 That's easy, Honey, I can move back and forth, up and down, and right and left.

Can't you? 

 


By my basic mathematical skills, that only makes 3 dimensions.


 Worse still, saying she can do it is not evidence that she can actually do it and is certainly not proof!


Quite right.  I remember explaining to a friend of mine how originally numbers had to be proved to exist.  He didnt get it - ''Of course 'one'  exists and 'two' is just twice as big'' so I gave up.  Sometimes so-called obvious things need a bit of digging into.  That's why I originally said that things are too complicated to understand.  In fact, you can't even prove you exist at all - you could be uploaded (tongue in cheek).  I guess the fact that you believe yourself to exist proves that something exists.  Cue the philosophers.

 All I was doing was answering astophsyics question from a teen. not claiming Philosophy. I thin you haver missed the point.l Just like a man.

And yet if we were to make an offhand remark about women...*shakes head*

 

Double standards all the way, I suppose.

 No, I was quoting men about women, since I am one!

The temperature definition may come throught energy of particles or waves .. but, seems no one of them comes out from this object .. we may say that, this object is out of the temperature deffinition, it has no temperature ..


 "No-one of them comes out of this object" True, but Hawking radiation makes it SEEM that way.


I had a look throught the definitions : of this radiation

http://en.wikipedia.org/wiki/Hawking_radiation

but seems to be the only theoretical hypothesis .. of the possible emissions ..

it is quite clear to me that the Unworthy Bishop from Knightsbridge (Hey! Bishop - Knight! I wonder if that is made up?) is violating the rules here with abusive. The message clearly is: "Send the kind of messages you would like to receive".

My question is.. if the light has a mass E=m*c^2, so it may be keeped on strong gravitational field as a black's hole one, and.. if it's keeped there what's means that?.. does it stop?.. than it has no mass.. or may be te energy is changing proprietes from light structure to another one, more stable ?.. (same for particles mass).. looking for your ideas on this way..

I'm getting tired of seeing these threads all the time. When are you people going to realise that Kazue doesn't care the least bit about science, physics or womens rights. Kazue is the kind of person commonly known as a troll. He/she has already been proven wrong several times so just let it go.

 

Don't feed the troll people.

Hahaha.This is you.I recognized you in your posts and your multiple accounts.Profiles of your multiple accounts...  but why now again on this great chess site? Is your life so sad and boring?

Why? Why?

 I know why why why, because all of what you say is twaddle, twaddle, twaddle. Can you prove prove prove or are you just jumping jumping jumping to the wrong conclusion conclusion conclusion because you have a complex complex complex???

just finishing the idea.. I think that light is like electron on the atom, once it captured by black hole.

The energy of light quantum: 

E=mc^2.

The force of gravity interaction light - hole is:

F1=GMm/r^2 also, F2=mv^2/r, were r - the critical value for the phothon orbite-radius, G- the garavity constant of interaction.

F1=F2, and v=c ,  => GMm/r^2=mc^2/r => GM/r=c^2 

we reacieve that M/r - constant value for electromagnetic waves, and it doesn't depend of it's energy, frequency.. so, the radius is..

r = MG/c^2. nice relation-ship

some numerical computations..

if M=1.9891 ×1030 kg (1sun mass.. http://en.wikipedia.org/wiki/Sun)

G=6.6742x10^(-11) m^3/kg/s (http://en.wikipedia.org/wiki/Gravitational_constant)

c= 299,792,458 m/s

than we recieve..

r= 1.477 x10^3 m, or r=1477m from the hole center.

murometzyx

this value is totaly agree with the previous independent results which I found it right now on the wikpedia : GM/c2=1.48km(M/M0)

http://en.wikipedia.org/wiki/Black_hole#Sizes_of_black_holes

please check.

 I guess you'd need to have her tell you how to walk then, and jump.

 Actually it does not matter that you think that light is like an electron, because it isn't. A light photon is a boson, an electron a fermion. Please learn some basic physics, like, "it is a fact that..." rather than "Well, I think that...."
