There are two ways that one can legitimately travel into the future.

Method 1 – Moving Objects Age Slower

Thanks to Einstein’s work on the nature of time, there is no ‘absolute time’.  We all keep our own clock and our own time – and everyone’s clock (tick rate) depends on their velocity. The faster one moves, the slower their clock ticks.

So – if one were to move very close to the speed of light and return back to earth after a 2 minute journey, folks on earth would have aged 50 years…In a sense, we would find ourselves in Earth’s future!

Method 2 – Intense Gravitational Fields Slow Down Aging

Clocks at the bottom of a skyscraper run slower than at the top. The greater the gravitational field, the slower clocks run.

So, if we were to stay inside a REALLY powerful gravitational field, we would experience time slowing down.  Making a trip to the boundary of a black hole and staying there, would provide us again with a slower clock, so that when we returned to earth, we would find ourselves in the future!

What about time travel, not into the future, but into the past?

While the laws of physics allow it – and while a particular solution to Einstein’s equations (Wormhole solution) do exactly that (join two different spacetimes through a tunnel), the actual possibility of doing something like this remains low.  A good question to ask is – If this is possible, why haven’t we seen a single visitor from the future?

Summary

This was just a fun recap of what is currently possible – both in the world of physics as well as the world of engineering.  Time travel to the future doesn’t seem to be far fetched – although travel to the past seems to be a little more elusive.
