1. 'Scientists' are not monolithically and fungibly knowledgeable across all fields.
2. 'Scientists' are loathe to pronounce certainty in value-laden terminology like catastrophic.
3. The response to purported scientific consensus about the future of climate isn't so much about whether or not we wish it to be true as it is the complex analysis of the best response to the pronouncement for the bulk of humanity.

Unfortunately, it's just known as Messier 87. A galaxy as opposed to a nebula. Technically a supergiant elliptical galaxy in the constellation Virgo.

Why this black hole image is important to confirmation of the theory of relativity:

The black hole in that image:

1. is large in diameter than our entire solar system, and

2. weighs more than our entire galaxy

Soo.... Are black holes flat like the Earth and moon?

This is really cool and I love that it has made this thread so active. Even if Tyson had to try to politized the moment. :shake:

The size comparison blows my mind....

Holy ****ing hell.

Great. Now I have to clean brains up off my walls.

No way to objectively know, but it's hypothesized that they could be a zero-dimensional point.

At the least they are hyper-compressed but retain 3D sphericality. Like if the entire mass of the earth was the size of a golf ball. Would probably be perfectly round and smooth as the compressive forces wouldn't allow any other shape or any features to the region.

Likely time doesn't 'exist' as a dimension within either.

they fit on a T-Shirt.

Katie Bouman rocks!

That damn think is going to suck up our solar system someday. :eek:

holy cow. 55 million light years away. I think I am safe.
Unless AOC says different.
