what if you're moving toward the clock?

You cannot travel in a circle at the speed of light. That's what particle-colliders try to do - get particles to approach the speed of light as they go around a very large-radius circle. You need to look at the equations of special relativity. An enormous amount of energy is required to get particles in a collider to approach the speed of light. To approach even minutely closer takes a gigantic increase in energy. The equations of special relativity state that to accelerate a finite mass to the speed of light requires infinite energy. That's the whole theoretical reason for assuming photons are massless -that they cannot have a finite mass because they travel at light speed.another curiosity is that if i were to travel in a circle at the speed of light (with no gradual acceleration), would i see my perceptive self upon my return to the initial starting position, but there would be no tangible presence of myself?
Would this mean an infinite compression of space? Could the laws of optics describe these distortions?Gurrb wrote:the clock is simply a symbol of perception. ideally, the velocities of the observer and the observed would have to combine to equal the speed of light in a hypothetical space (in a vacuum). if we are moving away from the clock at the speed of light, then light (the clock and its hands) does not seem to change--there is no refreshing. if we are to move toward the clock at the speed of light, time would visibly speed up, but only to a certain extent. it's obviously a difficult thing to imagine, because this would be akin to time travel, in a sense. obviously, the image of the clock would be already travelling to the observer at the speed of light (in a vacuum, remember).
light is a physical phenomenon that doesn't encompass all the exists, but it allows all the exists to be perceived.

ostensibly, there are many questions that are unanswered in our physical universe and a simple explanation will never suffice on a whole.
these are merely hypothetical, thought experiments. i'm quite aware of the implications attached to traveling in a circle. let's say these are devoid of the common physical constraints of our world, except for those that pertain to light (i.e. light can only travel at a certain speed)cousinbasil wrote:You cannot travel in a circle at the speed of light.

You also have to grasp that travelling in a circle even at a constant speed requires acceleration. This acceleration always would be in the direction of the center of the circle. If you drive a car, you know this. When you go around a curve and feel like it is going to get out of control, you do not hit the brakes in the curve - you ease on the accelerator instead.
Actually light can be slowed down and bent.Gurrb wrote:these are merely hypothetical, thought experiments. i'm quite aware of the implications attached to traveling in a circle. let's say these are devoid of the common physical constraints of our world, except for those that pertain to light (i.e. light can only travel at a certain speed)cousinbasil wrote:You cannot travel in a circle at the speed of light.

Satire: stationary reactions are the preliminaries. If co-existence with outer space has a mode, it is "FDY"

Is this a joke meant as an insult? Did Gurrb do something to you? Did I? Someone else?For further enlightenment contact your local previsions.
