You don’t spend your day in the deep sea next to the sun and then sit in a fridge with uranium in it? Weird

That panspermia from tardigrades hypothesis is crap. Doesn't explain prokaryotes, archeae, endocymbiosis, etc...

OK they can live in extreme conditions, but in normal circumstances almost everything (insects, plants, other water bears) kill them

*but will it blend?*
Universe_Cat3 (5 месяцев назад)
Except they get killed in millions daily because they only have defenses that work on nuclear weapons. They can't even thrive in these conditions, just withstand it for a longer time than other animals

TARDIS blog is good if you are interest in finding escorts in shitty countries.

No, they are not extremophiles. The term is reserved for those who have their habitat in extreme environments - not "just" support extreme conditions. Get it?

I think it would be highly that tardigrades can seed another planet with life because eventually they will have to eat, and if what they eat here on earth is moss than this is something they have co-evolved with and will not find elsewhere. What do you say?

Tardigrades are most definitely not godmode builds. They prepares for things that will never happen.

Tardigrades are not extremophiles. They do not love extreme environments. They can tolerate extremes but they do not thrive in them. True extremophiles thrive in harsh environments.

This episode didn't say anything about how Tardigrades are key to navigating the Mycelial spore network. Thumbs down!

Tardigrades aren't extremophiles. They can't survive in harsh environments. They can persist. There's a difference. If you can survive, you could live there all your life, get food, and be fine. If you can persist, you'll still die, it'll just take a long time. And a tardigrade will still die in space, it'll just take a long time. Also, tardigrades are kinda stupid. Yeah, they can survive armaggedon. But they can't survive the most basic things that they'd actually have to deal with on Earth, like... a worm. They can survive exotic things that are impressive, but they can't survive simple things that would actually be useful. Like how a honey badger can survive a bunch of bumble bee stings.

how do they protect their dna and there telemers?

So we've sent some into space.. What if some of them were just left to drift and that's how the massive one in ST: Discovery came to be.. I mean they actually mentioned Elon Musk in it so this could well be the explanation for the big guy
4c00h (9 месяцев назад)
It's most likely they came from space in the first place and ended up here
TrickShotKoopa2007 (9 месяцев назад)
0:50 actually wrong they can not survive in harsh environments. Sure they can chill there but if they are not in the area they need to be they will eventually die, so no. They are not Extremophiles.

Waterbears are low-tier garbage. If you want a good survivalist class, I suggest the Rat, the Roach, or—if you're feeling really extreme—you could try out an Archaean. Also, you even admit "there's no way that would be useful on earth!" Yes, you're right. They're resistant to everything BUT what would kill them. Yes, they can survive for a long time in space. But they WILL die. It just takes a long time. They're killed by the millions just on accident from snails, slugs, crabs, etc. Not to mention their cannibalistic.
