I HAVE CHANGED MY MIND!	01 Aug 2007 00:15 GMT	5
I HAVE CHANGED MY MIND! THE LIGHTCONE(LIGHT) AND THE INSIDE OF THE LIGHTCONE(TIME) IS TOGHETER MAKING GENERALZIED TIME!
life time of an atom	31 Jul 2007 22:45 GMT	32
atoms can lose and gain electrons, but overall what is tha lifetime of an atom? i cant see tha reason why a muon having a lifetime while an atom or a nucleus, protons,
Can we mark the points of "empty" space ?	31 Jul 2007 17:27 GMT	11
I think, the answer should be, Yes. I will give a simple example here. Let's consider that we send 2 identical EM sine waves of a constant phase-difference
Lorentz scalar and Lorentz invariant scalar are not the same thing?	31 Jul 2007 15:32 GMT	6
Correct?
relativity predicts absurdities - time travel	31 Jul 2007 15:20 GMT	2
what time travel? they say travel in tha past and travel in tha future but all these are ill posed differential equations, becus traveling bag in time means reversing time,
On spherical gravitational collapse and the stability of classical black holes.	31 Jul 2007 14:08 GMT	20
Adler, Bjorken, Chen & Liu give simple analytical models of spherically symmetric gravitational collapse in Am J Phys 73 (12) 2005 (with thanks to Steve Carlip for providing the reference). Amongst the examples discussed therein are a thin light shell falling
Temperature is not Lorentz invariant	31 Jul 2007 06:34 GMT	11
Correct?
Curvature vs matter by KST	31 Jul 2007 05:43 GMT	36
My general thinking is to begin with the 4th rank Riemann Christoffel (RC) Curvature tensor I'll denote R_abcd. If the RC tensor is zero then the field can be transformed to a state where the metric "g_uv"
why speed of light is not constant?	31 Jul 2007 00:01 GMT	10
light thro water goes slower than same light diverted thro air they can even brake and stop light, so it is not constant
what makes electrons fly and not staying still?	30 Jul 2007 23:09 GMT	14
why are electrons flying around nuclei and they are not staying still? what is tha driving force making electrons fly? are electrons flying by them self or is something
why light is electromagnetic when she dont act like an electromagnet?	30 Jul 2007 20:00 GMT	14
if i take my electromagnet out of my relay, i can attract my keyring with him why i cant atract anything with light if she is an electromagnet?
What happened to HAMMOND?	30 Jul 2007 18:39 GMT	2
I used to like to check in here and laugh at george hammond's insanity. where did he go? another stint in the loony bin? marcus
Electron doesn't obey the right hand rule here???	29 Jul 2007 22:14 GMT	7
At the web link below: the electron gets fired from an electron gun and it's deflection doesn't obey the right hand rule? In fact it deflects towards the magnets and in relation with it's spin? http://www.upscale.utoronto.ca/GeneralInterest/Harrison/SternGerlach/SternGerlac h.html
is gravity really physical geometry or only an interpretation	29 Jul 2007 18:01 GMT	1
this is becus if gravity were geometry, then this automatically would imply physical real shapes for instance, a sphere, like our sun or earth, has gravity
are the Space-time dimensions continuous or discrete?	29 Jul 2007 17:24 GMT	12
I am new in this newsgroup. I don't have a lot of knowledge in physics. I searched briefly messages in this newsgroup but could not find an answer to the question:
