Scientists say sun is dying star.if so how can we survive later?How can we get near another star?

Question

HI THIS IS TORI SABE

Answer 1

u need to understand 1 thing. it is almost impossible to overtake nature. One instant is, teleportation. We know many ways to accelerate protons & electrons, but we are surely in short of techniques to accelerate a neutron. Thats what is nature. By far only hydrogen atom (or its group) has been telepored successfully bcos hydrogen dosen't have a neutron. So if man learns to travel at the speed of light and to accelerate neutron, yes tori ur question will be looking interesing. But for the moment we have many a questions to answer.


teleportation: travel between any two points in space (say A and B) without moving through space. Yeah it looks like impossible but it has been made possible by the very same scientists...

Hope this answer seems interesting and gives u some sort of info relevant to ur question.

Answer 2

Hello!

First of all, as soon as any star is "born" it is "dying". We are just fortunate to live near a star that "only" uses up four billion kilograms of mass per second! With the sun being a medium sized, middle of the road star, this means it will keep shining for another 5 billion years, happily burning hydrogen into helium. However, as soon as most of the hydrogen is gone, we're going to have some serious problems here on Earth!! The sun will bulge up to become a red giant.....well...this isn't going to be OUR problem, humans will probably be long gone before that.

The chances of numerous other things happening first are far more possible. Remember, the Earth has gone through many stages in the past!! Dinosaurs were around just 200 million years ago!! Imagine how much plant and animal life has changed since then alone. This is just a fraction of 5 billion years!!! Every 26,000 years, the Earth precesses and it is thought to be the cause of the Ice Age. So, we're bound to have another one of those "soon" too. And then the all destroying asteroid. You can track those here: http://neo.jpl.nasa.gov/ca/ So far, nothing is getting too close, but there have been some scares when someone did their math wrong in the last couple of decades!

And finally, leaving Earth. Can we do it? Maybe....but there are dangers out there...astronauts can only stay in space because they are close to the Earth's magnetic belts and it shields the astronauts from radiation, anyone leaving those magnetic belts won't have that same protection. This could cause a high risk of cancer for humans.

What about traveling at the speed of light? Well, so far....as far as we know, nothing with mass can travel the speed of light. If we COULD and knew where a planet was that we could travel to, it wouldn't take that long. Once you are at 99.9 % the speed of light, time slows down, making a 10 ly journey seem like just weeks. At least according to Einstein.

If we have to travel to another star with our current technology, we'd never make it. It would be thousands and thousands of years, maybe more before we made it. That is, if we didn't die of radiation poisoning first.

Answer 3

Not to worry. The sun will be around for another 5 billion or so years. It will pretty much coincide with the collision of our galaxy with Andromeda galaxy. Hopefully with the recent acceleration of technology, we will have either, conquered light speed, or possibly teleportation, maybe even warping space and time. In the near future we might build a large, self sustaining, rotating space station. The rotation would create an artificial gravity, It would have to be large enough to sustain 10 to 14 thousand people, with room for 100 to 150 thousand more. Once built, it would have to have trees, and plants for help or total oxygenation. there would have to be millions and millions of gallons of water, as it may not ,even on this scale be self regenerating, as it is here on earth. After all details are finally attended to, this Craft, could be propelled toward another star. At sub-light speed, humans could survive for the many generations it would take to get there.

Answer 4

Another responder suggests the sun will die out in 20,000 years. Yet another indicates 4-5 billion years. The second responder is much more accurate. The sun will begin expanding in 4-5 billion years.

It probably will not expand enough to engulf the earth, though kiss Mercury and Venus goodbye.

At the rate our technology is growing, we will probably be able to swap suns within another hundred thousand years. I recommend a smaller red dwarf, which won't be as dangerous and will last much, much longer.

Answer 5

In the next 5 billion years or so the sun will expand and consume the inner planets,including the earth.
Any other star around us should have suffered the same fate.
Things would be pretty hot no matter where you went.
Better get started on a solution.

Answer 6

Life on earth will face many more destructive calamities before the end of Sun. And if human race still manages to survive for further 4 or 5 billion years, it will not be able to survive after the end of Sun for sure.

Answer 7

The sun will still be around, essentially unchanged, for billions of years - i.e. for longer than there has been life on this planet.

Will the sun eventually die? Of course. However, trying to solve that "problem" today is like asking Neanderthals to figure out how to best launch a rocket to the moon. Let our descendants millions of generations from now worry about this "problem" - assuming the human race is still around, they'll manage it far better than we ever could.

Answer 8

we won't be able to survive once the sun dies (In about 4-5 billion years). With our current technology it would take about 2000 years to get to the nearest star, and who knows if there is a habitable planet there. Even if we could go the speed of light (which we can't) it would take 4 years to get there. So unless we create a hypothetical rip in space time to create a wormhole then our chances of survival aren't looking too good.

Answer 9

well, first of all. No one is going to be around to witness the Sun running out of fuel. We will most likely be hit by an asteroid. It will only require a asteroid to be 1 mile in diameter to turn earth into a scorching oven. If anyone does manage to survive that, they will then face the challenges of living in total darkness due to the dust that will engulf earth of a few years. Then if ALL of that doesn't happen...i'm sure we will have destroy each other with our own nukes.

Answer 10

Yes the sun is currently in middle age, in about 5 billion years it will use up it's fuel and start expanding into a red Giant and swallow Mercury, Venus and Earth. Then it will shrink into a white dwarf.
