Not an astronomer but if I read the article correctly the observations gathered about galaxies rotating and colliding would be explained instead by regional changes in what were previously assumed universal constants, which would be very interesting if true but 1 paper isn’t consensus yet

whotookkarl, do games w What are some good games with *zero* replayability?

90s style adventure games like Sam and Max hit the road, day of the tentacle, monkey Island, Indiana Jones, etc. Lots of comedy you can’t hear again for the first time, and puzzles that can be memorable.

scummVM can be used to run those games and runs on basically everything, phones, tablets, desktop.

So that’s also studies by astrobiologists looking at atmospheric methane because we know it can be created in large quantities by metabolism in an organism in addition to non organic processes, and in the atmosphere it reacts to sunlight so it needs to be replaced to stay present in large quantities.

This is something different where they’re looking for chemical signatures, primarily methane, indicating geothermal vents which we’ve seen providing the energy to sustain life on earth at the bottom of the ocean. If abiogenesis requires some non organic processes like sublimation, evaporation, heating up and cooling down, etc to allow a self repeating process to start and continue to hold form until it’s able to use sugars to continue to maintain itself instead of depending on its environment to kick start the life process then you’ll want to look for those phase changes or boundaries like water/atmosphere or extreme heat/cold to provide the gradient that natural process may need like those studied in systems chemistry.

That’s the zone for liquid water at the planet surface. There’s other sources of heat; gravitational pressure, geothermal vents from plate tectonics, etc. In this case they’re looking for methane with a chemical signature that indicates it comes from geothermal activity as opposed to other processes that generate methane.
