Relatively Special Deliveries - Delivering the packages of today - tomorrow!

Thanks to Einstein’s Special Relativity, time slows down for a traveller moving at near light speed. We make use of this property of space-time, plus our expendable employees, to run your future errands!

That’s right, for only a handful of SpaceBucks, we will plunge into the far-flung future to deliver things on your behalf. Worried about forgetting your anniversary in 10 years? We’re on it! Want to send a birthday present to your great-great-great-grand daughter? Look no further!

With Relatively Special Deliveries, the future is now!

*All trips are one-way, travelling back in time is not possible with our current understanding of physics. RSD is not responsible for any loss of goods or personnel due to cataclysmic future events.*

------------------------------------

This game uses real physics to calculate the difference in time experienced by a stationary person and a person moving at near light speeds. This is called Time Dilation and was predicted by Einstein's Special Relativity.

Time dilation is calculated using the following:

delta_t = delta_tau/(sqrt(1-(v^2/c^2)))

where delta_t is the time on Earth, delta_tau is the time on the rocket, v is the speed of the rocket and c is the speed of light in a vaccuum.

As the speed of the rocket approaches the speed of light, time slows down for them exponentially, allowing them to travel far into the future.
