Why does time seem to slow down when traveling at the speed of light?
This has been a controversial issue because no one experimented by traveling at the speed of light. It simply is not possible. So where do we come up with the idea that time dilates as we speed, and considerably, as we speed closer to the speed of light. It was detected when a clock that was observed on an Earth orbiting plane slowed by a billionth of a second compared to that on Earth. So, it is safe to say the clock slowed because it wasn't made for that radius of revolution. By that I mean a clock different from the clock that is invented to meet the earth's full spin on itself (24 hrs.) which adds up to weeks, months, and a full year when the earth completes one revolution around the Sun would read differently.
We can deduce from the above clock of our time measurement that all time measurements can be made according to the duration of a full cycle of something moving around another center of mass (Sun). We can also say with confidence that our universe is all about making cyclical motions around a certain frame of reference. We can fairly say there are planetary, solar, galactic, and universal reference frames where the clocks that measure their respective times work optimally. If that is the case, then our clock may not work the same way if we took it somewhere far into space, let's say Jupiter. It will try to count a year's time of revolution as on earth, which actually comes short of measuring Jupiter's year; its full revolution around the Sun. I believe it will move slowly to make up for the shortage. Does that mean on Jupiter we need a different type of clock made to measure the time it takes to complete a revolution around the Sun? I say yes because that way its days and years can be aligned accordingly.
So if we took earth's clock to Jupiter, what would change? Obviously, the radius from the Sun changed compared to that of Earth. That leads to the next question. If the radius (distance) from the sun changes at or close to the speed of light, what will happen to the Earth's clock we hypothetically travel with? Change in space means change in the radius(distance) from a certain reference point, around which every moment the clock has to adjust its complete cycle to make Earth's year. It can only accomplish this by moving extremely slow, to the extent that it seems it has stopped counting time.
If humans went with this clock, can we say they will be younger than if they stayed on Earth all that time? I can understand the clock's speed slowing, but not what it does to humans until it is practically proven?
One more point about the need for the term space time in physics is the alternative conclusion that can be made from the above analogy. It looks like time is a choice where it's required when the occupants of space (us) need to take track of time. Otherwise, I think things just happen no matter what time it is. If I can't schedule a meeting at a certain location without agreeing on the time to meet, it may not work here on earth, but I don't think the stars collide with a predetermined time and space of their own. In fact they don't even care. Things just happen in the outer space by objects in space simply obeying natural law, according to physics. Time applies for the occupants of objects the that have managed to interact gravitationally, thus forming the curvature of space. For any object that is wondering in an empty space without any gravitational influence, it’s no other choice but use the speed of light as a reference point to make sense of time. This situation is obviously an example of why time doesn’t exist in an absence of gravitational attraction between objects, as light isn’t affected by it.
My take on this subject:
The present and the future in our universe are repetitions of the past until a symmetry breaks. Symmetry is infinite and eternal. Where ever symmetry breaks locally, a short lived phenomenon occurs. Spiral galaxies, black holes, space time curve, gravitation, and lifeforms are some of the short lived phenomenon that exist until the eternal symmetry created after the BIG BANG wins its uniformity back. That is why there is a constant extinction of stars and formations of super novae, all happening to obey the command of a symmetric momentum in order to overcome(heal) the irregularity.
In conclusion, singularity is the only moment when the term "NOW" can be used in a perfect fit. Time after that belongs to the beholder, where my moment of now doesn't match your moment of now unless we're the same entity, revolving around the same frame of reference.
