Given a couple million years of evolution most of the planet should be fine after the anthropocene mass extinction event. We just won't be around to appreciate it.

I dunno about that. Humans kinda worse than cockroaches in some respects.
(PSN: Morninglord) (Steam: Morninglord) (WiiU: Morninglord22) I like to record and toss up a lot of random gaming videos here.
Fish fact you probably already knew: Blobfish actually look like quite normal fish at the crushingly high pressure depths they live in, they only turn into blobs when they are brought up to the surface and their bodies are horribly mangled by decompression.
Diving bell accident
On Saturday, 5 November 1983, at 4:00 a.m., while drilling in the Frigg gas field in the Norwegian sector of the North Sea, four divers were in a diving chamber system on the rig's deck that was connected by a trunk (a short passage) to a diving bell. The divers were Edwin Arthur Coward (British, 35 years old), Roy P. Lucas (British, 38), Bjørn Giæver Bergersen (Norwegian, 29) and Truls Hellevik (Norwegian, 34). They were assisted by two dive tenders, William Crammond and Martin Saunders.
Hellevik was about to close the door between the chamber system and the trunk when the chamber explosively decompressed from a pressure of nine atmospheres to one atmosphere. One of the tenders, 32-year-old William Crammond of Great Britain, and all four of the divers were killed instantly; the other tender, Saunders, was severely injured.
The decompression chamber as seen from above at the moment the accident occurred. D1–D4 are divers; T1 and T2 are dive tenders. The trunk is the section that joins chamber 1 to the diving bell.
Just prior to the event, decompression chambers 1 and 2 (along with a third chamber which was not in use at the time) were connected via a trunk to a diving bell. The connection made by the trunk was kept sealed by a clamp operated by Crammond and Saunders, who were experienced divers. Coward and Lucas were resting in chamber 2 at a pressure of 9 atm. The diving bell with Bergersen and Hellevik had just been winched up after a dive and joined to the trunk. Leaving their wet equipment in the trunk, the two divers climbed through the trunk into chamber 1.
The normal procedure would have been:
Close the diving bell door, which would have been open to the trunk.
Slightly increase the pressure in the diving bell to seal the bell door tightly.
Close the chamber 1 door, which was also open to the trunk.
Slowly depressurize the trunk until it reached a pressure of 1 atm.
Open the clamp to separate the diving bell from the chamber system.
The first two steps had been completed when, for an unknown reason, Crammond opened the clamp that was keeping the trunk sealed before Diver 4 (Hellevik) could close the door to the chamber. This resulted in the explosive decompression of the unsealed chamber system. Air rushed out of the chamber system with tremendous force, jamming the interior trunk door and pushing the bell away, striking the two tenders. All four divers were killed; of the tenders Crammond was killed while Saunders was severely injured.
Medical findings Warning, explicit description
Medical investigations were carried out on the remains of the four divers and of one of the tenders. The most notable finding was the presence of large amounts of fat in large arteries and veins and in the cardiac chambers, as well as intravascular fat in organs, especially the liver. This fat was unlikely to be embolic, but must have precipitated from the blood in situ. The autopsy suggested that rapid bubble formation in the blood denatured the lipoprotein complexes, rendering the lipids insoluble. The blood of the three divers left intact inside the chambers likely boiled instantly, stopping their circulation. The fourth diver was dismembered and mutilated by the blast forcing him out through the partially blocked doorway and would have died instantly.
Coward, Lucas, and Bergersen were exposed to the effects of explosive decompression and died in the positions indicated by the diagram. Investigation by forensic pathologists determined that Hellevik, being exposed to the highest pressure gradient and in the process of moving to secure the inner door, was forced through the crescent-shaped opening measuring 60 centimetres (24 in) long created by the jammed interior trunk door. With the escaping air and pressure, it included bisection of his thoracoabdominal cavity, which resulted in fragmentation of his body, followed by expulsion of all of the internal organs of his chest and abdomen, except the trachea and a section of small intestine, and of the thoracic spine. These were projected some distance, one section being found 10 metres (30 ft) vertically above the exterior pressure door.
It's...extremely impressive that we are capable of surviving at 8 atmospheres tho.
As horrible as that accident is.
In some ways the deepest parts of the ocean are more difficult to deal with than space.
The Core was a pretty bad movie but it was actually scientifically interesting until they hit the point where a character all but looks at the audience and says "Now forget all that we're going to do a dumb silly pulpy adventure story."
One of the things a character says prior to that point is responding to a "If we can put a man on the Moon" comment with "Space is easy! It's empty! We're talking about millions of pounds of pressure per square inch!" (Of course this is not taking into account Earth orbit, with the space junk, but...)

humans who are trained can deal with roughly 7-9 atmospheres
anything past that though? fuck off
also, the bigger issue is creating vessels that won't crumple like dixie cups if a slight woopsie poopsie happens to the structure

I'm sure other people already know this (does seem to be old news) but I just learned that platypuses don't have stomachs. Not only that, but they ditched all the DNA that codes for making stomachs, so even if there was some kind of pressure to get a stomach again, they couldn't.
It just occurred to me the other day, like, birds are dinosaurs, but we never think of dinosaurs as birds.
What if raptors liked sliding down snowy slopes, or T-rexes were just giant cockatiels and would love to sing and dance if music existed back then.

It's very likely some of the more bird-like dinosaurs had mating displays like modern birds!
it's hard to be all "yeah American exceptionalism, we have slipped the surly bonds of Earth and went to Mars!" if you have to add "well and so have a bunch of other countries."
Yeah I conspicuously only hear about other countries' space programs when something goes badly for them! Wonder why :rotate:

While putting this at the feet of western media is tempting, a lot of lack of coverage of the Chinese lander is as a result of China self-censoring. While it's been known they had sent a lander and it was going to Mars, Chinese State media didn't do a big live feed, or even announce when the landing would be because ~secrets~ and not wanting to lose face in case of failure. We only had a rough guess when it would be because of orbital tracking, ran a couple news stories about it probably happening, and then China announced it was successful without very much in the way of pictures or video, so all that could be said is 'that happened'.
Anyway, all the usual astro science social media feeds and blogs were aware and mentioning this, but the complete lack of open and free information from China about their lander has pretty stifled any media coverage anywhere about what they've achieved. What you see there constitutes more real information from China than has been released to date from the time of launch to now, so, you know, I'm much more comfortable saying the lack of knowledge about this is as much on Chinese Authoritarian media control as it is any patriotic slant to western coverage.

I was mostly talking about like, the ESA has an orbiter around Mars. Russia, I think India has one? the United Arab Emirates sent some stuff to Mars
not hearing a lot about China's efforts is definitely them playing it close to the chest. vest? one of those.
edit: also I think the Soviet Union sent some orbiters back in the 70s
