are you shocked at how big the universe is?

The universe is so big it's bigger than what we can observe

I remember finding about this in 5th grade and being so scared that Earth is not even visible and super far from being it. I also used to think that we're the only people in the entire infinite universe

Yeah it is weird hearing about how big the whole universe is. It makes you think,

Makes you think what?

What if there are aliens living amongst us now? Like wearing disguises or smth? I mean you don't know everyone! (sorry for my weird idea)

It's weird to think that we are supposedly the only ones in this huge universe.

Actually current estimations put the number of galaxies at around 2 trillion (in the observable universe)

I'd recommend youtube channel SEA for space stuff:

another good vidoe for the scale of the universe

LOL I should proof read before I post, I meant it makes you think about how useless Earth is. We don't really mean anything in the universe. We're just there. Yeah I read somewhere that the government know Aliens exists and talk to them, but that could be a lie. I think Aliens have more better technology, they probably know about us but don't care because they have their own alien life.

I believe there smarter and more stronger than us, but look something like a upgraded versions of humans, not like those green black eye things in movies. But they could look any way too, depends on how there planet is. It could affect how they look, like how the weather is, if there's water, etc.

IDK I just really like Aliens, they probably think of us as Aliens, IDK why we call them Aliens but we just do.

Yeah, true. I've seen many sci-fi aliens calling humans "primative" lmao. But that is most likely very true.

Same, but there are many different races probably. I have a feeling with different environmental things they may face, that bodies would be a lot different than here on Earth because living things have to adapt to the environment.

Yeah, it's a pretty interesting subject. It's scary to think that there could be life on other planets but considering how very, very, very small we are compared the universe, it's very impossible that life doesn't exist on other planets.

Although we get the feeling of how useless and small we are compared to the whole observable universe and whatever is beyond that, we are at least aware of that.

Most of the matter in the universe aren't "alive". The bacteria in your gut flora is special as it is at least alive compared to the rest of the universe (if we are indeed alone which is a possibility). It will just exist till decay eventually (if proton decay is really a thing).

On the flip side, we are universes by ourselves. The amount of other beings living in our skin and in us is also mindblowing. When an animal dies, lot of other smaller beings die with it. The big universe is daunting, but the small scale is also eye opening.

That's cool, but I wonder if humans could be wrong, like there could be more than 2 trillion galaxies. We don't have the technology to know.

Well we will never know whats outside the observable universe, as it is too far away for the light to have had enough time to reach us.

gives a good sense of it

The theory of cosmic inflation speculates that the entire universe is 150 sextillion larger then the current observable universe. Keep in mind that the observable universe is 93 billion light years across, the scales are such that its not really possible to grasp.

Nope. We barely know 1% of what's underwater here on Earth, imagine outside of it lmao

Woah I was recently watching videos like these, it's so interesting and scary at the same time. Black holes and titan stars, like Stephenson 2-18, scare me a lot. What if somehow they devoured/destroyed our solar system?

I also want to know where other species of beings live and what are they like (Dune definitely hasn't influenced me in this )
