F.A.Q about Experimental Tests Invalidating Einstein's Relativity
Marmet again
-
How accurate are the
measurements of the Sagnac effect?
A.
-
The
Sagnac
experiment has been measured a large number of times
during the last century. In the case of an experiment of radio waves
moving around the Earth, Michelson and Gale (Ref. Michelson A. and
Gale H. Astroph. J. 1925, 61, 137-145)
made the first observation that the electromagnetic signals around the
world took a different time in the East and West directions in 1925.
Very recently, using a ring laser, Bilger H. R. et al. (IEEE Trans. 44,
No:2, p. 468-470) confirmed that the Sagnac effect to better than one
part in 1020. -
Add Sticky NoteConsider
a
mass
standing
on the surface of the Earth. After one year,
the mass submitted to gravitational acceleration is always standing
there, without changing its energy or velocity. Let us also consider
another identical mass, submitted to an inertial acceleration of one G
in outer space due to the push of a rocket. After one year, the
enormous energy given to the mass is such that its velocity has reached
an important fraction of the velocity of light. If that mass falls on
Earth its energy produces a gigantic crater on the impact.- What on earth is Marmet trying to say? The mass in space has no equal and opposing force acting _on_it_. - on 2009-11-26

Alternative to big bang by Paul Marmet
At the beginning of time and the big bang, At what speed were the stars and planets thrown across the universe? - Yahoo! UK & Ireland Answers
-
The rate of this expansion is measured to be 71 km/s/Mpc.
-
if you're talking about the speed of the inflationary period as put forth by physicist Alan Guth, the universe expanded faster than light speed for a very brief fraction of a second, right at the beginning of time.

ESA Science & Technology: LISA
Experiment at the heart and the extremes of Einstein's general relativity
-
Add Sticky NoteIt follows that LISA becomes candidate for launch as an L-class mission concept of CV 2015-2025 with the earliest possible launch window in 2020.
- Will somebody else detect gravitational waves before this launches in 2020? - on 2009-11-09
-
When gravitational waves become observable they will provide a new and uniquely powerful probe of the extremes of spacetime, from the Big Bang to black holes, to address the deep questions that have emerged in Einstein's vision of the cosmos: what powered the Big Bang, what happens to space and time in black holes and what is the mysterious dark energy accelerating the expansion of the Universe?

Sounds good - didn't try it yet.

Once you save the file and run Stellarium, you should see Comet Lulin appear. Happy Comet watching!
Stellarium
This is a lovely new open source planetarium app, for Mac and Windows (and source for Linux). Once you realise there are 2 menus one on the lower left edge, and one on the left of the bottom edge, it is a dream to get started.

Stellarium is a free open source planetarium for your computer. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope.
Free Astronomy Software on Mac OS X - Installing KStars : Bart Busschots
This is a shame as it is a long download and install, and takes up a lot of hard disk space. However, kstars is a great sky map that works well on Linux, so it should be just as good on Mac.
Looks like a great install guide, and it sounds like an easy
-
However, if you run Mac OS X things have traditionally not been so good.
...
That leaves us with just KStars. ...

In our case, we know the proportion of the accelerations, different by 1.129 * 10-6 m/s2 /9.8 m/s2 so the left fraction is 1.0000001152. The radius R therefore has to be in the proportion of 1.0000000576 so that its square would be the acceleration proportion. If we multiply this proportion (difference) by the radius of the Earth, 6.378 * 106 meters, we get 0.367 meter, which is the required difference is Earth radius to account for the difference in the acceleration.
