The Physics That Makes Interstellar Travel IMPOSSIBLE
YouTube ^ | February 6, 2026 | Richard Feynman

Posted on 02/19/2026 1:56:56 PM PST by rexthecat

Richard Feynman’s physics reveals why aliens cannot reach Earth. From the absolute limit of the Speed of Light to the Fermi Paradox, discover why Interstellar Travel is impossible and why we are truly alone in the universe. …

Yes the problems are massive.

However these Richard Feynman and Leonard Susskind videos being slung out on youtube like the one you posted are likely fake AI slop.

The videos do sound just like those men but are manufactured. May be somewhat accurate in that AI learns content from their lectures and writings.

Certainly the headlines are pure garbage. It’s one thing to describe severe problems but another to say it’s an absolute impossibility for humans to ever do something.

Leonard Susskind is probably pissed that people are putting out this AI slop. Feynman doesn’t care because he’s dead.

I guess we need some ship that can reach warp factor nine then.

Anti-gravity propulsion? Already solved via Alcubierre, exotics materials and extreme electromagnetics.

Interstellar travel is absolutely possible, it will just take a long time and require a lot of energy.

The way we are doing it now? Correct.

But we haven't stopped looking for new ways to get the job done and we are wonderfully tenacious that way...

We haven’t gone to the moon, except in a studio. Which is why Neil Armstrong wouldn’t swear on a Bible he’d been there

First step: Get back to the Moon and see how things look from there :)

Captain Kirk can come along later.

Us being alone is mathematically impossible.


If we are not alone, wouldn’t that invalidate the Bible? It said the “Heavens and THE Earth”, as in one!

Heh.

I was thinking of you when I wrote post 17 above.

Figuring out gravity, beyond Einsteinian 3D space/time, is the crux of the biscuit.

Probably not “anti-gravity”... but space/time energy density manipulation that would either nullify or modify the inertia of a spacecraft. Would throw a wrench in the light speed limit.

Yup,I’ve seen a couple of his videos. What I didn’t hear him mention was nuclear propulsion. A few pounds of plutonium allows you 450,000,000 miles.

Why? Just because JHVH started here doesn’t mean he stopped with JUST here...

Never mind the tens of thousands of people with first hand knowledge.

No they didn’t. The Apollo missions were strictly compartmentalized. A handful had clearances high enough. Which is why Gus Grissom blew the whistle on the program to the public…and died for it.

The laws of physics are hard to dispute.

Gravity isn’t the problem. TIME is the problem.

I i keep up with that research. Putting wisfhful thinking aside betting with Feynman is still the way to go

Building 7 and the Pentagon are weird.

[ducking…]

Look up B-25 hitting the Empire State Building in 1945.

A nuke will set the atmosphere on fire.
Global warming will melt the ice caps by 2012.
Communism will work this time.
