LISA, the Gravitational Wave Hunter, Canceled : Discovery News
"April is proving to be the cruelest month for the Laser Interferometer
Space Antenna (LISA), a major space mission to look for gravitational
waves that was slated for launch around 2015. But news broke this week
that NASA is abandoning funding for the project, which means the U.S.
will cede its role in developing this critical instrument in order to
redirect funds to the James Webb Space Telescope (JWST). Sure, money is
tight these days, and we need a replacement for the aging Hubble Space
Telescope. It's still a sad, sad day for physics."

It is a GREAT day for science, and a bad day for physicks.
It must have dawned on those who count the beans that looking for elves
or Elvis, or gravitational waves, is an eternal money sink.
I am relieved, at least that nonsense ends.
Einstein is dead, his failed theories should be put to rest too.
So that we can move on.

You won't be happy until the American science budget is zeroed out.
You must vote straight republican.

These waves were first predicted by Einstein's general theory of
relativity in 1916. At the time, we didn't have the technology to detect
them, since they are very weak and fade very quickly, although
scientists found indirect evidence of their existence in observations of
a binary pulsar -- work that won the Nobel Prize in physics in 1993. But
now we have the technology, and these gravitational waves should be
detectable with very sensitive instruments.

One of these instruments is already up and running: the Laser
Interferometer Gravitational Observatory (LIGO). As its name implies,
LIGO is essentially a giant interferometer. There is a very large mirror
hung in such a way as to form an arm, with two more mirrors hung
perpendicular to it to form an L-shape. Scientists then pass laser light
through a beam splitter, thereby dividing the beam between those two
arms, and let the light bounce back and forth a few times before
returning to the beam splitter.

LIGO has three such detectors, since it needs to operate at least two
detectors at the same time as a control, so they don't get false
positives. A passing gravity wave will cause ripples in space-time,
which in turn will change the distance measured by a light beam; the
amount of light falling on the strategically placed photodetector will
vary slightly in response. The resulting signal will tell scientists how
the light hitting the photodetector changes over time.

Too bad LISA is not proceeding at this time of great human exploration.

If we didn't find it with our ground-based instruments, how likely were
we to find it with space-based ones?

Did you look to see the sensitivity differences between the two
instruments and noise sources for each?

Apparently it never crossed your mind that the two instruments would
be different.

Suck gravity makes no sense.
It has never made sense.
It will never make sense.

It predicts black holes- singularities- which
are obviously nonsensical.

Do you believe in fairies, Eric?

They make more sense.

Give up on physics, Eric.
Take up rain-dancing, or voodoo, or reading palms.

They make more sense.

Nothing science does makes sense to you. You have no education in the
subject. Your opinions are of concern to literally nobody.

Yea, we all know that.

You should, just to keep the perspective right, ALSO mention that Einstein HIMSELF,
at the end of his life, admitted he failed to come up with a theory that connected gravity with the other forces.
In that light a 1916 IDEA that is in NO WAY confirmed (capslock came free with the keyboard, although I could do without it)
is not worth pursuing to the extreme of extremes.
Apart from the technological problems to couple a bunch of satellites with lasers over such long distances,
remember how gravity probe B after 25 years of 'design and improvement' failed in implementing simple mechanics,
we KNOW ***LIGO*** sees nothing. Neither did Michelson Morley (sort of a small version of LIGO),
and neither did any of the other more crude experiments in the past, all of those based on 'simple relativity calculations'.
In spite of the fact that according to Einstein's relativity calculations LIGO should have seen a signal in its first incarnation.
So OBVIOUSLY we should be asking 'why no signal', and NOT how to make it ever more sensitive.
Maybe those scientists say they are atheists, but it seems to me they DO have a religion,
they believe in Einstein.
How sad, Einstein did not even believe in himself, his own theories, as he stated many times they are build on the quicksand
of assumptions, lightspeed being c one of those. No proof, just dogma, that is where religions start.
That is also what kept the sun orbiting the earth so many years, and the earth flat on top of that (pun not intended).
Earth flat under that? well whatever.
So, current generation of brain dead mathematicians (and half body dead too), will protect their status as the geniuses of our time,
writing books on the 'origin of time' and what not, with an authority no better then Aristotle's about chemistry.
So in hundreds of years, given that humanity still exists and not just mosquitos rule the earth,
when these generations of fake math spitting formula jinglers are dead,
their children they brainwashed with their crap too,
and a person will stand up, point out the emperors clothes are missing,
and come up with a logical explanation, probably one that has been mentioned here many times,
and we can travel to the stars. Until then science is dead.
