Light cannot escape the universe (redux)

<b>The equation for gravitational time dilation proves that light cannot cross a gravitational potential of -.5c^2 in coordinate time.</b>

"It is usually taken for granted that the processes of mathematics are identical with the processes of reasoning, whereas they are quite different. The mathematician is more akin to a spider than to a civil engineer, to a chess player than to one endowed with exceptional critical power. The faculty by which a chess expert intuitively sees the possibilities that lie in a particular configuration of pieces on the board is paralleled by that which shows the mathematician the much more general possibilities latent in an array of symbols. He proceeds automatically and faultlessly to bring them to light, but his subsequent correlation of his symbols with facts of experience, which has nothing to do with his special gift, is anything but faultless, and is only too often of the same nature as Lewis Carroll's correlation of his pieces with the Red Knight and the White Queen - with the difference whereas Dodgson recognised the products of his imagination to be wholly fanciful, the modern mathematician imagines, and persuades others, that he is discovering the secrets of nature." <br />-- Professor Herbert Dingle, <i>Science at the Crossroads</i> (1972)<br /><br />BTW: "The astrophysicist, Dingle, knew what he was talking about. He wrote the entry on Special Relativity for the Encyclopaedia Britannica for some years before he realized the logic was flawed. His many attempts to find an expert who could answer his simple question without resorting to metaphysics or answering some other less awkward question convinced him of the danger we face if we continue to allow mathematical theorists to dominate physics -- hence the title of his book. But the juggernaut of science sped through the crossroads, unheedful of the red lights." -- Black Holes Tear Logic Apart <div class="Discussion_UserSignature"> </div>

The real speed of light = 299,792,458 meters per proper second = (299,792,458 / Time Dilation) meters per coordinate second<br /><br />Coordinate time represents absolute time as in GR.<br />Proper time represents time as percieved by the observer in both GR and SR.<br /><br />In hyperbolic space, there is positive gravitational potential energy causing an expansion. Time Dilation would be less than 1.<br /><br />The coordinate time is the real time. Velocity Time Dilation and Gravitational Time Dilation should instead be interpreted as a slowing of local processes.

This is simple, check this out:<br /><br /><font color="yellow">In general relativity, clocks at rest run slower inside a gravitational potential than outside.</font><br /><br />Ok, so what is this clock they speak of?<br /><br /><font color="yellow">A light clock is a clock that clicks every time a light pulse emitted from one location returns to the same location after reflecting off a wall.</font><br /><br />Simple, there are no ticks at the event horizon. That means that the light never hits the wall again. So what does that mean? It is clear then that the permittivity and or magnetic permeability of freespace is affected by the gravitational field, and so is all other energy that comes in contact with it. Hence, the speed of light is thought to be constant in all gravitational fields, well that's not actually true (true only locally), as all perception in a gravitational field is affected as well as the movement of light.

i'm just pondering the premise that "light cannot escape the universe." this implies right away that the universe is closed and finite. so how could it escape anyway, regardless of any computations? if the universe, supposedly the lap of all existence, had a beginning, is closed, harbors all of creation, then how could anything that is a product of such an existence escape it?<br /><br />if the universe, conversely, were infinite, then light cannot escape it again because it would not be able to physically overbear such an infinite state of existence. <br /><br />furthermore, let's say light can escape a closed universe. then what? it escapes into what? nothingness? <br />
