If deep sea divers need to come back to the surface slowly so their bodies can reacclimate to standard pressure, do astronauts undergo a similar reacclimation process as it pertains to gravity?

Divers need to decrease pressure slowly because it causes dissolved gases in the blood to become gaseous again, which can block blood vessels. I don’t see a mechanism for something similar with gravity. Otherwise fighter pilots would be dead with every flight. The only thing close is muscle loss, all other detrimental effects of zero g don’t really care if gravity returns fast or slow, I think.

My rough understanding is that it's a very strange environment for the body to be in for an extended period of time, and when you come back, gravity hits you very, very hard.

It seems like they all absolutely would need to have detailed tests when they come back. Whether there was another illness or emergency who knows. But the shock of sudden gravity could trigger things.

I think this type of headline just gets views because people want to believe they made alien contact or something ridiculous.

Think they have the sqwits?

Think the may have the sqwits?

tight-lipped, thats a definitive symptom of bieng probed by the aliens, ovipositors. Main reason for the space force getting orbital is just this. With the aliens getting frisky,man oh man, what a mess you got 0G, 1G, 2 G,3g,up to 5G and they are talking 6 of em, beaming the virus strait from 8 chan into your pre frontal cortex.
