From Hacker News Original Article Hacker News Discussion

The commentary discusses theoretical limits on black hole mass and the fascinating possibility of observing ancient light through gravitational lensing.

Why it matters: Understanding black hole mass limits helps clarify galaxy formation and cosmic evolution.

The big picture: Gravitational lensing may let us observe light from our sun and Earth billions of years ago.

Stunning stat: A supermassive black hole 9000 times the mass of Sagittarius A* could have a density similar to Mars' near-vacuum atmosphere.

Commenters say: Users are intrigued by black hole size and density, and excited by the potential to observe early cosmic events through lensing.
