Experimental Skills

Einstein showed that the speed of light is a universal constant. This means that it always travels at the same speed in a vacuum.

Use our simulator to investigate the effect of gravity on other worlds. Then use your measurements and a bit of maths to calculate the strength of gravity in each location across the Solar System!

You have likely heard about the Universe expanding. Or that redshift can tell us about the movements of galaxies. Both are difficult ideas to imagine and understand.
