Alien civilizations have not visited Earth and never will, physicist claims

“There is a silence in the night sky that has bothered me for as long as I can remember.”

That line, attributed to Richard Feynman, lands because it gets at a simple, stubborn feeling. The sky looks full. Stars crowd the darkness. It seems reasonable to think someone else should be out there, and close enough to find. Yet the deeper physicists look into the laws that govern the universe, the more that silence starts to seem less like a cosmic riddle and more like a built-in feature of reality.

Human intuition is not much help. It developed for ordinary distances, daily motion, and short-term survival. It did not develop for light years, relativistic speeds, or timescales longer than the history of civilization. As Feynman puts it, “When you take that human intuition and apply it to the scale of the universe, it doesn’t just fail. It snaps.”

That mismatch sits at the center of the story. Five barriers shape the quiet: distance, the speed of light, propulsion, biology, and time. Taken together, they form what Feynman called “absolute walls that prevent civilizations from ever meeting.”

Physics and biology indicate the space aliens aren't coming and we aren't going to them.

Here's some Gram Parker for those of you waiting for the UFO's.

Did anyone say they wanted to go there to find aliens?

“NASA’s Perseverance rover has discovered potential biosignatures—the strongest evidence yet of ancient microbial life—within a rocky sample nicknamed “Cheyava Falls” in Jezero Crater. The sample contains organic matter, carbon compounds, and “leopard spot” patterns likely formed by ancient microbes, though geological processes cannot yet be ruled out.

Doesn’t really sound like what we’re talking about here.

They’ve been here.

When they see how we behave they lock their doors and move on. Can’t blame ‘em.

I have heard some theories that planet Earth is infamous throughout much of the universe for most of it’s inhabitants being prone to great violence and administration thereof.
The present result being a virtual Quarantine from other galaxies and universe swarms. No one knows for sure.

With a broken bathroom they will never make it. Can’t recycle the urine into drinkable water.

The word “administration”.
Should be “admiration”

My phone keeps trying to fix it for me.

As soon as Efrem Cochran gets that warp drive working, they’ll all be knocking on our door.

>> Can’t recycle the urine into drinkable water.

So drink it as-is, and let your kidneys sort it out. Until they crystallize over and clog up...

It’s not beneath some “scientists” these days, or at least their handlers, to phrase things in such a way that those with the money to fund the scientist’s research will perk up their ears with interest.

This is right on the money. The universe is too vast for us, or non-earth aliens to visit each other. It will never happen.
