Muh Fermi Paradox

>its pretty safe to say there is no life in our galaxy other than us
What makes you say that?

>we're definitely alone guys

200 light.year is not so far away...

We haven't even gotten started yet.

Humourous or deeply depressing.

There are some voidspots in the universe anon, like the Bootes void, Giant Void, CMB cold spot etc. The only reasons we don't see any life or graveyards and no sings of artificially things is because the distance is too fucking big in the universe, pic related, that's only the Milky way, there are estimated to contain 100–400 billion stars in this galaxy alone. So if we really want to find life and conquer this galaxy, we need FTL travel.

With out tech today we could barely detect a civilization on our level if it was 10 light years away.

Space is gigantic. We don't know if advanced civilizations are easier to detect, superstructures are a sci-fi meme. Colonizing thousands of planets is pointless.

Not to mention we already detected many signals we can't explain we just don't have proof those are aliens.

Because it's bigger than you think.

I always thought that time WAS linear (as in it always moves FORWARD, in continuum). However time itself is curved/bent in relativity (different speed). You can't go back.

Am I right?

>why has no evidence been discovered

Yeah, real mystery.

Humanity would really benefit if all retards like you were euthanized.

Do you fucking dumbshits really don't see the significance of life existing twice in one goddamn solar system? If that's true galaxy is literally full of life.

In case you don't think that the Fermi paradox is BS.

Look how small we are. By the radio waves get anywhere they have been distorted by interstellar medium

>yet we STILL haven't found any life outside of Earth?
Because we've literally just started to look. We've sifted through a cup of water from the Pacific ocean and complaining we haven't found any whales yet. For all we know there could be other life in our own solar system on Europa or Titan or Mars or some other body, we just don't know yet because we haven't even begun to look.

I did my dissertation on measuring the mass of the Milky Way, where I measured the radial velocity of the gas at different parts of the galaxy. I found that the rotation curve I measured dipped up and down quite periodically. This was talked about in previous studies and was very likely caused by gaps in the density of gas where I was looking, i.e. there was no gas in that area, corresponding to a lack of a spiral arm. Although this doesn't PROVE spiral arms exist, it was definitely a way of implying that they existed.

All in all, trying to answer your question here

>They don't line up with any of the projected arms in the *artistic representation* and nobody could draw any spiral pattern through these dots.
I'm quite sure we didn't extrapolate spiral arms from the STARS, we discovered spiral arms from the density of gas throughout the galaxy. Though I may be wrong and I can't be bothered to actually do any research to confirm my suspicions.

We've dipped a fingertip into the water and haven't immediately found conclusive proof, so we conclude the entire ocean is sterile
