Thanks, I will follow up on this

Point taken, that makes sense, the more I think about it.

Thanks, it actual cleared a lot of air. It raises more questions too, but I guess, I might have to crack open a few books and sort them out for myself.

I think, it can be re-framed as "Do we know about any substance through which light can travel through without any attenuation?" To which a good enough answer would be optical fiber. The point is light, being light, can die down as it progresses through a media, where as the current we think of...

I live in horrific details, thanks for that ;) However, what used to confuse me were the articles claiming, it would take me almost 40 years to get there even at light speed or 99.9% of it. I don't even care if my rocket gains so much mass because of high velocity that it turns to a black hole...

So, I have been thinking about TRAPPIST-1 and how far away that system is from us. It is 40ly away from Earth, according to our frame of reference. This is often put in a way that makes one think that even at speeds close to that of light, it will take almost 40 years to get there. The muons in...

No, they interfere, if that's what you want to call hitting. Do light waves scatter each other? I don't really know.

Nope, they would be repulsive! It requires opposite directions of the force to induce attractive forces. I may be confused, but see it for yourself take magnetic field from one of the wires and see it's force on another wire with current in the same direction

First of all, there would be a few concentric lines of forces around the center of the individual wire showing that the wires would have a slight repulsion among themselves but it could be the case that these lines of forces could be of little or no importance if the loop is far away from the...

For the purpose of mathematical simplicity, it is assumed that, when the body is undergoing translatory motion only, the vector sum of all external forces act on it's center of mass. However, as you rightly pointed out, it is implausible to take this a general principle. Take the simplest case...

It might be a good time to point out that light, or for that matter any quantum mechanical entity, is neither a particle nor a wave they just follow equations which, in a classical sense, are attributed to waves and particles. It's time we stop publicizing interesting experiments like this in a...

Couldn't have said it better myself. That's exactly what I interpreted when I read about the experiment (Although my knowledge in quantum mechanics is fairly rudimentary.) But what concerns me more is the wave the experiment is publicized by making claims as they did at the webpage I visited...

Recent claims by scientists at EPFL suggesting that they somehow manged to photograph light simultaneously as a particle and as a wave raises more misconceptions than ever. The experiment on it's own is an excellent example of recent improvements in technological and experimental techniques, but...

Thanks, davenn. Your hospitality means a lot :) P.S I don't understand quantum mechanics any better.

I'm a computer science and engineering student with an interest in quantum physics, I expect to learn a lot from you all and hope to contribute a little of what I know to this community as well.
