Invention that will change the world

Sustainable nuclear fusion and the further development of power cell technology
Pharmacogenetics (drug delivery dependant on genetic makeup) will revolutionise the pharmaceutical industry and human healthcare
Neural-computer interfaces - expect to be able to send a text message by thought control
Printable, flexable displays will turn the entire globe into a giant advertising board and super-size your home TV (which might be in 3D by then)

But I travel in time all the... er... time. The only problem is that it's only ever in one direction, and always at the same rate of 1 minute per minute.

Seriously, though, time and space are (or rather space-time is) relative. Time dilation (the measuring of different lengths of time by identical, accurate clocks) is a real phenomenon and its effect needs to be taken into account for GPS locators to function correctly. One can *never* say whether two events occurred objectively at the same time or not. It depends, quite literally, on your point of view.

See here for info: http://en.wikipedia.org/wiki/Time_dilation

And here for an experiment which "proved" the relativity of time and the effects of time dilation: http://en.wikipedia.org/wiki/Hafele-Keating_experiment

It's unlikely in the extreme that we'll ever be able to harness enough energy to permit large-scale "time travel" in any kind of useful manner.

Not really an invention though. It's a field of research and engineering. Although there will definitely be world changing inventions within that field.
