Newer studies on planets with tidal locking suggest that heat would actually transfer across the planet evenly if it were to have an atmosphere and an ocean. So I’d argue that complex multicellular photosynthetic life would evolve in the daylit side and be the most successful there. The terminator would be at an eternal dusk and wouldn’t produce as much luminosity and thus energy, imo. (This is hearsay from the youtube channel KYPLANET so please correct me if I’m wrong.)

This greatly depends on if we are talking about a deep vent life start vs warm pond / shallow vent life start probably

huh that’s cool. I tend to assume the ocean would work but i certainly wouldn’t want to go to the surface of an ocean with enough sunlight to form hypercanes,

Also wouldn’t hypercane presence be negative to most surface life of a planet?

i mean. sure. but so are hurricanes and tornadoes and dust storms and earthquakes and volcanos when they aren’t fertilizing the ocean and lightning and such, clearly life can manage, i just wouldn’t want to manage.

Pretty sure hypercanes actively harm/destroy the ozone layer though, since they reach high enough to disturb it

We actually have an ocean planet with an atmosphere that is likely tidally locked, it’s called LHS 1140 b and it’s my favourite exoplanet.
LHS 1140 b - Wikipedia
There’s a couple scenarios for its average temperature, if its greenhouse effect is much stronger than earth as it likely is due to its increased mass, the avg temperature is 23 degrees Celsius.
Although if its similar to earth then its likely only -7 degrees Celsius.
So we either have a cold ocean world, tropical ocean world or a freezing eyeball planet.
It’s probably the most likely planet we have found so far to be habitable as we know for a fact it has an atmosphere and large amounts of water.

And considering the star’s age it could host some impressive life… If it can develop it in the first place.

If it isn’t capable of developing life on its own then I’d imagine it’d be a pretty good place to test out colonization on for some advanced species.
You could just go there and build on it without the ethical concerns.

Well you would first need to find out how to stabilize things in such a world without a stable surface

i mean. we could make a big boat ??? or an oil platform or large raft or submarine for exploring.

itd be very hard to prove there’s no life. we still go to great lengths to avoid letting bacteria on the mars rovers, and mars is a dead world

The reason there might be a good chance that there’s no life on LHS 1140 b is because the oceans might be so deep that the bottom freezes over due to pressure and doesn’t allow hydrothermal vents.
If this is true then there won’t be anything living on it even if its perfectly fine for life. (No abiogenesis)
Well, unless panspermia is a thing then there’d be stuff on it.

we don’t know what it would be like on a world like that, perhaps other things would allow upwellings of hot minerals and nutrients, like volcanos or something

I wonder what the ramifications of accidentally seeding a planet with life that successfully becomes an invasive species there would be, like, politically.

nothing, a bunch of stupid yelling. Science would suffer horribly and in memory years later it would be understood and delt with the correct weight, but at the time, no, politically no one would do anything but whine.
honestly if that happened on one of the moons in our solar system it’d be a relief, imagine the Fermi Paradox if we knew life was so common it happened twice in our solar system

Yeah but like, what would the whining be about specifically?
