A couple of simple questions I'm boggled by... Suppose two people, each in his own craft, set apart by significant distance and stationary to each other. Both crafts accelerate to 1/2 light speed from their origins directly towards each other. This results in a relative speed between the two...

I can't speak directly to your question, but your hypothetical explanation of how dust particles will behave is defining the "shape" of the universe by the locations of the matter within it. This is what confuses me - while I clearly see why things will move as you suggest in your statement, it...

Exactly my point, in a lot fewer words. :) But instead of just trying to debunk the concept based on logical fallacy, I am intruged by why anyone would find it necessary to define a shape for the universe. What observations have led to someone thinking that parallel lines aren't really...

I appreciate your explanation and taking the time to write it. From your explanation it sounds as if the shape of the universe is still under debate, and not surprisingly so. When I ask the question, "What shape is the universe", such a question ultimately requires one to define the...

As far as I understand, we know what we see. When we look at the universe, we don't see the space. We see the objects. We see the distance between objects, but we don't see the space between them. When one speaks to the shape of the universe, they can only conclude based on the objects...

How can we define the universe as having a "shape"? I'm ignorant, so please excuse me. I've read time and time again over the years on the topic of "the universe" and keep coming across the concept of it having a "shape". Terms like "curved" and "flat" continue to come up and while they...

Van: Being so thinly veiled gives the impression of having thick skin. Let's test the theory. ;-) The point I made was that the theories in QM that try to explain why something does what it does aren't intended to create greater confusion. In most cases, a reader will either improperly...

I see. How about in the case of using a much higher voltage power supply with this tube - would make it analogous to a CRT and electrons will flow through the tube, which I know would work. From your description the reason for the flow of electrons is because there is a sufficient...

Call them photons, virtual photons, aetherites, or just thingies, it really doesn't matter. There exists a force carrier which allows the difference in charge to affect physical matter over distance, without direct contact. The negative electrostatic component of the electron is attracted to...

Seems to me that at a certain point in a person's study of these things, one gets lost and unable to separate the difference between theory/model and reality - as if these theories/models are explicitly what creates reality. Dont get lost - the models/theories are simply tools to understand the...

Your question may need further refinement in order to answer your question. My initial response to your question: The reason each person sees the ball in the room in the position it is at is simply because the ball is physically located in that position AND the light reflected off of it is...

Hypothetical device: Vacuum Tube Two tungsten electrode plates at each end The work function of tungsten is ~4.5V. Lets attach a power supply to the two electrodes with a potential difference of 4.0V. Question is, by biasing the two plates in such manner, is the thermionic discharge...

Perhaps your view of the complexity of building this is not the same as my own. I've built far more complex systems before. The time and materials to build such a device isn't the issue. There is a lot more math involved which I have not gotten to at this point, there are other...

Thanks for the reply - I left a lot of other information out as it wasn't pertinent to the knowing whether or not these free electrons will absorb the incoming light and be propelled through the loop. 1) Building a heliostat is nothing difficult, I have the engineering experience to build...

Got an idea for something that I think with the abundance of bright minds here I will find the oversight that makes this idea NOT work. :) In short: Solar Collector - parabolic dish Focused light is directed into a solar generator device. The device is as follows: Quartz glass tube...
