The Sun Has Gone, Imploded And Disapeared, How Long Could We Survive?

[RATTER15]

Apart from being dark and cold, what other effects would we have to contend with?

[I_Hate_Infinity]

All the ideas I have for a post solar apocalypse have already been mentioned and described well. Food chain issues would be our main priority and lets not forget, the worlds supply of fresh water would go as no rain would deliver it to the land.

Now, might we also consider that if the Sun was removed from the solar system, the earth would fly off at about 30,000 mph and could impact the asteroid belt, at it's present orbit, in just 77.77r days. I doubt we'd survive that.

However, the orbit of the asteroid belt itself would disturbed to and affected more by Jupiter's influence, relative to their positions in space, which might fling asteroids towards us before we get to the congested area.

But assuming that enough asteroids are left in the path of Earth as it exits what was our solar system, in about 80 days we'd be like a target in a cosmic firing range.

IHI

so no time for a last beer or two before eer we gooooo.

[Bazile]

So a lot of important conditions have all come together to make the earth a habitable planet for humans and their ancestors

And all this happened by chance ?

[Old_Geezer]

Of course. It's a big universe, was inevitable it'd occur in many places by chance.

Bert, the surface of the Earth would become very cold indeed, despite the very hot core (5000 Celsius or thereabouts) and internal heating due to radioactive decay. The Earth's mantle and crust are very poor heat conductors. The Earth would radiate heat into space from its surface.

[Cathyhuns]

But isn't the atmosphere held in place by the earth spinning? And if we lost the sun, there would be nothing to keep the earth moving round the sun so it would head off at a tangent and eventually the earth would stop spinning and we'd lose the atmosphere. No idea how long that'd take but presumably it would be the end of life on earth.

[Bazile]

nay nay

intelligent design , dont you know

[jim360]

Who's to say that the conditions on Earth are the only ones capable of supporting life?

Anyway Bazile, IDT is completely unscientific and will stay that way.

[Teddio]

Cathy, the Earth's atmosphere is kept in place by Earth's gravity. If the Sun ceased to exist (hypothetically speaking) the Earth would cease to orbit the point where the Sun was and fly off (at 66 000 mph or so) in a straight line at a tangent.

Ahem... "The enormous fission reactor in the earth's core..." Looks like someone has been reading with the flashlight under the covers the writings (variously described as feverish ) of J. Michael Herndon, Rob de Meijer, Wim van Westrenen ... "Don't think so" says most scientists... But having never been there, I suppose it's open to discussion. Main problem is that only 2 or 3 anti-neutrinos (geo-neutrinos) have been detected over quite along period of investigation... far to few to involve any significant nuclear reaction...

[RATTER15]

Thank you Ed, at least someone understood what I was babbling on about, some of you people have no imaginations!!

Ok Ok, I didnt word the question very well!!

I was hoping for some replies on just how we could manage if we just lost heat and light, I cant be doing with all this technical science malarkey!!

[emmie]

but i thought that is what you meant. oh well, back to the drawing board.

[wildwood]

It all depends on how you describe "WE", is this as a Men species or planet's population? Most of the 3rd world populations will be gone in a few days. Nuclear power could keep the richer countries going for a few weeks but the lack of food would kill most of us off.

There are places on Earth where the planet's internal heat is accessible in hot pools and vents. This could sustain life for a few for maybe a few years.

[mibn2cweus]

But look on the bright side . . . no more worries about 'global warming'! :o)

[AB Editor]

So, assuming we're sticking to blighty, where should we build the bunker, and how deep?

[honeydip]

You can use artificial sunlight to grow plants. How do you think they grow weed farms?

[DangerUXD]

"The Sun Has Gone, Imploded And Dissapeared, How Long Could We Survive?" - well I know it's popular but I think we could revert to the daily Star if it becomes a survival issue.

[LazyGun]

@LoL at having to exist with just the Daily Star :)

If we are restricted to a bunker in blighty, I want one by the seaside. Somewhere in North Devon might be nice.

And I think we are all probably aware that plants can be grown under artificial light conditions, and hydroponics could be used as well - Good luck though growing enough food to sustain a population.......

[wildwood]

honeydip, where will you be getting the power from to energize the artificial light? Everything will be frozen solid so no fuel for generators. The planet's internal heat can be utilised for warmth and power but those places are few and far in between.

[Philosonic]

I can only imagine that without the Sun's presence to keep us in orbit The Earth would, along with the other planets around the Sun, drift off aimlessly and eventually crash into another celestial body or possibly go into orbit around another star. This would be quite an experience for us surviving on baked beans and methane heaters if we survived long enough!
