Experiments have clearly shown how Einstein's Special Theory of Relativity talks about time changes, length changes, and how we see things happen at the same time.
One well-known experiment used atomic clocks that were flown on fast jets. When these clocks came back, they showed less time had passed than clocks that stayed on the ground. This shows time dilation, which means time seems to slow down for things moving really fast.
Another example comes from fast-moving particles, like muons that are made from cosmic rays. These particles travel farther than we would normally expect when they are moving super fast. According to relativity, their size looks smaller when seen from a still place, which helps them reach the Earth before they change into something else.
A great example of simultaneity is a thought experiment where two people are in different places. If one person sees two lightning strikes happen at the same time, the other person who is moving may see one strike before the other. This shows that what seems to happen at the same time isn’t the same for everyone.
These interesting experiments help us understand the surprising ideas of relativity and change how we think about time and space!
