What If We Are Alone?

A spooky exploration into the notion that there is no alien life, and we are utterly, completely alone in the universe.

Happy Halloween week everyone! In celebration, there will be new videos on this channel on spooky science topics every other day through Halloween. And, since I came up with more spooky scripts than I could possibly make into videos in a month, we will usher in Spookvember with even more!

The freakiest part about us potentially being the only life in the universe is that it puts the responsibility of keeping life in the universe entirely on our shoulders.

[emmitbrown]

If we're alone, there's really 2 reasons. We're either the 1st, or the last. Fun to think about.

[brennaguiniga]

Even if we aren't alone, the universe is so vast that we might as well be.

[jayvee]

It's just so bizarre that we're not in unimaginable pain constantly, and we have this remarkably coherent consciousness

[richard_d_bird]

well if no aliens show up in the next 10, 000 years i'm going to start feeling concerned

[ulicadluga]

The fact that we see the next large galaxy as it was 2.5 million years ago, means that we can only see how that galaxy was before our species began to walk upright.

[gabrielsurman]

If this is true, and we are alone, even though there’s no way to verify that but just in case, I love you guys, and it’s an honour to share this remarkable planet with you.

Edit: and the vast quantities of other incredible organisms, from the amoeba to the blue whale.

Every few months or so, I go down the space rabbit hole on Youtube. The sole idea of a universe with stars and planets is too much to actually wrap my head around.

[Bigdaddymittens]

Never thought we were alone, but I think the universe is so big that seeing another life intelligent form is just very unlikely. We've really only scratched the surface and speculated.

[skbee]

People tend to talk about lonely universes. However, I find comfort in the fact that I have you guys, everyone reading this comment, my family, my friends, and everyone else. Us humans as a species may be alone, but we are not some homogeneous hivemind. We are never alone.

[mapled_syrup]

If we are alone in the universe, then im glad we're alone together.

[sanilrover]

Somewhere out in the universe, an alien life is thinking the same

[arcturus]

Most likely scenario: we are not alone. But civilizations are separated by such vast distances of space and time, and the laws of the universe are such, that no matter how advanced or intelligent, they almost never make contact with each other.

[IrishCarney]

The truly terrifying thing if we are alone is that it means that the universe is extremely HOSTILE to any life (let alone intelligent life) to a degree that it is nearly impossible to exaggerate. It's not just that we are lonely in an empty spooky void, it's more like being in such an extremely dangerous environment that, regardless of intentions or none at all, it's the equivalent of a haunted house or the building in the movie "Cube" where everything around us is trying to wipe us out.

[adamesd]

Can you imagine if we are alone in the universe, that life only happened on our one planet, and then we go and blow up this planet and end life and even the possibility of life? This would be tragedy at an incomprehensible level.

[thecat]

If we are alone and we’re the most advanced lifeform kicking around trying to make our existence known that is pretty depressing, I think I’ll rewatch Prometheus now.

[FubarMike]

The most terrifying scenario is if the voyager probes smashed into a wall at the edge of the solar system that turns out to be a screen projecting the rest of what we thought was the rest of the universe

[youaremopped]

The universe is relatively young so even if we are somehow alone, it doesn't mean we'll necessarily be alone forever.

"Beyond unlikely" is the best way to describe life magically appearing in a vast vacuum of debris and radiation.
