I was wondering if one were to travel at the speed of light, how fast or slow would they age. Would they age at the same speed as on Earth because the speed of light is relative or would they age slower due to time dilation thanks for the replies
Nothing is impossible just highly improbable....
Hi, you guuys thanks for all of the responses but I just want to know if someone traveled at the speed of light for 100 years how much he would age. Would he age the same or would he age slower. Thanks
I could not help notice that my example of switching off the Higs field has been ignored....... if the Higs field is responsible for giving objects mass and you switched it off somehow then surly that opens up new possibilities? PMB; if we fully understood our universe then I would fully agree with you........
The simple answer is, anything moving through space at c, equal to the speed of light in a vacuum, experiences zero time flow. If you were to travel at the speed of light, you would experience no time.
Actually, if you consider matter and energy in spacetime... EVERYTHING always travels through spacetime at c.
That’s not true and is based on the misconception of a spacetime interval being identical to “distance” and then incorrectly calculating velocity by dividing a spacetime interval by the spacetime interval with a factor of c not canceling out. You can call the result you get anything you’d like with the exception of “speed” or “velocity” or “traveling at c” since all these things already are well defined and already have well defined answers which are different than you’ve given. You just can’t say that its moving through spacetime with speed c. Those terms are already defined and cannot be redefined in the same breadth.
The speed that we perceive to be c is a function of the angle between the space axis and the time axis. We only see a 3-space cross section of the 4-space trajectory and the tangent, distance/time = c.
c is a constant. That's not a property of light, that's a property of spacetime. It's a matter of geometry... the equal angle between space and time corresponds to c.
You can think of it as a tangent a/b, distance/time. The angle always appears the same, to every observer.
c is a constant. That's not a property of light, that's a property of spacetime.
PMB, I believe I owe you a coffee

You're saying that someone chose what the properties of spacetime would be to ensure c is the same for all observers?
