I’m hoping this won’t happen in our lifetime, but if it does, lets hope it happens very quickly so we don’t know.

It’ll vanish with a quiet pop, like the sound of a cork, and a little puff of steam that smells of cinnamon.

Hopefully it will be beautiful and colourful, and we will watch it happening from a different planet which we won’t be killing at the same rate like we did with Earth!

I’m hoping that it doesn’t happen soon and that it’s something that we haven’t caused ourselves.

I guess if we get to actually see the end of the world it’s because we are safely away from it, and then I hope it is at least a beautiful thing to watch while eating popcorn!

We will all scream and run around waving our arms in the air wondering how we can protect the cats.

I have no idea what will happen… but I imagine the world will be sucked up…zoooomp…into a super massive black hole and we will not feel a thing!

The Earth is thought to have another 4 – 5 billion years before it ends. After this time, the sun will become what is known as a ‘red giant’ and consume the Earth. For the past 4 billion years, the sun has been in a stable phase of its life cycle. During this phase, hydrogen gas in the suns core is converted into helium – a process that produces lots of energy. Eventually, all of the hydrogen gas in the suns core will be used up. All of the helium that has built up over the billions of years will become unstable and collapse, causing the core to heat up and become denser. These events will trigger the beginning of the red giant phase. Luckily, life on earth should have ended way before the world ends. As the sun increases in size and gets brighter, oceans will boil and ice caps will melt. Eventually, all water vapour on Earth will be lost, meaning that life on Earth can no longer exist.

In terms of the physical world, I think the sun will expand due to its turning into a ‘red giant’. Which will mean that the Earth will slowly heat up, causing it to become unable to support life.
However in terms of human civilization, I hope that before this time we may have found a way to travel to other planets and to create new worlds there, meaning that the ‘human world’ can live on, just on another planet. Unfortunately I know I wont be around to see that, but hopefully all of you new scientists will help to make that possibility real.

I think that if we know the world is going to end, then at least some people will be sent far enough away that humans will survive. BUT I don’t necessarily think this is a good thing. We have already messed up planet earth, why should we get to mess up somewhere else too? Unless we become far more responsible as a species in the future, I think we should be the captains that go down with out ‘ship’.

There are infinite possibilities of how this might happen, but if it takes long enough for us to know about it, I guarantee other animals will sense it coming before we do – we have in many ways become so disconnected from the natural world that we fail to see what is right in front of us. On the plus side we have developed so much as a species, that we may figure out just in time how to save our planet (or ourselves). However it happens, I hope it’s painless and mesmerizingly beautiful.
