Interesting fact about Venus:
The current theory is Venus became uninhabitable very soon, but according to some models there is the possibility that Venus remained inhabitable for a lot more than previously thought, even 2 billion years.
For now it's just an hypothesis, but 2 billion years would have been more than enough to produce life and even significant evolution.

Does the event horizon of a black whole represent the maximum energy density that space-time can contain? If energy is lost via Hawking radiation the diameter of the event horizon decreases, but more mass/energy enters the event horizon increases.

Well then you should be fine, probably better off than many others in the class.
It's hard to imagine you're forgetting elementary shit if you did really well on two tests, so you may know more than you think you do.
Just do the problems at the end of each section, even if you have to use chegg or something. Don't worry about scamming yourself, shit doesn't even get real until chap 7 anyway. Do 2 hours of problems every day for 3 weeks and you're almost guaranteed an A

the data hasn't been made more available, in general it's locked in the data accessibility nightmare that is academic publishing. if it's even published at all.

the volume of satellite and telescope data made public is disorganized, unsearchable, and has to literally crowdsource initial characterization a lot of the time because there's so much of it. and then you've got plenty of data that isn't made public for years, and you have a perfect recipe for making systemic bias rampant

you're watching the real time collapse of the cultural pedestal academia used to occupy. welcome to the consequences of pretending that science had long ago excised the institutional rot that kept phlogiston alive for over a century (our new magic dark fluids are completely unrelated for reasons (the reasons are literally observations inconsistent with theory, used as if to prove the theory))

truth is, scientists are humans, and worse, they're emotionally invested humans - this is just what happens when science loses its philosophical and epistemological underpinnings in a misguided effort to better sell certificates. doubt is a healthy place for science, certainty isn't. shame certainty is so much more profitable (and i don't mean that in a greedy sense, i mean that in a "this is the only way we can get grant money" sense)

> lensing of stars occluded by the singularity's ergosphere during their orbit really should be lensed
There are currently none known to do this.
>many of those orbits should themselves be distorted by the gravitational lensing, but aren't
[citation needed]
>the observed orbits behave as though they were viewed through an uncurved spacetime following the paths that would be defined not by SR/GR but by what SR/GR adopts from Newtonian mechanics
Wrong.
https://arxiv.org/abs/1807.09409
https://arxiv.org/abs/2004.07187
>gravitational lensing in general has trouble reconciling the difference in distance and the motion as well as the masses required of the foreground object - which is annoying when you realize that "Einstein Rings" were actually discovered by Halton Arp and completely ignored by cosmologists until they found a way to relate it to general relativity
Another united claim. Arp did not discover the first ring, which was found by radio astronomers.
>>14423201
Which means twice as much dust. To the Sgr A* it's already 30 magnitudes in the visible. Even in the K band that is still 3 mag, so 6 to the other side. This is a factor of 250 in brightness. Then combined with the fact that there are so many stars in the galactic center that the smear together as a lumpy background preventing fainter sources from currently being detected. It should be possible in the future but the current expectation is to find much less than one background star lensed.
