Here’s an amazing apparant proof that time dilation is real, that time is relative, that it stretches and shrinks relative to others depending on your relative velocity. If this were not true, we would not be able to detect subatomic particles at the surface of the earth known as muons (similar to electrons, but larger) which are created in the atmosphere by cosmic ray impacts. If you have time, watch this video and think about the time you have, for a moment.
Who undertands how strange elastic time truly is? The consequences are astounding. The earth is, in fact, flattened from the perspective of a muon.
