CraigD Posted June 28, 2011 Report Share Posted June 28, 2011 Does an electric field effect time?I assume you're asking if electric fields have a time dilation effect similar to gravitational time dilation. I know of no credible theory predicting this, or any empirical evidence suggesting it. So, no. Quote Link to comment Share on other sites More sharing options...
Little Bang Posted June 29, 2011 Author Report Share Posted June 29, 2011 No, I'm asking if you move a clock into a strong electric field does it affect it's rate? Quote Link to comment Share on other sites More sharing options...
coldcreation Posted June 29, 2011 Report Share Posted June 29, 2011 No, I'm asking if you move a clock into a strong electric field does it affect it's rate? Hey Little Bang, That would be an effect similar to gravitational time dilation, as CraigD pointed out. Just out of curiosity, why do you ask? Are you thinking there exists such an effect in strong electric fields, and if so, for what reason would you suspect the effect to exist?

Little Bang Posted June 30, 2011 Author Report Share Posted June 30, 2011 If there is an effect it suggests a possible reason as to why a gravity well dilates time. I have offered in other posts that gravity is an artifact of time dilation and not the other way around. If mass dilates time then the electron will dilate time so the real conundrum is why.

Rade Posted June 30, 2011 Report Share Posted June 30, 2011 see this paper, perhaps it helps with your question: http://ccdb4fs.kek.jp/cgi-bin/img/allpdf?199107099 === Also, it appears the experiment has been conducted....see report below in red text. "Advances in laser technology and the field of quantum information science have allowed researchers to demonstrate Einstein’s theories at much more ordinary scales. The researchers used two optical atomic clocks sitting atop steel tables in neighboring labs at the National Institute of Standards and Technology in Boulder, Colo. Each clock has an electrically charged aluminum atom, or ion, that vibrates between two energy levels more than a million billion times per second. A 75-meter-long optical cable connects the clocks, which allows the team to compare the instruments’ timekeeping. In the first experiment, physicist James Chin-wen Chou and his colleagues at NIST used a hydraulic jack to raise one of the tables 33 centimeters, or about a foot. Sure enough, the lower clock ran slower than the elevated one — at the rate of a 90-billionth of a second in 79 years. In a second experiment the team applied an electric field to one clock, sending the aluminum ion moving back and forth. As predicted, the moving clock ran slower than the clock that was at rest."

CraigD Posted July 1, 2011 Report Share Posted July 1, 2011 Rade that was very interesting. Can you provide a site that I might read about the second experiment?The paper is C.W. Chou, D.B. Hume, T. Rosenband and D.J. Wineland , ‘Optical Clocks and Relativity’ Science 24 Sep 2010, page 1630-1633, available online here. You must have an AAAS account (personal, organization, library, etc) to read the full article. It’s been mentioned in lots of free articles, such as This 23 Oct 2010ScienceNews article. The paper doesn’t propose or support that an electric field effects time in and of itself. Instead, Chou et al show, using a pair of very precise atomic clocks, that by varying the electric fields used to contain the clocks’ aluminum ions so that one of the clocks ion has a greater back-and-forth movement, and thus a higher average speed, than the other, the time dilation predicted by special relativity is measured. It’s reminiscent of the 1971 Hafele–Keating experiment, where four atomic clocks were flown eastward and westward around the world on commercial airliners, but the precision of the atomic clock Chou et all use is so much more precise than previously used ones, its possible to detect a tiny time dilation effect from smaller “tabletop experiment” speeds. Like the Hafele-Keating experiment, Chou’s is primarily a test of atomic clock technology, not of special relativity, which is confirmed to greater precision by other experiments. Somehow I missed this cool experiment - ironically, because at the time, an AAAS account screw-up was causing me to get buried in print copies of Science magazine. :) Thanks, Rade for finding it, and LB, for bringing up the question that led to it. :thumbs_up Quote Link to comment Share on other sites More sharing options...
Little Bang Posted July 1, 2011 Author Report Share Posted July 1, 2011 Yeah, your right. Wish NIST would perform the experiment to test if an electric field affects time. Quote Link to comment Share on other sites More sharing options...

lawcat Posted July 1, 2011 Report Share Posted July 1, 2011 Gravity does not bend space, gravity is the the field of bent space itself. Mass is the space bending agent. As a corollary, electric field would be a field of bent time itself. Charge would be the time bending agent under that hypothesis, so to connect Einstein to Newton and Coulomb: Force of attraction in space = mass1 x mass 2 x G constant/distance^2 Force of electric attraction = charge 1 x charge 2 x constant (based on permittivity of space) / distance ^2. The problem of experimental proof is the "nanoscale." But I suppose, if you have a capacitor, two long charged plates, and you send light to travel through the electric field, you should observe inconsistency between expected and observed speed of travel that would indicate a longer or shorter distance based on the speed of light. In other words, as a corollary to gravity, bent space causes appearance of acceleration, bent time would cause appearance of dillation in distance.

CC While reviewing basic calculus, I noticed that the curve (1+t^2,t^2,t^3), which clearly has a cusp at (1,0,0), has a derivative curve (2t,2t,3t^2) which is clearly smooth. This struck me as odd since differentiation usually seems to turn cusps into discontinuities, whereas integration smoothes out a curve, especially a curve described by polynomials. In fact, in general I have always taken a curve to be smooth iff it has a continuous derivative, which this curve has, and yet a cusp cannot be smooth in any sensible sense. I suspect the explanation is relatively simple - just something I'm missing. Quote Link to comment Share on other sites More sharing options...
write4u Posted October 19, 2022 Report Share Posted October 19, 2022 (edited) Why does everyone assume that time is a field independent of space? AFAIK time is an emergent result of the duration of a continuing chronological event in space. Time does not exist independent of the existence of space. So if there is a faster or slower expressinon of measurable time, it is the result of a continuing spatial (physical) condition. Gravity itself is also not a dimension, but a result of space warping. So it would be perfectly logical to propose that time and gravity are independently affected by spatial distortions, but will both become expressed in a distortion of space.

The gravitational wave expands over more gravitons, it's field drags them one meter per second for six minutes forward in time, this one meter per second drag decreases the length it drags the object by the inverse square law. You notice that if another wave is more intense it will drag the objects two meters per second. The first set of objects is time-dilated relative to the other two. Now backward in time this six minutes looks like the gravitational wave receding and it's field influence over the other gravitons strengthening by the square law. We assume that it's always going to perform the same sequence going forward in time even if at a later date the arrangement of gravitons is perturbed by an outside GW. However, we notice in several quantum effects; such as entanglement and eraser, that this is not the case. Let's say start of the six minute clock is point A and the end of the six minute clock is point B. If you effect the arrangement of gravitons at point B, the receding gravitational wave will manifest a different arrangement of gravitons at point A, and thus result in a different arrangement of gravitons at point B. A to B is no more valid than B to A, except for in our perception of time resulting in memory of point A when we are in point B, however it is possible that a life form remembers point B when it's at point A, the opposite of our perception of time. It is also possible a lifeform doesn't have memory but rather experiences it's entire existence at one time, however, it couldn't navigate terrain in this instance. I'm saying our perception of the past could be inaccurate at the quantum scale, but sufficient or consistent enough to navigate the macroscopic world.

I would say any fundamental change in the stationary position on the most fundamental level could be an expression of time or duration.

I agree, but time is not a causal function. It is a result of a chronological duration (unfolding) of something physical. Moreover, time is a variable, not a constant. Time itself is immeasurable. Time associated with specific objects or sets has names: Note: time does not exist ahead of the present. The future is a timeless, dimensionless, permittive condition. Time is an emergent result of duration of something. There is no time in the future. The future does not yet exist.
