melodysheep is an incredible creator. The highlight of this video is noticing that matter only accounts for 1/3 of the entire runtime of the video (which, being on a logarithmic scale, means that matter itself only exists in the universe for an indescribably short amount of time). As someone who lives in the material world, made of matter, it is mindboggling to me that we could be so shortlived and that in reality, the universe after all matter is gone is still just being born.
I am but a collection of matter channeling energy that I do not understand or comprehend, but feel and know. I suppose it’s the reverberated universe I can call my soul. It’s my connection, which is different than others. Sometimes I think it’s stronger.
Like the horses running from Mt St Helen’s before the eruption, I’ve spent a lot of time trying to open up for different signals. So far so good actually!
This is a video montage with voice overs, but the salient information is displayed in updating text, which very soon is out of sync with the video montage and voiceovers. There is no need for this to be 30 mins. Better info consumable much more quickly without the neato irrelevant visuals here.[1]
Whatever you do, avoid the award winning, amazing, and wordless Qatsi trilogy.
Although the third one while enjoying psilocybin in a theater was beyond the usual cinematic experience…or maybe don’t click on links submitted by users with handles like “thunderbong” expecting a TED talk.
The "neato irrelevant visuals" is why I actually watched this video unlike so many others posted on HN. I'm not going to read through all that text, so this video was, to me, the best way to deliver the information in an interesting and engaging way.
The video doesn't follow the timeline. The video and voice over is still displaying and explaining about white dwarfs after all the stars have burned out, including red dwarves. It looks pretty, but it's incongruous and doesn't fulfill what the title promises in that it doesn't follow its own time lapse.
Here's one[1] that actually makes sense in only 9 mins, albeit without the trendy soundtrack. Here's a Kurzgesagt[2] that gets pretty close to the subject.
White dwarfs will be hot for eons. Long after other stars burned out. So if humanity find a way to live through a red giant phase of the sun, then it will have plenty of time to watch how Universe loses its starts while circling the white dwarf sun. Pretty optimistic. The only trouble is how to not become thrown out by a passing star. We need some means to shoot down those.
> White dwarfs will be hot for eons. Long after other stars burned out.
Red dwarfs are other stars that will last much, much much, much longer than white dwarfs, and it is red dwarfs that will be the final star type in the dying Universe.
This is what I am talking about; this was some video editing major's project, and while it looks and sounds pretty, the content is so bad it is teaching falsehoods.
"Barrow and Tipler estimate that it would take 10^15 years for a white dwarf to cool to 5 K;[11] however, if weakly interacting massive particles (WIMPs) exist, it is possible that interactions with these particles will keep some white dwarfs much warmer than this for approximately 10^25 years.[10]: §IIIE"[1]
Red dwarfs, I believe, can live for tens of trillions years, which is 10^13. And some of them will become white dwarfs.
A white dwarf is a dead star. The only light it emits is residual thermal energy. It may take a very long time to cool entirely, but in only millions of years it will effectively be so faint that it is invisible. Though a white dwarf was once a star, it is no longer when it reaches the white dwarf stage, because a star is defined as any massive self-luminous celestial body of gas that shines by radiation derived from its internal energy sources. A white dwarf has no energy source. Any remaining energy that it has is only remanent heat. White dwarfs do not shine; they glow.
A red dwarf, on the other hand, will produce and emit light via hydrogen fusion for 10 trillion years or longer before burning out and becoming a dead star... or white dwarf, only faintly glowing for millions of years due to residual thermal energy.
The last stars in the Universe will be red dwarfs, and even red dwarfs from the early Universe will continue to shine far, far longer, trillions of years longer, after all other stars have died.
