The future is the time that comes after now.

Because of time and physics, the future must arrive. Some things are permanent, which means they last forever. Other things are temporary and will eventually end.

In physics, time is the fourth dimension. Scientists say spacetime is like a stretchy fabric. This fabric can bend because of gravity. Some thinkers believe in presentism. This is the idea that only the present is real. Others believe in eternalism. This is the idea that the past and future are also real.

Special relativity is a theory about how time works. It shows that time can change for different people. If you travel at very high speeds, time moves slower for you. You could even travel into the future this way. Some scientists think a wormhole might let people travel through time. This would need the power of a whole star!

People also think about the future in many ways. Some people are optimists. They see the world as a positive place. Others are pessimists. They expect bad things to happen.
