Two real quick thoughts:

1. Human vision with no sun or moon or artificial light isn't a remote concept; I've actually experienced it myself in the Canyonlands of Utah. One can't see very well with starlight, and there's not enough light to perceive color, but it's still strong enough to avoid walking into things.

2. One wonders how developed life is/was/could be on some of our outer planets' moons like Europa; presumably they have similar internal heat sources.

Except Claude of course!

I doubt stars reflect any noticable light or heat from our sun. Even if they did, they are multiple light years away, so it would take quite a while for the sun's light to travel to the stars and back again. However, the moon does reflect light from our sun, so nights would be pitch dark.

Earth would freeze in a short time. It would also have none of the sun's gravity to hold it in orbit, so it and all the other planets, moons, asteroids, comets, etc, would "fly" around. Since the solar system would be without a sun, there would be no SOLAR system.

Gravity is something I've always found interesting. For something that effects all mass in the universe and something we have known about and studied for a long time, we still don't fully understand it.
Interesting article here about gravity. Where Does Gravity Come From?

Yep, would suck to be them.

All life on the surface would die within a few weeks, there would be no adaptation. Any humans holed up underground may survive for a time given that they have heat and light and air and food and water. That will be very brief.

Possibly underneath the miles of ice covering the earth there will be some liquid water and it will be warmed by the earths internal heat deep down, some crude microbial life may survive and flourish. That's all!

Given the zillion to one chance that the earth does eventually get caught up in a stars gravity and go in to orbit at the right distance and the star is the right size and type their is a vague possibility it would warm the Earth and life could start up.

I suspect the moon that would still be orbiting the earth would have long de-stabilised it's orbit long before then and crashed into the earth. The sun does exert some gravitational pull on the moon as well and the effect of it vanishing would be a factor.

Gee, I wish some of you guys sometimes watched science documentaries. Science is such a wonderful thing. There are at least 4 different lifeforms on our earth alone. Only plants and oxygen based lifeforms will die without sun.
HOw abuot the Black Smokers? The life down there is totally independant of sun. How come you never heard of them?

They will die if the ocean freeses completely, but thet cant happen. They live as long as there is geothermal energy.

Arrr, no, another science doc, showed that after the red giant phase, our sun would end up being a brown dwarf, (if l remember correctly) a dim and much smaller version of our current sun, then eventually it would emit no light, but still be dense enough to keep our solar systems planets in orbit.

But if the sun vanished, then our planets would be all over the place, some would fling off in all directions.

Mercery being the fastest, but some might eventually get could in Jupiters or Saturns orbits, And could end up being a rouge solar system, with no sun, until it hits a more conventional one!

Not at all. In fact, we could use another intelligent voice. Do you think we all agree with each other? Almost never.

But....acting like a jerk will get you ignored. (the reason I haven't addressed you yet), and eventually banned. So, just keep it friendly (which does not mean agreeing) and you'll find yourself in a rewarding discussion.

Let's add something here. The Earths crust is an excellent insulator of heat. That's why it's cool up here, and we have a liquid molten mantle. Water is a pretty poor insulator of heat. It's why we feel cold in water that is room temperature.

We have black smokers. But we also don't have a surface temperature of near absolute zero. If we did, I think the black smokers would heat a smaller amount of water to keep it from freezing.

Remember the Snowball Earth? And that was when we still had an active Sun heating our planet. Then, the surface was maybe 50 below zero......but without a Sun? How would a surface at 300-400 below zero affect the smokers? And on Snowball Earth, nearly all life was extinguished (according to fossil records).

Anyway, this is all just a thought experiment based on an impossible scenario.

Hmmm, better watch my Stephen Hawking video again!

I know that the video doesn't address the unreliability issue, but tech, it does show, that achieving a worthwile percentage of light speed, to get there a lot quicker than 70 years, is possible.

It all boils down to time and resources, if some need to be sacrificed, then they do.

Maybe send a fleet on first, (the poor) then a second round of robotic ones, to clean up the mess, then send the rest.


UFO propolsion, hmmm, talk to the US gov, they already have light speed propulsion, but only use it for short bursts, since long distances, have collision issues!

Oh yes. They were called to get their view on the topic. They agree. If the sun were to just disappear, it would get extremely cold. They were not as worried about gravity as those with the idea of a spherical earth, however.

Yes, an update, from the best computer model, in Europe, we will have a good billion years before the sun adversary affects us!

This is from a science mag, l looked at today!

So nothing to worry about!

^ Post of the day.^

See people, it doesn't matter. The sun would go out and hey presto we'd build a spaceship, pack the worlds population in it and just bugger off to another galaxy where we'd just naturally breathe and set up a few Walmarts.

Piece of piss. Anyone could do it.

Claude would be going door to door selling martian vacuum cleaners and Shane would be selling fluffy bunny suits and talking in a cockney accent to take the piss out of me. I'd open the first of many of the "Richard and Dan" bars that would be on every street.

I wish the dam thing would just go out so we could get on with it.

And impossible. Sleep well.


Well......truth be told, I didn't watch the video when you first posted it. I didn't know it was the same video.

Forgive me, my young apprentice.
