if the sun was destroyed how long would it take for men to find an alternative source of energy?

Answer 1

If the sun was destroyed there wouldn't be any men left. Or women we would all die...

Answer 2

If the sun was destroyed we wouldn't have enough time to find an alternative source of energy. Not that anything would help. Without the sun the planet would die. The source of energy would have to be so many millions of miles away from the planet. It would also have to radiate enough heat & light for our survival.

Answer 3

Technically we don't rely on the Sun as an energy source as such. We rely on it for the growth of plants and animals for food.

I'd imagine that if the Sun suddenly blinked out, with no immediate effect on the Earth, firstly mankind would need to create shelter against the drop in temperature for himself and plants and animals. Without food and heat sources mankind would die, not so much energy. The Sun could be replaced in way of UV lights and such for plant photosynthesis.

Anyway, to answer the question, we already have alternative power sources. Although, fossil fuels will not last long, Nucleor fission reactors will probably become popular as a source of electricity.

Edit:

People, people, what are you going on about? Sure it'd get cold and plants couldn't do their thing, but not ALL life depends on the Sun to survive. And no life would die instantly upon being depraved of sunlight, we survive about 12 hours of it daily anyway.

Answer 4

We would have had to have found an alternative source long before the sun was destroyed. The planets in our solar system including earth would spin off all over the place if they didn't have the sun to orbit around. We'd probably drift into deep space for millions of years until we found a new sun to stabilise us.

I'm sure we'd have left this solar system and found that new star anyway long before our Sun was destroyed.

In the meantime (over the next 100 years) I think we'll get fusion to work properly so no worries.

Answer 5

If the sun was destroyed, there would be no point in finding an alternative source of energy because we would all suffocate. Plants need the sun to change CO2 into oxygen.

Answer 6

If the Sun was destroyed, we wouldn't need to find an alternative energy source as we would all be dead anyway, thereby negating the need. Even if one were found before the Sun was destroyed, we would still all be dead as soon as the Sun imploded to form a black hole, give or take the odd millisecond.

Answer 7

The sun is our main source of energy and one that our natural environment survives on. Without it, the natural environment would be destroyed. That means all plant life and water would disapear. We would freeze as the amount of energy needed to heat the earth to a liveable temperature is huge and requires anothe 'sun' to generate it. The earth itself is still cooling down from when it was formed so it has a vast amount of energy stored in its core, but extracting it and making it useful would be virtually impossible. Also, the energy wouldn't last long as comparable to the sun, there is only a tiny amount of it. To sum up, if the sun was destroyed, life as we know it would also be destroyed.

Answer 8

Well... they would either find a new source of energy for themselves and all other life on the planet WITHIN 8 MINUTES, or everything on the planet would die.

Eight minutes is the time it takes for the light from The Sun to reach Earth. So if The Sun blinked out of existance, we wouldn't notice it until 8 minutes later. But after that, the temperature would quickly drop to Absolute Zero (-273C, -459F), and everything would freeze to death.

Answer 9

well do we live underground???? recycling our own life support sytems?? burning coal I suppose is an option and mining for it??? Seeing that the place would be barren, frozen dark and cold - perhaps moving to another planet would be helpful, liek the ones in star trek where some planets have 2/3 suns and moons! Still, once the sun goes - so do we, the sea will freeze solid, then theres cannabilism, unless we'd got underground stocks like they did in the time of the cuban missile crisis in the states where they build bunker etc stored food - but these would have to be miles under the surface of the earth - maybe even close to the earth crust to keep warm
interesting question,

Answer 10

If the sun was destroyed, all natural plant life on the planet would die, and without plants to convert our expelled carbon dioxide to oxygen, we would run out of oxygen and everyone would die.

An alternate source of energy is the least of our problems. Hopefully we have achieve interstellar travel by then.

Answer 11

We'd all be deed, deed as a dodo!

Talking of alternative energy sources though .... with all this terrible rising sea water, it seems that it would be terribly sensible for us to start spending loads more time, effort and research on harnessing and using the sea for energy. Also if all our under ground water is running dry then why not also spend more time and money on converting sea water to drinkable or at least usable water and pipe it to residential areas? Also I reckon it is daft and frustrating that we spend millions and millions on space travel when there is a huge massive world here on earth, under the ocean that we haven't explored yet.
