Uh . . . I'm pretty sure that stars don't talk. (talk) (please sign your comments with ~~~~)

And squirrels don't ring. This comic can be absurd sometimes. 17:05, 22 October 2018 (UTC)

Why are you so sure that stars don't talk? 18:23, 22 October 2018 (UTC)
I think it was a NOVA doco where they describe the inner workings of the sun and how hydrogen atoms, photons, plasma, and magnetic flux interact, and it sounded a heck of a lot like the function of neurons and signals in the brain. Maybe I was just high, but I got to thinking that, with photons from every star in the universe connecting to every other star, the stars are in constant communication with eachother in some sort of neural-like network with each star having it's own neural-like network complete with it's own sentient thoughts (albeit probably far outside the realm of our imagination).

Obviously, stars, being in vacuum, don't talk in classic acoustic way. But they emit lot of light, which includes radio emissions ... and remember that properly encrypted signal is hard to recognize from random noise. -- Hkmaly (talk) 23:05, 22 October 2018 (UTC)

Stars can talk but usually don't. Maybe because they are under a lot of pressure ? 08:45, 24 October 2018 (UTC) BadJokeNinja

Am I'm the only one, who is reminded by the beginning "...AAAA" and the ending "EEEEEAAA..." to the "The Man Who Fell Sideways" comic?-- 12:17, 24 October 2018 (UTC)

"a small Red dwarf has a lifespan of about a trillion years." A trillion years? Any source for this? The universe is around 14 billion years old. 13:32, 24 October 2018 (UTC)comicreader

That doesn't mean it's that old now. It means it will last that long, which means it's a relative youngster at this stage of its life. I'm sure a trillion years is a very general estimate for its lifespan, which is highly dependent on its mass. As for the source of this estimate, it's probably well-sourced on Wikipedia that serves as the source of much of the explanation's current content. Ianrbibtitlht (talk) 13:48, 24 October 2018 (UTC)
And click the Wiki link for Red dwarf in the explanation. You will read: "...Red dwarfs therefore develop very slowly, maintaining a constant luminosity and spectral type for trillions of years, until their fuel is depleted. Because of the comparatively short age of the universe, no red dwarfs exist at advanced stages of evolution." --Dgbrt (talk) 18:34, 24 October 2018 (UTC)
