ok wait I thought we just learned from mike rowe theres no proof of black holes. is this some ground breaking new clue or what?

no that’s why we think there are black holes in the first place.

idk if you’re half serious but dark matter/energy isn’t dense enough to create this type of gravitational pull.

Yeah! It's incredibly fascinating; black holes haven't been proven, they're just one explanation for some crazy space physics.

Regardless, there's still incredible debate about it in the scientific community.

there is debate on specific details. not whether or not they exist.

Shit, you're right; I just went back to a few papers. Thanks for the correction.

But Mike Rowe said they weren't real tho

So, point here is that it is a bit odd to have Rowe host. Post on fp defended a position making it seem like it's a huge question still/

But it sounds to close to deniers who give large weight to a small amount of sceptics, similar to my dealings with Evo deniers, etc./

The evidence is so strong for singularities that the null is now what phenomenon would cause stars to behave this way if not for black holes

He's opinionated. Fine by me, he's not forcing me to agree with him. I agree about the skepticism; always start by being skeptical.

because they are very much real... not just some mathematical “theoretical” construct. does this really need to be defended?

8 years ago | Likes 10 Dislikes 11

They are the most probable explanations, but there are alternatives e.g. gravastar. So while they are probably real, still theoretical.

8 years ago | Likes 3 Dislikes 2

Absolutely because a theory is always up for change or revision. There might be a black hole, or it might be something else we weren't aware

Mike Rowe doesn't have the qualifications to make such a claim credible.

I'm pretty sure he was narrating aka reading a script. Not making the claims himself.

The evidence that supports the existence of black holes are only theories that attempt to explain why occurrences like this take place.

That black holes are what we think they are. All we know about them for suris there is some sort of extreme gravity anomaly within galaxies.

The mass can be fairly precisely calculated just from that one orbit around it.

8 years ago | Likes 1 Dislikes 0

... if you know the mass and plain of orbit of the star orbiting. Not sure we know this parameters.

8 years ago | Likes 1 Dislikes 0

The mass can be calculated from it's orbit using Kepler's Laws. That compact star, i think, is Sagittarius A*, so the ref star is S2... /1

8 years ago | Likes 1 Dislikes 0

Now check wiki to confirm results... ~4 million solar masses, so within the error range. That's the short of it. /4

8 years ago | Likes 1 Dislikes 0

(a=year), and now we apply Keppler's 3rd law to calculate the total mass of SgrA* and S2, which is 3,3*10^6 (+-1,0*10^6) solar masses. /3

8 years ago | Likes 1 Dislikes 0

Which has semi-major axis of ~5,4 (+-0,4) light days. From that you calculate the period (P), by dA=(dt/P)*A_ell, making P=15,7 (+-0,7) a /2
