The future gadget is a full-fledged time machine, albeit it is still incomplete and, as a result, is only capable of allowing the user to travel backwards in time, as opposed to the time machine developed by SERN, which enabled time travel in both directions. There is one exception to this, however. In the Beta worldline, the time machine is able to travel both forwards and backwards in time, but requires a large quantity of fuel in order to travel.
