1. Q: Light slows as it passes through water or
glass, causing it to bend, but how can it

A: This is impossible in today's science. No object in nature
can speed up of its own accord after being slowed. A bullet
doesn't spontaneously speed up after it is slowed by passing
through a wooden block, so how does a photon of light
block? Also, continuously shining a light beam through a glass
block will heat it, creating the further mystery that the beam
actually loses energy as it passes through the glass, yet still
manages to accelerate to its original speed upon exit. Today's
science cannot explain this mysterious everyday occurrence.

Here is another related mystery: Bounce a light-beam between
two parallel mirrors at a slight angle so that the beam bounces
along the mirrors in a zig-zag pattern. How many bounces
will it take before the light beam loses energy and slows down
appreciably? 1000 bounces? 10,000? Of course, we know that
the light beam will never slow down no matter how many times
it bounces back and forth, despite the well-established fact that
light imparts a small momentum punch when it bounces off
objects (the principle behind solar sails). So, how does a single
beam of light impart countless momentum punches as it zig-
zags between the mirrors, yet still manage to emerge afterward
at the same unchanging speed of light? According to today's
science this is an impossible energy-for-free event.

3. hmm isn't light still moving at the same speed? it's direction is just bent?

Simply because light is an electromagnetic wave, a disturbance in space - air, vacum, or a glass - so you can't compare it with a bullet's speed and behaviour. The EM Wave's behaviour it's very well explained with the Maxwell's equations. Basically, an electromagnetic wave - light - is the result of the interaction of electric and magnetic fields, which are the ones that provide the "speed" to it.

And of course the wave looses energy on it's path, it is called attenuation - decrease in intensity of the signal - and it is irrelevant to the propagation speed of the signal.

Houm...

Don't mistake the speed of light with speed of dispersion...

Light always mvoes at a same speed -the speed of light. Yet it may be "delayed" when it passes through a transparent matherial. This si because whenever a photon hits an electron form a atom, this electron ill momentrily "raise" to a higher valency level, then will emit this "extra" enrgy in the shape of a photon. This photon will traverse at light speed, until it hits some another elctron and the absorbtion-energizing-emisson process is repeated; well then, this absorbtion-emission process takes some time, and so being absorbed and emitted "slows down", or "delays", the photons.

Think of it like a F-1 racing car running in Montecarlo during the GP and then picture it between the normal traffic at Montecarlo...

The pace of "slow down" is proportional to the density of the matherial; fai, in a extreme case, the photons created in the core of the sun take a whopping ONE MILLION YEARS to get through the untold chaos of the sun's structure and be actually emitted outside of the sun.

Here is another related mystery: Bounce a light-beam between
two parallel mirrors at a slight angle so that the beam bounces
along the mirrors in a zig-zag pattern. How many bounces
will it take before the light beam loses energy and slows down
appreciably? 1000 bounces? 10,000? Of course, we know that
the light beam will never slow down no matter how many times
it bounces back and forth, despite the well-established fact that
light imparts a small momentum punch when it bounces off

beam of light impart countless momentum punches as it zig-

Nae. Some photons perish in each bounce, and the beam becomes dimmer and dimmer. The "punch" comes from the photons who are absorbed and not emitted back. A single photon bouncing succesfully wouldn't lose any energy until it was eventually absorbed. In a ultrahigh quality mirror like those used in professional Astronomy, about 0,001% of the photons are absorbed in each bounce...

While the speed of light does not change, its energy can. Each photon striking the mirror can give up a little momentum to the mirror, (the mirrors will begin to move apart.) In doing so, it loses some energy. The energy of a photon is determined by its frequency, so the photon will shift to a lower frequency. As the light continues to bounce back and forth, it shifts to lower and lower frequencies, eventually leaving the visible spectrum completely. That is assuming that there are any photons left after losses due to the imperfection in the reflectivity of the mirrors.

I think both of your misstatements have been explained to you. However, what does any of this have to do with some "The Final Theory" book ? What book are you talking about ?

IMO. If this http://www.thefinaltheory.com/images..._Chapter_1.pdf is the book that you mean, then the answer is quite simple. This book is crap. It misrepresents the laws of physica and many of its statements are just plain false.

8. FYI - Four year old thread, guys.

9. I've seen similar things happen a few times now and I'm profoundly curious as to how (someone manages to find a several year old thread and posts a fairly contentless response). kakarot, how did you come upon this thread?

Youthful enthusiasm combined with neophyte ignorance.

11. the light gose back and forwad in time and stabelize on the ending object .
thanks .

Ophiolite! You are being generous!

13. I'm just curious as to how someone can find a four year old thread without realizing that it's way too old to reply to.

Use the search function to look for topics that interest you and not notice the date.

Not realise the etiquette involved.

Think the topic worth reviving.

15. I suppose so. I just figured that seeing something on page 3 of a search might be a clue, but maybe the search was specific enough that that didn't happen.
