    When an asteroid hit, it will have a hole there and those aliens will go out to explore, but they will die.

    Wait... Off in distant space... Possibly Eldritch and due to the long isolation could develop hyper-aggression towards other species... AND they can't use metals so they would have to build out of biomass... Are you telling me Tyranids might be real?

    Meanwhile, some more advanced aliens discuss how on rogue universes, the beings who live in it might think there's nothing beyond it, and can only observe as much as the speed of light in it allows them to.

    2 of Saturns Moons are Frozen & have water under them Enceladus & Titan, also Jupiters Moon Ueropa  has water under the ice, SO it would just be easier to travel to them instead of trying to get to a Rogue planet

    It may be possible that they have no eyes considering there will be little to no light in their, meaning they may be dependent on echo location. Or something better

    Hey I love your content. Made me wonder : is there a theory that exists, saying that we could use the earth as a spaceship ? That we could heat it enough to sustain through the -273 degrees of space ? And that we could migrate to a new solar system ?

    거꾸로 우리는 대기권이라는 벽에 갇혀 살다 드디어 진화가 아닌 도구를 사용하여 대기권을 벗어났지만 아직 상위차원이나 대기가 없이도 오직 자신에게 있는 에너지만으로 생존하는 생명체에 있어서 한참 진화가 필요한 존재일지도 모른다대기권을 얼음벽과같이 뚫고 들어오기 어려운 벽이라고 생각하면 좀 더 광범위하고 분자구조나 결합에 대해 느슨한 생명체가 존재한다고 가정했을때 그 생명체가 지구를 지나쳤을지도 모른다...

    An interesting fact extrapolated from your Deep Sea video is the size of deep sea creatures. Whenever we depict aliens in movies, videogames or the like, they're always conveniently bipedal and around 2 meters tall. Well, since deep sea creatures typically evolve to beocme bigger, imagine discovering an alien species intelligent enough to communicate with, and their average size is something like 25 meters.
