Population growth compounds, though. Once you’ve colonized a million worlds, the next million would come in a fraction of the time of the first million, and the next 2 million in less time than that, then 4 million in the same time as before, etc. Like grains of rice on a chessboard. Totally feasible to fill a galaxy if FTL travel is achieved.

More likely - FTL is impossible so each species is stuck in their own solar system.

If FTL is a thing, that’s OK with me, many good stories include it and I’d miss them.

Yeah, it's really hard for the human brain to intuitively grasp exponential growth. Anyone who says a galaxy is "too big" hasn't actually run the numbers on that.

FTL is impossible so each species is stuck in their own solar system.

FTL is in no way necessary to allow for interstellar colonization to proceed.

GreyEyedGhost,

The number show that with the right technology, meaning ships can accelerate to 0.05c and we can convert asteroid fields to self-sustainable habitats, a civilization could colonize the Milky Way in about 200,000 years. A blink of the eye in cosmological time scales. FTL isn’t necessary, except perhaps for cohesion.

Baseless speculation. Might as well say demons are in the earth hiding.

Or - and that is just hypothetical- they want to show it to their colleagues smirking and saying “get a load of this guy”.

Farmdude,

I can tell have this way about you. It’s so on the money. Your money

mkwt, w Open journal question regarding Cosmology paper

A prestigious college downloads the paper. What are the possible reasons?

Same reasons anyone else would want to read the paper? Abstract looks germane to someone’s research topic there?

Farmdude,

I was just gaining insights. Thanks

tunetardis, w Sharper than ever: New algorithm brings the stars into greater focus

So ground based observatories have long benefited from the development of adaptive optics. That's basically where you have a small mirror that is synced to the movements of the upper atmosphere and essentially cancels out the shimmer that makes stars twinkle to the naked eye, bringing them into a sharp focus more like what you would get from a space telescope. But the tech can only achieve this feat over narrow patches sky, meaning wide field observatories were left out. I think that's what they're talking about here? You can't get much more wide field than Vera Rubin.

alyqz,

I believe this is a new deconvolution image stacking algorithm that can easily be run in hardware. It should work with any observatory. The math is far enough above my head that I can’t be sure though.

It would be cool if this makes it into software that people could use at home. I would love to see what amateur astrophotographers could to with it.

tunetardis,

Oh that would be cool!

Hopefully, this new algorithm is not overly taxing. The amount of processing they’ll have to do to keep up with Rubin must be staggering. It’s got what, a 3.2 Gpixel camera mapping the entire night sky every few days. And then all that data has to be processed across the timeline of past observations. I wouldn’t be surprised if the computational demands are what kept it from becoming a reality until now.

SanctimoniousApe, w Sharper than ever: New algorithm brings the stars into greater focus

What kind of alien god is looking on from deep space in the upper right? I see two eyes, a mouth, and the dark shading varies just enough to look vaguely like a head.

I’m starting to think maybe I’ve had a few too many arguments intense discussions with alien conspiracy theorists…
