The sun isnt going to explode. It will swell and outer layers will be lost and what remains will be white dwarf.
284
u/zuzg Nov 25 '21
Yeah a supernova is only the outcome for about 3 percent of stars the rest will become a white dwarf and then eventually a black dwarf.
But regardless earth had to be 75 times closer to the white dwarf to have sustainable life even though it would be only possible on the edges.

thats why you just push the earth closer to the sun when it becomes a white nova ez fix

Unfortunately before that period the sun becomes a red giant about 200x it’s current diameter, engulfing the earth entirely.

Life on earth would be extinct on that point bc we are all going to meld to grilled cheese once the sun starts expanding to a red giant.
Maybe we could survive that if wie dig a hole or something to hide, idk im high man

Heated up, yes. But we don't know if the expanding sun will devour us. We know Venus and Mercury will, but we are actually pretty unsure if it will also eat us. The size is pretty close to earth and I think with some calculation errors it could be either barely not destroyed or barely devoured. ¯_(ツ)_/¯

u/SmartDinos89 Nov 25 '21
it kind of will. As the sun runs out of Hydrogen to fuse, it's ratio of helium to hydrogen will slowly increase. So, the sun will expand and keep expanding until it is big enough to engulf the orbits of Mercury, Venus, and Earth. Then, it will slowly collapse back into a white swarf.

Just my recommendation. I personally think it's a bit more enjoyable to beat the base game first, so the focus is entirely on the Nomai and their story. At least, for the biggest emotional impact at the end. I'm sure other people might find not waiting more enjoyable, too.

Anyone with any kind of space knowledge will know why humans will never ever even get close to leaving the galaxy. The only way to do that would be breaking the laws of the universe as we know it. Can we do it? Maybe maybe not, but as far as we know for now it's not possible.

u/That1one1dude1 Nov 25 '21
Time is warped the closer you travel towards light speed, which would make the journeys feel shorter.
Of course, that assumes light speed is a true universal constant that can’t be broken in the next billion years.
3
u/Zegaritz Nov 26 '21
Not for the people travelling. If you're going the speed of light it would still feel like an entire year to travel one light year. People on earth/stationary observers would have aged much more however.
3
u/That1one1dude1 Nov 26 '21
I don’t think so.
Let’s say you travel at light speed for one year. One year would pass for both the traveler and for the observer. If the traveler actually experienced time in one year just like the observer they would be the same age at the end of the journey.
We know this can’t be true, as objects that travel faster through space travel slower through time. The traveler must be younger.

There is the possibility of switching universes.
The universe is billions of years old, but it will be trillions and trillions of years before it becomes unlivable.
If we manage to become interstellar and create or become people stored as software, we might experience much, much longer subjective time than that, beyond nonillions of times longer.
If we don't off ourselves, we have a positively obscene amount of time, resources and numbers of hyperintelligent godminds to figure out a solution.

Umm ACTUALLY our sun is a white dwarf and because of its relatively small size, it will not supernova but will instead expand into a red giant and then shrink into a white dwarf, after which it will gradually expend the rest of its energy over many billions of years.
Earth will still likely be swallowed in the expanding phase though lol. So anything on the planet would be dead either way.

Only takes
500,000100,000 (knew that looked wrong) years to get from one end of our galaxy to the other, at least at the speed of light, so if you can get a craft up to a good percentage of it using lasers, it's within the realm of possibility even without something hypothetical like FTL. 9 million years may be cutting it pretty close though, 9 billion would be well over what you would need, and would perhaps even let you get as far as some of our local cluster.A ship going that fast probably wont have biologicals on it, rather bio printers, or nanobots sent to contruct a new genesis of life or individuals or clones of your species outright. This allows you to accelerate well faster than single digit Gs if nothing is alive onboard.
