realUniverse 2.5

We can think of our lives, through our planet, our solar system, and the universe by seeing the number of movement of these as well as light travels.
Lorentz transformation is also visualized. A clock on a high speed rocket is shown, comparing a conventional clock on the earth. The rocket speed can be changed from 0.00 % to 99.999% of the light speed. The faster the rocket, the slower the clock on it by observers on the earth.
