natural recession speed after The metric expansion which exceed the
"speed of light" c and to distances which exceed c times the age of
the universe,
can some one explane this to me like i'm a two year old please I dont
Spaceman's muddle10 Oct 2008 23:53 GMT112
In case you've missed on the kerfuffle...
Spaceman has essentially asked the following question:
For a clock that is approaching an observer, what will happen to the
clock's rate as seen by that observer? Will it be

been likened to the passage of an arrow, "the Arrow of Time". There have

of last knowledge in this unified theory.
Is there cheating in relativity?09 Oct 2008 18:39 GMT24
I think there is lying or cheating in the theory of relativity.
Specifically, cheating happened in the textbook Fundamentals of
Physics, 6th edition, published by John Wiley and Sons, jointly
authored by David Halliday, Robert Resnick, and Jearl Walker.  On
Gravitons verses general relativity.09 Oct 2008 16:23 GMT24
Has relativity and various qm theories come to agreement on how space-
time curviture translates into gravitons or are they at odds?  String
theory claims to unite both theories. How does it do this in the
graviton / curved spacetime arena?

Proof that Relativists Do Not Understand Relativity.06 Oct 2008 21:13 GMT101
Einstein's second postulate says that light travels across space at a speed
which is independent on its source speed. It also claims that no matter who
measures that speed, the answer will always be c.
I have animated the second postulate with a Vbasic program (requires windows).
Why relativists don't understand  Einstein's 1905 mathematics.06 Oct 2008 19:53 GMT150
In 1905 Einstein was a high school graduate waiting to get into a
higher level school. As such, he knew how to do algebra; but not how
to do calculus. When I began to study his paper, that was my level
too.
DARK FLOW and HUBBLE REDSHIFT are not contradicting each other IF.06 Oct 2008 09:02 GMT1
DARK FLOW and HUBBLE REDSHIFT are not contradicting each other IF.
See for the NASA article on dark flow:

HAARP06 Oct 2008 05:50 GMT16
Hi Ng
what do you think this HAARP machine in Alaska actually does?
There are theories, it is based on what is called Tesla waves and could send
powerfull pulses right through the earth.
The missing time NOT Stored?05 Oct 2008 16:18 GMT4
The scientists around here tell us that time flows at same rate,
no matter the reference frame.
So no time missed !!!
But still time is obviously conserved, because when the tween comes
