Reply to Aggregate measure of financial misreporting for nearly 2,000 companies in the U.S. suggests that the collective probability of fraud across major companies is the highest in over 40 years by marketrent
It's almost like both political parties are in collusion to only help companies and the rich. The US government believes that corporations are people, and people are entitled parasites.

As someone with MS I am really hopeful and interested to see where this research goes.

Dads can too but this post isn't about dads.

Its okay, both the kids and the moms can be the problem. Don't need to make excuses for either party.

Reply to comment by zoinkability in Ultramassive black hole over 30 billion times mass of our sun has been spotted. The discovery had been made possible thanks to a phenomenon known as gravitational lensing — the first time a black hole has been spotted in such a way. by Wagamaga
Helpful. Appreciate the clarification.

For reference, Sagittarius A*, the supermassive black hole at the center of the Milky Way is 4.3 million times the mass of the sun.

At 30 billion times the mass of the sun this thing is….. big
Ultra massive black holes like this present a problem for science. Accretion disks can only become so hot, dense, and energetic around black holes before they radiate so much energy that they keep themselves from falling into a black hole above a certain rate. There is effectively a limit to how fast black holes can grow.
These super/ultra massive black holes are bigger than it should be possible for them to be, even if they experienced max growth rate constantly from the birth of the universe.
So how did they get that big?
A cool theory is that when the universe was young, dense, and hot, enormous stars formed that were so massive their cores compressed into black holes. And because these black holes are surrounded by a star which is constantly crushing matter into it, the black holes basically get force fed. The accretion disk energy is overwhelmed by the crushing pressure from the gigantic Star.
It’s a fun theory.

There is a direct relationship between the mass of a black hole and the size of its event horizon. if you know the one, you know the other. So if a black hole is the highest mass ever seen, it would also be the largest in terms of its event horizon.
That said, inside the event horizon we simply can't know what goes on. So the "actual size" (meaning, how much space the matter inside the black hole occupies) is, I believe, simply unknown.

It's mass directly as effects it's size, remember, it's not the physical object that's big, but rather the schwarchchild radius, where light can no longer escape.

I'd guess this is easily overcome in humans with social media.

There is a level of learned helplessness when you grow up around people assuming the worst of your intentions.

So it says “mass” of the sun but then they mention “something that large” implying size. I’m a dummy but those are two different things right. It could be the size of a baseball and be 30 billion times the mass of the sun. No?

Yea, I like can't even imagine the size of the sun to begin with...
