Oh alright thanks, the fact that it doesn't make 'sense' I can understand because I have seen a lot of things in quantum mechanics that are....shall we say.... 'spooky'
However, I thank you for that link its very helpful!
Thanks,

I was reading this article, http://www.nature.com/news/2009/090122/full/news.2009.50.html, and it was talking about how they 'teleported' a Ytterbium ion (Yb+) and mid-way through the article it said that they had to destroy the quantum state of the original Ytterbium ion and they did that by...
Because light bends due to gravity, as can be seen in Gravitational Lensing, if gravity responds to mass and light is bent by gravity, does that not imply that the photon is NOT 100% massless?? That the photon indeed has a very tiny amount of mass?? Because if light bends due to gravity, then...
Superluminal Neutrino Breaks SR and GR...???
I have reading a lot of articles and editorials about apparent neutrinos that went faster than the speed of light by 60 nanoseconds, I read some that say yes and no, so I'm a bit confused. So is it true?? Are there neutrinos that went faster than the...
I have seen and read a few different versions of the Einstein field equations (EFE). For example; R_{\mu\nu} - \frac{1}{2}g_{\mu\nu}R = - 8\piGT_{\mu\nu} , R_{\mu\nu} - \frac{1}{2}g_{\mu\nu}R + g_{\mu\nu}\Lambda = \frac{8 \pi G}{c^4}T_{\mu\nu} , and 8\piT_{\mu\nu} = G_{\mu\nu}
So which one is...
Oh ok, thank you very much lavinia, you answered all of my questions regarding the natural existence of Euclidean geometry! Now, I have one last question, if Euclidean geometry essentially does not exist, then is pi (∏) still practically useful, because all circles are generally spherical...
Thank you daveb, that explanation is very helpful!! :D
When I say 'naturally' I'm not sure how much simpler to say it, does Euclidean Geometry occur naturally; is it apart of nature anywhere in this universe??
Because when in the presence of a gravitational field (force), space is...
Can someone explain to me in detail, why the ratio of the circumference of a circle to its diameter is not equal to pi in non-Euclidean space!!
Also, does Euclidean Geometry exist naturally in this universe??
Thanks,

I disagree, from what I've read currently, it looks like there is NO SPACE that is empty. There's always some minute factor or field within it, either at rest or active. This would be where dark matter and dark energy come into play.
When solving with E=mc^2 what units should I use in the answer??
For example: (if I have an object with a mass of 43kg)
E=mc^2
E=(43kg)(299792458m/s)^2
E=3.86464727 × 10^18
Now here's my problem, do I include units of J/kg (joules per kilogram) or eV (electron volts)??
If someone could...
I say "purely empty" because "empty" has been used to describe a vacuum and yet the vacuum is not empty, like purely empty. There are some things inside, so I see that writing "purely empty" is showing that something is or might be purely empty and not used lightly as "empty" has been used. But...
Alright well thank you for your help all, I now understand that the space in the atoms is actually not purely empty, nor is there a purely empty area.
Thanks,
Al
Oh, well is it true to say that there is no real empty space, because quantum field theory suggests that there are quantum fields that pervade the universe, the vacuum is just a place where the fields and their particles are at rest, no?
So you're saying its truly a vacuum?? There's no energy fluctuations within it or some such, its just a blank vacuum? (And yes I know what "empty" means, no need to be condescending.)
I've always heard that atoms are 99.9999996% empty space, now I am wondering is the empty space between the orbiting electrons and the nuclei just empty; a vacuum...?? My question is: What is in the empty space of the atom?(for I doubt it is actually purely empty) What is in the space between...
My question is simple: Are there any massless
My question is simple: [B]Are there any massless particles?
Because I've now found out that the photon, which I always thought to be massless, actually has an extremely small amount of mass. It is something along the lines of a billionth of a...
