Question: Could Earth ever die? And if yes what would happen to us as humans?

Very good question! Well, everything has a beginning and an end, and the same is true for our planet. In about 6 billion years or so, our Sun is going to evolve to become a huge Red Giant star – hundreds of times the size it is now – which will engulf all of the inner planets in our Solar System, and destroy the orbits of those further away. No life would be able to survive, so we have to hope that the human race has advanced enough by then to have been able to build ships and go live elsewhere!

Here is a very dramatic video of this process:

Alternatively, long before this happens, Earth could be hit by a huge meteorite that could wipe out life as we know it (like we believed happened to the dinosaurs). If the impact doesn’t blow off a huge chunk of the planet to start with, the effects it would have on the atmosphere would ensure that a lot of living things on Earth wouldn’t survive. In this case, there’s probably not a lot we could do about it as humans, except hope it misses…
