Thanks Brandon. Transistors certainly switch but in a solid state way which is cool. In the article they are referring to it being like a relay. ie. "’This device is similar to electromechanical relays but operates completely with light". And, "nanoscale light conduits can be used to...

Which is exactly what string theory is attempting to do? And again as I say our cosmologists are coming up with new definitions of our universe. Blocking all new definitions isn't generally the way forward in physics. Resistance is certainly fine. The question then comes back to whether what...

Well, GR and SR actually could be considered to add two extra dimensions to equations couldn't they? I'm not talking about physical dimensions; though science does treat physical aspects mathematically. I'm talking about adding an extra dimension to the classical models which treated things in...

Thinking about it mathematically I wonder if it is possible to consider that Einstein added a second time dimension when he developed his relativity? Things no longer move with straight forward relative movement but now can move through 'time' at different speeds due to this added mathematical...

Could reaction (aka acceleration) be considered to be a dimension. Things don't just move through time and space; they also react to each other?

I imagine that we would have to move in such a way as to maintain our overall rigid or elastic shape shape in our space with maybe some fluctuation at the miniature level or something in and out of these 'tiny' dimensions? I wonder if the string theory dimensions are supposed to be 90deg to our...

Thanks Nabeshin. This then raises the question, which I mentioned above, as to what ties us inside our three dimensions? What excludes us from moving through those other dimensions as easily. The three space dimensions we attribute ourselves x,y,z don't have any preferred direction, as I...

Thanks Integral. By this it then perhaps becomes more logical to refer to extra dimensions. Maybe it is okay then for theories like string theory to have extra dimensions without needing to resort to physical 'braines' and such. I would wonder if the real ultimate trick is in trying to reduce...

Actually, I have a similar question (that I hope won't interfere with the original OPs question) so I thought I'd add it here. I can see us dividing our space up into dimensions of x,y,z and for myself - though probably not for others - I can see myself adding time as a dimension of movement...

I assume that I probably don't understand them precisely. Thanks harrylin for helping me to understand the answer I was after. I do also appreciate what you are saying ghwellsjr. I have read the efforts that they went through to co-ordinate time. Whether we synchronise clocks or not, I just...

I do find using common phrases an understanding trap as I find I read them and other laypeople read them differently even though there maybe be a textbook definition/explanation of what they are used for by professional to encompass. There probably are precise terms that are used to mean a...

That is sounding like how it works harrylin with the air/space-time being at rest relative to the observer or something like that? I think? I'm guessing? Another question... When you head towards a light wave you meet the light wave part way but how much time does it take to reach you. Does...

Thanks that is good. You've no-noed it but I like that idea of using sound to measure the arrival time of sound at the target as this is kind of like what I am wondering for light. The communication of arrival time has to be done by some means and generally that is emr (including current in a...

Thanks Ivy. That's a cool formula. Thanks for showing it for both to clarify the similarity. I am still confused... There still seems to be the matter that if you, the observer, are moving with the target you will be at a closer point to the light when the light reaches you traveling at c so...
