Speed of light

[cwong]

Im new to this, it's interesting, but when i tried the light pulse thing, how do you actually tell how long it takes for the light to reach another body? It says 1.2 seconds to reach the moon, but i can't find a clock or something that says that...
is there actually something that will tell you the time it takes for the light pulse to reach someone or do i have to manually use a stopwatch?

You can use the time step menu:

You can set 1 sec = [time], and it'll fix the accuracy of the simulation so that each second in the program is one real second.

(One time step is the amount of time (in the program) between each time it calculates the position of all the objects in the simulation, so the more you increase it, the more inaccurate it gets.)

In this simulation, each time one second passes in the real world, 8.11 hours pass in the simulation.

A stopwatch is an interesting idea.

Thanks Bla for the screenshot. Very helpful.
