What happens to time at the speed of light? If a person is traveling at a high speed do they age faster or slower relative to a stationary person? Is it theoretically possible to stop time?
No, that's right. From the neutrino's perspective it takes a very small amount of time to traverse what we would measure as 1 AU. (How small exactly the amount of time is, of course, depends on how fast it's traveling)LawrenceM said:Okay, so if I ask the same question but change "photon" to "neutrino" and "c" to "nearly c" - The clock would read something arbitrarily close to zero.
So from the neutrino's perspective, it takes – arbitrarily – almost no time to traverse 1 AU, while we would time that journey as something slightly over 8 minutes. Or am I still off in my own universe?

The question is about as meaningless as what's north of the north pole.
diazona said:Well, I can say this: if you see a person traveling past you at a high speed (relative to yourself, of course), then you will observe them aging slower than you are. But that person will see you traveling past them at a high speed, and therefore they will see you aging slower than they are. It sounds strange but this is actually possible (and real) because there is no "absolute time" to fix one particular rate of aging that all others must be measured against.
As for stopping time... consider that person from the last paragraph. The closer they go to the speed of light, the slower you see them aging relative to you, so you would think that if they ever actually reached the speed of light, you would see them not aging at all. But it's impossible to actually reach the speed of light, so it's kind of a philosophical question, not a physical one.
That is a violation of special relativity and so impossible. As the object spins faster and faster, it takes more and more power to continue the acceleration.PaulRacer said:Heres what I am getting at, we are basing all of our knowledge on our size. If you had a motor in space spinning anything with a circumference of 186,000 miles at 60 rpm there is the speed of light.
I don't understand any of that - it sounds like gibberish.Why wouldn't the Earth be twisted inside due to time infraction in the core vs. the surface? If there is a time infraction twist does it pull inward or push outward. It, to me would look much like the milky way if this were true. Is there such a thing as time related friction? Sorry for the disjointed thought, I just spent all day grinding steel in a factory and the beer went down easy.
LawrenceM said:i think he's asking if time moves slower on Earth's surface than in the core due to the difference in rotational velocity. If so, what would be the implications?
PaulRacer said:Exactly, if you stretch a rubber band, there is energy expended and that energy becomes heat. So does the time differential stretch of the Earth mass create heat consequentially slowing the rotation or some other effect?
LawrenceM said:I wish I understood enough to give you any type of answer. I'm still not sure if anyone has confirmed whether time differential on a given object exists. Even if it does, I'm not sure if anyone has confirmed that a time differential within an object can cause mass to stretch or create any type of energy whatsoever.
PaulRacer said:What about in the case of a black hole where the diameter is so small that the time differential is very minute.
PaulRacer said:Does the twist unwind
PaulRacer said:releasing all of it's energy
PaulRacer said:or would this require a reversal of time?
PaulRacer said:Do you think this makes some sense though or am I just babbling?
PaulRacer said:Time differential because core velocities and surface velocities on Earth vary by up to 1000 miles an hour, the faster you travel, the more time slows. Over time this slight difference in time should add up and cause a twist due to the surface time rotation trying to catch up with the core time rotation. If there is a "twist", I would think that it would have a lot of stored energy. If time stopped would this twist still remain or would it unwind itself? Sorry my explanations are not very good.

Exactly, if you stretch a rubber band, there is energy expended and that energy becomes heat.
Naty1 said:from v = wr (w being angular velocity) someone at the surface moves faster than someone in a mine 2,000 feet underground.
Time does slow with increasing gravitational potential...so time does slow a bit closer to the center of the Earth due to stronger gravity. And faster when you are aloft in a balloon. There are some long discussions here about that.
In addition to mass, like the earth, energy and pressure also increase gravity and consequently slow time a bit...so in theory a stretched rubber band (more potential energy) is attracted just a bit more strongly to Earth due to increased mass/energy and time slows ever so slightly nearby.
LawrenceM said:Zapper's post was a bit harsh, but he makes a good point. I think this forum is meant, among many other things, to help fill in academic gaps that enthusiasts like you and I have. But you have to start with a question and not jump in with a speculative theory, or else the academics will blast you (as I’m learning). I’ve asked a couple of very basic questions on this forum and have had extremely helpful and respectful answers posted back to me in short time. There’s an amazing collection of minds on here that are more than willing to share what they know.
Time theory is the study of time and its relationship to various factors, such as speed, aging, and possibilities. It explores the idea that time is not a constant and can be influenced by different factors. Speed, specifically, can affect the perception of time, with faster speeds causing time to appear to slow down.
Aging is a key component of time theory as it is a measure of the passage of time for individuals. According to the theory, time can feel like it is passing at different rates depending on a person's age and their perception of time. This is due to the fact that as we age, our perception of time changes and can feel like it is moving faster or slower.
While the concept of time travel is often explored in science fiction, it is not currently possible according to time theory. The theory suggests that time is a linear progression and cannot be reversed or altered. However, some theories suggest that time travel may be possible in the future through advancements in technology and understanding of the universe.
The theory of relativity, proposed by Albert Einstein, is closely related to time theory. It suggests that time is relative and can be influenced by factors such as gravity and speed. This supports the idea that time is not a constant and can be affected by different factors.
Time theory has many practical applications in various fields such as physics, psychology, and technology. It can help us better understand the concept of time and how it relates to our daily lives. It also has implications for space travel, as understanding the effects of speed on time can help us plan and execute long-distance journeys. Additionally, time theory can also aid in the development of technologies that rely on precise time measurements, such as GPS systems.
