The Relativity Simulator is a mind-bending text-based simulation that explores the intricate and often counterintuitive world of Einstein’s theories of special and general relativity. Step into a realm where time dilates, lengths contract, and gravity warps the very fabric of spacetime. Navigate near-light-speed voyages, witness the slowing of clocks, observe the bending of starlight, and experience the gravitational redshift of distant objects. This simulator offers a unique, conceptual journey through the universe’s most profound physical principles, revealing the strange and beautiful consequences of motion and gravity on the cosmic stage.
