Nope, more like an observer "riding" a photon. Or an observer traveling at the speed of light, theoretically.

So, am I to understand that a photon can not be an observer, or have an observer? (https://www.physicsforums.com/showthread.php?t=511170)

Thank you very much for the responses. I'll need to find a frame of reference that contains some spare time to read all the refs :smile: Thus I'll give some response after updating my background knowledge on this subject.

Hi All, Before I state my questions, let's test my assumptions / background knowledge: (The classical explanation?) Aaron and Bongani (sorry Alice and Bob is so boring) sits in a spaceship near a black hole. Aaron gets out and speeds towards the black hole. Aaron will experience...

BTW, what will the impact be if the universe is infinite or finite (lets say 10x billion light years, where x is a very large number) Or even is x is not that big number... Are we going to fall of the edge of the earth, erm... I meant universe. We can't even send a man to Mars yet or...

The definition according to the mighty Wikipedia: http://en.wikipedia.org/wiki/Universe" As for an infinite "thing" expanding, it makes a lot of sense; the observed distances of the "points" inside this "thing" will increase. (I think I read that it is not only the mass objects /...

http://en.wikipedia.org/wiki/Olbers%27_paradox#The_mainstream_explanation". Note the part of the "fabric" space expanding (not just the distances between objects) If I understand the Big Bang theory; It all started with a finite amount of energy. If space is finite as well then what is the...

Ah, thank you Deuterium2H

I don't think time is constant (either is the perception of time). Atomic clocks runs at different times when at different gravities. (gravity field strengths)

Checking my assumptions: 1. Matter create space? 2. Matter expanse space? 3. Matter needs space to exists?

Uhm, I'm outside the USA thus had to look it up: http://www.upi.com/Top_News/2009/01/29/Los-Alamos-warns-of-beryllium-exposure/UPI-72381233231615/"

Thank you for the reply. (Seems like you'll be around for a long time; (T1/2)1.5×1017 years) P.s. They mine you near Rustenburg tʌŋstən

Uhm, not really :blushing: And I suppose that a huge magnet will not help much other than push up the cost

So, collection of them for manufacturing fuel or energy will not be a good idea, even if one is already in space?

Uhm... To expand my question: What are these particles (to start off)? (Atoms, sub atomic particles, etc) Can these solar wind particles be used for anything useful? (Useful as in building stuff?) (The question was so clear in my mind, but I guess it is just one of those days :smile:)
