According to the drake equation we’re looking at at least a few million planets with at least ordinary carbon-and-water-based life in this galaxy alone- and in such an unimaginably huge place as even the galaxy (never mind UNIVERSE) there’s bound to be at least 2 of everything, including sentient species.
Yet we see nothing. Even if FTL is impossible, we should be seeing signs of more advanced civilizations (starts shifting due to Dyson swarms etc). Something in our understanding is very wrong, and most of the options are horrifying, in their own ways.
Nah. The distances are too vast. Even if you could touch 1/4 of light speed then that means to get anywhere you take light years and x4 and you start to see the issue.
Then there’s the time dilation thing. Suppose you do see some evidence…so u fly towards it. Only in the time it takes u to get there the civ is gone.
There are a few unexplained phenomena in the universe that physicists do little more than shrug their shoulders at. Any of them could be evidence of other life, and there are proposed theories suggesting as much. We can’t prove anything definitively because we’re too limited in how far we can go towards explaining the unexplained, but I’d say there’s an asterisk on “nothing”.
This would be what we called a “gas pack” - which I think was a brand name, it’s been a while.
What I would have considered a ‘dewer’ was a vessel meant to hold cryogenic liquid that was not under pressure, basically a thermos of any number of sizes. And then there are these large vessels that can hold pressure. Some are only meant to have minimal pressure, because the user is interested in the cryogenic liquid inside, so the pressure is like less than 20psi if memory serves. The unit that is being referred to in this post was the aforementioned ‘gas pack’ that has an extra set of tubing that is wrapped in a around the inner of two vessels, so that liquid can gasify due to the heat exchange effect this coil provides, and allow this gas to be used by the customer. These are usually vented around 250psi, again if memory serves, so that the vessel doesn’t explode, ha ha. You can keep it from venting by isolating this gasification line, but that also reduces the convenience. It’d probably be best to store the vessel in a temperature controlled location to minimize the the chance of overpressurization.
Wow, that’s awesome. I’ve been thinking a lot about the scale of the universe and how cyclical it is.
Take a scaled out view of our solar system and then compare it to a molecules composition (the atom or group of atoms surrounded by protons and neutrons) and the similarities are just uncanny.
Like this image, what’s to say that we aren’t just part of a molecule making up the chemical composition of something far larger than ourselves. An ant has no concept of the vast empty space between the United States and Europe, we know that is the case between solar systems but our actual understanding of our relationship in space is limited.
P.S. look at the patterns of discharge of electricity in wood/paper/stone and then look at the patterns of the Grand Canyon. They’re the same! And the Grand Canyon is the only formation we have that exhibits this quality, which makes it extra interesting.

Nah, the planetary model of the atom is outdated. The quantum model doesn’t look very much like a solar system.
