The weather is getting hotter and hotter. Is the earth going to explode?

1 It will explode when a planet hits the earth in the future.

2. Stars and planets have their own lifetimes, when explosions will occur. The life of the earth is only 4.6 billion years, and there will definitely be an explosion after several billion years, so you won't have a chance to see it.

Your idea is right, but there is no sign of explosion on the earth at present.
