TIME AS A GIFT
2024 - CHRISTMAS SUNDIAL
Time Dilation
YES, THIS NEXT PART IS GEEKY. But hang in there, It might be worth it...
Time dilation is the slowing of time as perceived by one observer compared with another, depending on their relative motion or positions in a gravitational field. It’s a consequence of Einsteinian relativity, in which time is not as absolute as it might appear; the rate at which it passes is different for observers in different frames of reference.
Relative motion of objects
As one of his many theories, Galileo suggested that one cannot tell if they are moving if it is at a constant rate. That’s why we don’t feel dizzy because the Earth is constantly spinning around the sun. This is the core idea behind relativity.
Theory of Special Relativity
Special Relativity, Einstein took relativity into the context of the speed of light. Essentially, speed affects mass, time and space; Thus, he created the famous equation: E = mc^2.
General Relativity
General Relativity, is an extension of special relativity to include gravity. Gravity is the curvature and warping of spacetime, caused by massive bodies causing time dilation. Thus, the closer you are to a large mass the slower time goes
Relevance of Time Dilation 'AKA Proof'
Time dilation is particularly relevant to spacecrafts because of their high speeds and changing gravitational fields. For example, the Voyager 1 is approximately 1.2 seconds younger than it would be if it remained on earth. Additionally, GPS satellites have to account for 38 microseconds (millionths of a second) per day of time dilation (45 microseconds from gravitational time dilation plus 7 microseconds from the speed-related effect totaling 53 ms)
Conclusion
Time dilation is experienced by everything in the universe at a subatomic level. In fact, your head is actually older than your feet. While time may seem fixed or absolute to us experiencing it, time is actually relative. (Example: Some heads are younger than other. Especial the short people we know.) :)
Time Fun Facts...
65 million Years Ago
65 million Years Ago
65 million Years Ago
When the dinosaurs were alive, there were 370 days in a year. The Earth's spin is getting slower because the moon's gravity is acting as a drag, so days are getting longer, by about 1.7 milliseconds per century.

The smallest standard scientific measure of time is the "Planck time". It takes you about five hundred and fifty thousand trillion trillion trillion Planck times to blink once, quickly.
Seeing into the Past
65 million Years Ago
Seeing into the Past
Because light takes time to reach us, everything we see is in the past. The sun you can see out of the window is 8 minutes and 20 seconds old. The light from our nearest star, Proxima Centauri, is 4 years old.

Seeing into the Past
The universe is 13.8 billion years old, give or take. If we compressed that into a year – with the Big Bang happening at 00:00:01 on 1 January – then the dinosaurs would be wiped out on December 29th, and modern humans would appear at 11:54pm. Christopher Columbus would sail across the Atlantic one second before midnight.

Time and Your Age
New experiences really do seem to be longer in the memory than familiar ones. It's called the "oddball effect", and it seems to be why time feels like it's going faster as you get older – because more stuff is familiar to you.
