Simultaneity
Simultaneity
This expository applet works through two examples of simultaneous events occurring in different reference frames. Users will see worked examples using the above spacetime diagrams in order to understand that the velocity of a reference frame affects simultaneity.
About BeeGames social
Playground and Play together are the BeeGames social layer — so you're never just playing alone.
What is a Playground?
Your Playground is your own personal game homepage. Pin the games you love, give it a name and a short bio, then make it public to share your personal arcade with anyone.
How do I use my Playground?
On any game page, tap “Playground” to pin that game. Head to My Playground to edit its name, bio and layout, then share your public link with friends.
What is Play together?
Play together lets you co-play the same game with friends in real time. Open a game room and everyone can play side by side while chatting in the room — like crowding around one screen, online.
How do I play with friends?
Tap “Play together” on a game page, pick a public room or a private one with a password, then share the room link with friends. You can also browse and join open rooms from the Lobby.
