By the time our sun turns into a Supernova and blows up will we be long gone in other planets?

Question

afterall we are millions of years from that..... i think with our intelligence we will build artifical sunlight and make our own atmospere not dependent on stars or................... we will warp ahead to another galaxy that has a sun

Answer 1

Our sun has been in our solar system 5 billion years and will be another 5 billion years. It will get bigger and bigger during those 5 billion years. Then it swallow Mercury, then Venus, by the time it swallows earth it will become a big supernova. then blow up to become a little planet like Earth. After that slowly it will disappear into gas and dust.
If we want to survive then we have to go to other stars. The nearest star is 4.3 light year away. If our technology is very good then we will go there.
When I say swallow I mean when the sun gets bigger the planets get into the sun.

Answer 2

There are currently 6 billion people on Earth, by the time the Sun explodes, there will be uncountable numbers of humans. To warp ahead to another galaxy would call for all the raw materials in the solar system - and then some.

Regarding creating artificial sunshine, I can't imagine coming up with anything as powerful as the sun - and if the sun goes super nova, it will expand past the earth's orbit, incinerating the earth and ruling out your artificial sunshine.

Answer 3

Probably not. Also the sun is not massive enough to go supernova it will get freakin huge for a couple million years (red giant stage) then puff off it's outer atmosphere leaving the core to fad away. So basically if we are around buy then we get fried. So the earth will cook then freeze and that is all if the suns size doesnt engulf the planet.

Answer 4

The sun won't go supernova. It's not massive enough to do that at the end of its life. It will become a red giant then a white dwarf.

It will be a few billion years in the future when the sun dies. Hopefully humanity would have figured out interstellar travel and colonized other star systems by then.

Answer 5

We won't ever have to worry about that.

By that time, the zerg swarm will have already invaded and laid waste to our world. Protoss war ships will appear from warp space and left with no choice will burn our planet to a cinder in order to stop the spreading and infestation.

That, or mankind will have evolved into something totally beyond what we are now (it will happen in about 6 billion years to the sun by the way, not millions), none of our artifacts will have survived, and we will be spread througout this galaxy and others.

It's fascinating to consider.

Answer 6

Let me be the critic:

1. Our sun is too small to go supernova, it will simply continue to use up its fuel and grow to a red giant as it does. Then it will collapse and become a white dwarf.

2. Intelligence has nothing to do with it, I think we're not wise enough to move at that time. Look at all the people who live in disaster zones, like the gulf coast, California, etc.

3. IF we did move on we wouldn't need to go to another galaxy.

Besides when the aliens from Betelgeuse land they will turn us into farm animals and make us all into burgers. ;)

Answer 7

There are 2 styles of supernova. Our solar gained't grow to be both of them. the first the the outcome of a extreme mass (better than 8 cases the mass of our solar) celeb. on the suitable of its existence the celeb can't help itself anymore, it colapses on itself, rebounds and blows off all of it truly is outer layers in an rather lively adventure referred to as a supernova. OUr solar isn't huge for this to happen, instead it is going to run out of gas and gently "puff-off" it truly is outer layers leaving a warm, white dwarf in the back of. there is yet another form of supernova. If a white dwarf has a celeb going round it numerous the gas from this better half celeb can spill onto the white dwarf, slowing increading its mass. If sufficient mass is transfered to the white dwarf it is going to fall down, flash-fusion all of it truly is totally last carbon into iron and blow itself aside dramatically. because the solar does no longer have a better half celeb to thieve mass from as quickly because it is going to grow to be a white dwarf it gained't grow to be this way of supernova both.

Answer 8

Sol is a yellow dwarf star. Yellow dwarfs eventually bloat, blow off their outer layers, and spend the rest of their days as a cooling white dwarf starts. It will happen in a frew billion years - mark your calendar.

Nobody on Earth is going anywhere outside the solar system unless Special Relativity is finessed. There is no evidence and no reasonable speculation that it can be done. Think of something new, clever, and doable.

Answer 9

First, our sun cannot turn into a supernova (he is not dense enough for this), second, I am not sure our specie will survived long enough to colonized any world at all!! But if you want a dream, then, I think Aliens will visit us and help us to save our planet!!

Answer 10

we'll be extinct by then... in 20 - 30 years we'll be warring over the price of oil or lack of it. this will lead to mass starvation, nuclear fall out and eventually the demise of the human race.

maybe a cynical view but if we don't sort out an alternative fuel source by then the future is extremely bleak… think about it!
