About

Future Land

Explore the fascinating concepts of time dilation and length contraction as objects approach the speed of light. This educational tool visualizes how time and distance are perceived differently at relativistic speeds, demonstrating real-world physics principles.

Highlights
  • Lorentz contraction visualization
  • Time dilation explanation
  • Relativistic speed calculations
  • Eiffel Tower example
  • Future travel simulation

Lorentz contraction The lenght of an object moving at speeds approaching the speed of light, with respect to an observer at rest, will contract along the direction of motion by the factor L = L1 * sqrt(1-(v/c)^2) where L is the length observed by the observer in state of rest, L1 is the length measured when the object is motionless, 'v' is the velocity of the object and 'c' is the speed of light (about 300000 km/sec), In our case the Eiffel Tower (about 320 meters) when it approachs the speed of light its lenght will shrink as the screen image. The program will also display the correct data. Time in the moving system will be observed by a stationary observer to be running slower. In other words if the Eiffeil tower would travel during one year (tower time) at 95% of the speed of light, the elapsed time on the Earth will be equal to 3.2 years and the tower lenght will be about 100 meters. Travel into the future. It is possible "to travel into the future" by using a very speed spacecraft. Depending on the acceleration of the spacecraft (in our case from 1 to 5 G) and the time spent on board, on the Earth will spend a greater number of years.

Verdict

The call

The clearest difference is price: TED at Free against Future Land's $0.99. TED also leads on rating (2.2 vs 1.0) and update cadence (weekly vs every 40 months). Future Land's advantage is review sentiment (50% vs 14%) and iOS requirement (11.0 vs 17.0). On ads, in-app purchases and device support there is nothing between them.

TED is free to download; Future Land costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

TED holds the better App Store score, 2.2 against 1.0. That said, the two scores are not equally well evidenced: TED has 11 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of Future Land's written reviews are positive against 14% of TED's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Future Land ships an update every 40 months, TED weekly. The most recent releases landed on November 1, 2026 and November 7, 2026 respectively.
