Reaching Type One Civilization: Predictions and Possibilities

[hey.like]

Future it will be beauty enough

Future, it is a bigger ideal in a goodwell men, whenever by works and to compete with war, naturely, future it will be beauty enough.
Nature, the action will be down this beauty dream , perhaps in some another wise development in another stars.
Dream , beauty and totem for to peace in nature and another wise and relation well in another stars.

Using 20,000, the number of stars reached after 100 million years would be (max) 219,999. That's rather more than the number of baryons in the universe.

I did 2 to the 100th power and the figure was 39,614,081,257,132,168,796,771,971,975,168 which is 39 nonillion, 614 octillion, 081 septillion, 257 sextillion, 132 quintillion, 168 quadrillion, 796 trillion, 771 billion, 971 million, 975 thousand, 168.

and that's only to the 100th power... I can't imagine 2 to the 19,999th power. don't think there's a computer powerful enough today to calculate to that number.

Mersenne primes

Running in background mode on my PC is a program called Prime95. Along with thousands of others, I am trying to find the next Mersenne prime. We do this by running this small program; while it's not a screen-saver, the principle is very similar to Seti@Home, which is used by millions to look for signals from ET.

The largest Mersenne prime found so far - not by my computer - is 2^13466917-1, the 39th such prime. I see that a possible 40th has been found (also not by me), and is now being verified.

Clearly my humble PC can handle numbers much larger than 2²⁰⁰⁰⁰, and I've no doubt yours can too.

Perhaps all the real aliens are made of dark matter, or even dark energy? Perhaps we aren't where the action is at all! Maybe there are billions of Type III analogue civilisations in the dark matter halos of galaxy clusters, all communicating via a CDMA-like encoding of neutrino streams, and tapping into dark energy for sustenance.

I agree with you here, Nereid, and practically all the time. But would it be possible you have been reading too much Philip K. Dick novels?

Dark energy is hardly science fiction, although no less intriguing and full of mystery for being real science. To give you a little benefit.

IF they even are composited and composed of dark energy where would -- (I'm not sure if I can even comprehend this), where would or how would the beings oppose the self-attraction of matter and causes the expansion of the universe to accelerate? How could they even live on any suitable environment and what would their planet even consist of in elements?

Made of dark energy, they wouldn't be planet dwellers, but woul live in outer space. Probably their scale would be far from ours - either vast in intergalactic space or tiny in other parts. Speaking of sf writers, Greg Egan's novel Shild's Ladder has a portrait of life like this.

maybe it's seagreen meta-neutrino-ware!

Jeebus, SelfAdjoint -> I must make an effort to read more scifi

There are surely many, many flaws with my crazy ideas However, they might have some value as metaphors; if not 'dark energy', how about 'seagreen meta-neutrino-ware' (which won't even be conceived of for another 5,000 years)?

The wise palace advisor to the Yellow Emperor (who died over 5,000 years ago now), Archimedes, Newton, Maxwell and Gauss (even Einstein? ) could all have had not the slightest inkling of 'dark energy', so who knows what cutting edge physics will be into 5,000 years from now?

 

[selfAdjoint]

I think Einstein understood all too well about the effects of a Cosmological constant. Recall that he had it in his original equations because they predicted an expanding universe without it, so he very carefully balanced what we would today call negative dark energy to keep the universe static is it was thought to be at that time. When Hubbel later showed the universe to be expanding he dropped the constant, calling it his biggest mistake.

Einstein liked to play around with his equations to see what they would do, and I am sure he discovered the accelerative properties of a positive dark energy. He would probably just have chuckled and circular filed those calculations, for who could believe such a folly as a runaway accelerating growth to the universe.

 

[Nereid]

'greatest blunder' - not?

I remembered the 'greatest blunder' comment, but hadn't thought through what must have gone before in order for the comment to have been made in the first place (and certainly I didn't to any research ). So it's clear that Einstein wouldn't have found 'dark energy' alien.

In the Great Shapley Supercluster Library, there is a one paragraph entry (in a dusty tome, on a high shelf, in one of the 25 billion 'back buildings' rarely visited) describing a curious observation about a barely detectable deviation from thermodynamic equilibrium of some mote in the baryonic part of a minor galaxy in the outer regions of the Virgo cluster; the para concludes (translation) "probably just another observational error"
