Can the Fermi paradox be resolved through the assumption that interstellar travel realistically is not possible?

Can the Fermi paradox be resolved through the assumption that interstellar travel realistically is not possible?

No. Evidence can be transmitted with radio waves.

It's because of interstellar warfare and relativity bombs. Alien cultures want to be stealth so they encrypt their signals.

Pic Related, but it could also be that reality itself could be manipulated and maybe aliens are doing this instead of travelling within our universe. Kind of like the matrix or something.

On a sidenote: Anyone know how much time dilation a person would experience close to the event horizon of a black hole?

They're using directed radio waves to communicate that exclude earth

Assuming those radio waves dont get distorted enough to be unreadable after hundreds to thousands of years traveling through a universe filled with fusion reactors that convert mass into pure EM energy. Theres only a handful of stars our earliest transmissions have even reached.

Assumption 2 is flawed

Bitch we can barely detect radiation originating from distant stars in our own galaxy, you think a signal originating from an alien civilization would have an intensity great enough to be detectable? Any civilization with a radio telescope pointed at our sun would see our communications as noise and filter it out.

For extraordinarily short distances (in terms of interstellar distances.)

>close

Would depend entirely on things you don;t state, such as "What do you mean by close?"

I guess my question should have been how close to an event horizon do you have to be for any significant time dilation to occur?
