Sams softening up the ground for an announcement that some sort of
anomaly has been observed but not what they predicted. By posting this
article in this thread *before* the results are announced...Sam et al
are hoping it will look like they predicted, a priori, that the gravitational
*waves* wont look like what they initially predicted.
Now when the results are announced Sam et al can say...." Look!...
we did actually predict they would look different to what we expected"

I posted my thoughts that close to the universe's horizen "GRAVITY FLIPS" and thus is expanding space at an accelerating rate. Locally gravity is an inward force.22 billion LYs out it becomes an outward force. TreBert

Dark Matter!
Haw.

Some idiots thought that if the outer stars
of galaxies had mass around the galaxy
to pull on them as they were
coming around, that could explain why
they go faster than they should, and they
ran with that idea.
Forgetting that as soon as the star goes
past, it will be decelerated by exactly that
same amount.

John have you ever studied orbital mechanics?

Actually, I withdraw the question. Obviously the answer is no.

But here is something for you to think about.... When we launch a deep space probe we always use planetary bodies and their gravity wells to get a 'free' speed boost.

But according to what your said above, this would be impossible since all that speed would be lost
as the craft rounded the planet.

If this is beyond you, ask Mr Bodkin or professor Wormley to explain in a more teacher-like manner

Which part of Orbital Mechanics do you need explained to you HVAC?

You quoted free as 'free' for there is no Free Launch. Right?! (TM)

Fwiw, Galactic Dynamics is a bit different than Orbital Mechanics.

I put the quotes around 'free' to indicate that all physical laws apply. Energy can never be created nor destroyed in our universe.

I bet you HVAC are as stupid in person as you are in writing.

I know what information and actions of USA citizens are legally
classified. Your response is a bonafide non-sequiter. As usual.

The First Law of Thermodynamics. I've never heard, read, or thought

How does a star "go past" a dark matter distribution that is spread
evenly around the circumference of the galaxy?

As for decelerating the same amount, I had assumed you knew about the
slingshot maneuver, where a deep space probe is sent near a planet like
Jupiter and Saturn to speed its travel to the outer reaches of the solar
system. Not temporarily speed it up. Permanently speed it up. According
to you, this can't happen, but it's been done. Explain.

It can work if everything is immersed
in Dark Matter (like in an ocean),
and the DM, itself, is in a whirlpool
configuration.
