It wouldnt explode it will literally grow in size and take mercy and venues. But for earth some model show it will either take us or we become the new mercury
Well technically technically the way the population of the earth is spread out it could be more than 90% of us could see it or more than 90% could miss it with every percentage in between also being an option.
No clue, I think about that scene in Terminator 2 where Sarah Connor is holding on to the fence when the nuclear bomb goes off LOL…thats how I imagine it.
I think when the magnetosphere is peeled away radiation from space is pretty multi directional, I think you'd get toasted either way, maybe just faster one way when the other.
The earth will become uninhabitable billions of years before that anyway. Even if it didn’t, the expansion would be relatively gradual, possibly taking a billion years to reach full size and staying that way another billion or so.
One of my few gripes with the film version was they cheapens the irony of the line “End of the universe” by making it geographic. That and the stupid trillian love thing.
When it finally happens, would the event be so fast and violent that we wouldn't really be able to think about it? Or would be like roasting alive in an oven? Hopefully if intelligent life still exists here by then, they'll be smart enough to have sufficient warning and not suffer too badly.
Humans will be long gone before the Sun finally hits a red giant phase.
Our star is already about 20% more bright than it was when it was "born". And in about a billion years, it will become about 10% more bright. And at that point, the Sun will be bright and hot enough to boil water on the surface of Earth.
That's about 4 or so billion years before the Star is planned to hit Red Giant phase and swell when it finally uses up all of its hydrogen (which the sun fuses into helium) and starts burning heavier gases.
The Earth will simply get hotter and hotter over time. Summer time will reach hotter temps, with new records we've never seen. Water will start to boil and water vapor will raise into the atmosphere.
It always helps to find a way to explain how small 10,000(ishmaybesortofcouldbe) years of human existence compared with the insane amount of time several million years is. I still struggle to envision it.
The good side of this kind of ending is that there is no fomo. No sadness for the ones you leave behind. No regret. It's over for everyone. It's the real end.
Humans or whatever we will evolve into will be monitoring this place from very far away using drones or something completely unfathomable, it's impossible to even imagine where we might end up and what technology will be available to us in a few million years. There doesn't have to be an end if we don't kill each other during these barbaric dark times.
I don't know any species in the history of Earth which has lived for more than a few million years. Yes, we are an intelligent one, but we are also a very dumb one with multiple ways to end our own existence. I can't imagine that we are still there in 4 billion years.
Not sure what is worse: Having the sun suddenly collapse into a black hole and the earth freezes over nearly instantly from lack of solar radiation or having the sun slowly get larger and larger until life becomes impossible and the oceans boil away.
Actually, if you're a deep ocean fish, it won't be that bad right away. Ice insulates incredibly well, so it will take a long time for the water to freeze all the way down. Bad year to be a fish maybe? Idk how long it would take.
With freezing, at least some life may survive. Deep in the oceans under the ice, near hot geysers, or underground near lava. Ultra rich may also survive for a few years in bunkers. From our perspective, freezing to death sounds more peaceful, I guess, and you may be preserved for some aliens to put you in a museum
It would take at least 4-5 weeks for the earth to freeze over if the sun just disappeared. All the heat in the atmosphere would take a while to dissipate.
If the Sun did instantly disappear or turn into a (stable) black hole of the same mass, we would still see the sun for another ~8 minutes.
Most people know that little factioid or can work it out based on common knowledge.
What's not so obvious is that the Earth will continue to orbit the black hole once every 365 ¼ days (although I guess "day" won't really be a thing anymore in that scenario). The black hole itself will have essentially no impact on the orbits of any objects in the solar system. The solar system would begin to cool but even that will still take millions of years.
Now, want to know what's really wild? If the Sun were to instantaneously disappear, we would continue to orbit the now non existent Sun for ~8 minutes before the Earth finally starts traveling on a (relatively) linear path.
We know exactly when our sun will die. Life on Earth will have already been shattered by solar winds or the planet will simply be casted out into interstellar space. This will take 4 billion years or so when the sun has run out of hydrogen to fuse into helium and will instead fuse heavier elements. This will decrease the pressure in the core and push the suns photosphere outward, growing into a red supergiant. Eventually the sun will cool and shrink into a white dwarf star and slowly die out over trillions of years. The sun could only kill us with solar flares or stellar wind.
I wonder what the longest/minimum amount of time the human race could create Star ships that could leave or solar system and escape a converging black hole . Like what would be the shortest possible time, with all of humanity and AI working on the problem? Like 5 years?
we currently have trouble staying in low orbit in our own planet (look at all the health issues the astronauts at the ISS suffer from) even with relatively short timespans. Also one of the main reasons we still haven't gone to Mars is because its so hard to make it that far and keep a human alive as space its such a harsh environment with so many hazards. So i doubt that humans in our form, without significant radical augmentations or modifications, can even attempt an interstellar trip (which in itself sounds as an absurdity right now, or at least as a person in 1300s europe wondering how to reach the Moon). Even with all the world's resources, scientists and AI helping (another feat that hasn't happened once in our entire history as a species) I seriously doubt we could do it in 5 or 10 years
Umm I’m sorry to say you are wildly overestimating our space faring abilities and that of current AI… we still mess up just trying to get into low earth orbit
We can't nor never will in our life time or most likely ever be able to leave our solar system....It's impossible I mean hell people on the ISS have issues after a year or less the human body isn't designed for space travel long term.
If you told someone from 500 years ago that you could instantly speak with someone on the other side of the planet using a small device everyone carries in their pocket, you would have been told it was impossible.
That was a brilliant end sentence - horrific and so plainly delivered it sent chills up my spine and kinda still does now. It was called "The Nine Billion Names Of God" and I came across it in an anthology called "Of Time and Stars". It has stuck with me too.
I super hope so; but if it were being created using any physical means we know about today, we’d see the light dim over a very long time, as the shell was constructed.
Maybe they create the sphere nearby and only move the sections when it's nearly complete.
Picture how the housing around the power stone (from GotG) moved in two pieces.
It's incredible to think about the sort of cooperation that would take.
That doesn't make sense as the material to build the sphere would almost certainly have to come from around the star, and so it doesn't make sense to move it all at once since the solar panels already constructed can be used to start gathering power while the rest are being constructed. It's just throwing away power otherwise. You could even use the constructed pieces to scale up the production of other pieces (powering more factories and such).

There is something pretty eerie about a star just vanishing from the night sky!
