Did we solve the Fermi Paradox?

[dennisw]

I think the claim might be a bit premature but we are getting closer to finding something.

Was just now having a look around the SKA's website ..

www.skao.int/en/explore/big-data

If there's anyone out there and if they're broadcasting on any frequency, this instrument should spot'em. 👾

[dennisw]

Maybe they have found us;

If they have, we don't see any signs and omens.
Afaik, none of these expected signatures do we see  ... 🛸

PHYSICAL CONSTRAINTS ON UNIDENTIFIED AERIAL PHENOMENA
Abraham Loeb and Sean M. Kirkpatrick
lweb.cfa.harvard.edu/~loeb/LK1.pdf

We derive physical constraints on interpretations of “highly maneuverable” Unidentified Aerial Phenomena (UAP) based on standard physics and known forms of matter and radiation.
In particular, we show that the friction of UAP with the surrounding air or water is expected to generate a bright optical fireball, ionization shell and tail - implying radio signatures.

I never ever thought about such friction. If this occurs, I wonder if it's a problem for the craft's users. What might they do, what technology might they employ to counteract for this problem. I wonder how this counter-friction tech might manifest itself to outside observers.

If we are detecting them in deep space they are not yet UAP we will have to wait until they enter our atmosphere for that.

Good points, those. 👍

We've been detecting meteors burning up in the atmosphere since the early days of radio. If UFOs were up there making radio shockwaves, we'd 100% hear them.

SDR could pick them up too. But, needless to say, meteors are not top of one's watch-out-for list when "out in the sticks".

I just now stumbled upon this reference to an air lubricant system for ships at sea. Perhaps ufos/uaps have some analog system to reduce friction?

Here's a Chinese system which both lubricates and propels.

In addition to generating thrust, the laser also vaporizes the seawater close to the vessel, creating bubbles on the submarine’s surface and reducing water resistance. This phenomenon, known as supercavitation, could potentially allow submarines to travel at supersonic speeds underwater.

[dennisw]

I have seen some of these air lubrication systems and they do show promise.

[Ian Thomas]

Navantia's S-80(?) submarines are powered by ethanol fuel cells. I recall they have a special pumps to expel the CO2 generated in the form of micro-bubbles into the surrounding seawater. The advantage being that tiny bubbles don't make a lot of noise in the process - an important thing for a submarine!

Sounds like the above systems might be derived from the Spanish technology?
