Holy! So, everyone on Earth is dead in Marvel? I'm out the loop.

How dense is it? It seemed pretty empty when Thor was flying around in it, or have things' changed?

The outer layer was hard to crack though I remember.

Time travel shenanigans means it never happened.

Sentry/Rogue rammed it at high speeds and didn't put a dent in it. It stands to reason that something that durable/hard/dense would weigh more than conventional matter like rock or shit comparatively sized.
Rogue at the time had the power of hundreds of heroes (Hulk, Wonder Man, Hyperion, etc), and Sentry was around as powerful apparently.

But anyway, Exitar was no less empty than a normal human is.

Seems all this shit would add up in weight.
