hiding the truth that the Arachnids have launched a “Bug Meteor” using Bug Plasma from the Klendathu system towards Earth.

One-two punch?

Apophis then Bern-Bern...
Pow! Zap!

Communism may be defeated after all...

It’s funny. Oort is the sound it made, too. 😬

Every single time a comet makes a revolution around the sun, they lose material.

That depends entirely on how close they get to the sun. If they never get closer than, say, the orbit of Neptune, they lose basically nothing -- it's just too cold. "Dirty snowballs" aren't going to evaporate at -200 or -300 Fahrenheit. Keep in mind also that those orbits take hundreds or thousands of earth years to complete. That means:

The comets we normally see cannot have lasted more than a 100,000 years

that that's not necessarily true at all.
