About

Relativistic

Explore the effects of relativity by adjusting the speed of light and observing real-time changes. Simulate scenarios like time dilation and gravitational blueshift by placing observers and celestial objects on a map. This app offers an intuitive method for understanding Einstein's theory.

Highlights
  • Adjustable speed of light
  • Real-time relativity effects
  • Observer placement and time dilation
  • Black hole simulation
  • Gravitational blueshift visualization
  • Intuitive learning tool

Experience the world at the speed of light. Relativistic lets you set the speed of light to walking pace and then walk around your neighborhood and see the effects of relativity in real time. Place observers on a map and watch their time slow down and speed up relative to you as you move. Place a black hole at the end of your road and watch outside observers glow blue as you walk towards its singularity. Relativistic provides an intuitive way to learn about and teach the details of Einstein's theory of relativity.

About

Make Chirps

Features
Read full description

This educational app displays gravitational wave chirps created by mergers of massive black holes in several different ways, giving users an intuitive understanding of these exotic disturbances of space-time itself produced by cataclysmic events in distant galaxies. FEATURES: • Simulation: Experience the intricate behavior of gravitational waves through physics simulation of inspiralling black holes that merge to form a final black hole which then “shakes off” its excess energy. • Visualizations: See the essence of gravitational waves via waveform plots, frequency evolutions, and spectrograms, to understand the patterns and how they depend on black hole masses. • Auditory Experience: Listen closely as you hear the evolution of gravitational waves, detecting the characteristic increase in time in strength and frequency. Try varying masses to see how pitch is affected. • Dynamic Animations: Witness the captivating dance of black holes in collision animations. Explore the propagation of these waves through space-time with mesmerizing spiral animations. • Educational Insights: Gain a comprehensive understanding of gravitational waves and the pioneering work of LIGO through informative text pages, enhancing your knowledge of these cosmic phenomena. COMPATIBILITY Compatible with iPhone and iPad, iOS 16 or later. ACKNOWLEDGEMENT Supported by the National Science Foundation with grant PHY-2110181.
