This simple simulator shows how space and time behave at relativistic velocities. It was developed as a pedagogical tool as part of a master's dissertation at the Federal University of Espírito Santo. Thus, it does not take into account the acceleration effects of the spacecraft. It was developed in a partnership between Prof Thiéberson Gomes (UFES), Prof Flávio Gimenes (UFES) and student Luiz Henrique Gobbi, with computational support Rodrigo Marques.
