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. ## Key features - Lorentz contraction visualization - Time dilation explanation - Relativistic speed calculations - Eiffel Tower example - Future travel simulation ## Recent user reviews (4 of 4) All indexed reviews: https://appshunter.io/ios/app/future-land/id340023788/reviews.md ### 1/5 — Unnütz..... *2012-10-27, version 1.1* ?????????????????? Aber wenigstens umsonst ### 5/5 — Koalabear94 *2010-03-18* Impressive but needs work, how about different buildings and objects for a start. ### 1/5 — Panda man87 *2010-02-22* What is this for ### 5/5 — Sehr gut. Sehr Sehr gut!!! *2009-11-21, version 0* Ich bin faszieniert. Einfach unbeschreiblich das App. Führ jeden Physiker empfehlenswert! ## Frequently asked questions about Future Land ### What is Future Land? Future Land is an educational application that demonstrates the principles of Lorentz contraction and time dilation, key concepts in Einstein's theory of special relativity. It visualizes how an object's length and the passage of time change when it approaches the speed of light. ### How does Future Land explain Lorentz contraction? Future Land uses the example of the Eiffel Tower to illustrate Lorentz contraction. It shows how the tower's length would appear to shrink from an observer's perspective as it accelerates to speeds close to the speed of light, based on the formula L = L1 * sqrt(1-(v/c)^2). ### Can Future Land simulate travel into the future? Yes, Future Land explains how traveling at very high speeds in a spacecraft can lead to 'traveling into the future.' The app details how time spent on board a fast-moving spacecraft would equate to a greater number of years passing on Earth. ### What devices does Future Land support? Future Land is supported on iPhone, iPad, and iPod devices. It is designed for Apple's mobile operating systems. ### What is the age rating for Future Land? Future Land has an age rating of 4+, making it suitable for a wide range of users, including younger learners interested in science concepts. ### How often is Future Land updated? The latest version of Future Land is 1.4, and it was last updated on July 19, 2025. This indicates recent development and potential for ongoing support. ### What is the price of Future Land? Future Land is a paid application and costs $0.99. This one-time purchase grants access to its educational content. ### Does Future Land have ads? No, Future Land does not contain advertisements. As a paid application, it offers an ad-free experience for users. ## Version history (last 5 releases) ### 1.4 — 2025-07-19 Compatibility with newer devices ### 1.3 — 2022-02-23 Compatibility with iOS 15 ### 1.20 — 2019-01-15 Compatibility with iOS 12 ### 1.1 — 2010-09-21 iPhone 4 and iPad compatibility ### 1.0 — 2009-11-20 No release notes. ## More apps by Pietro Massimino - [Total Solar Eclipses](https://appshunter.io/ios/app/total-solar-eclipses/id332379841) - [Depth](https://appshunter.io/ios/app/depth/id336473396) - [iCucu](https://appshunter.io/ios/app/icucu/id415488842) - [LuciApp](https://appshunter.io/ios/app/luciapp/id1230400886) - [Bit Clock 1010](https://appshunter.io/ios/app/bit-clock-1010/id6743941936) All apps by Pietro Massimino: https://appshunter.io/developer/332379844 ## Related topics [futureland](https://appshunter.io/ios/topics/futureland) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
