This is the best "general public" article I've read so far:

LIGO’s ultra-high-vacuum hermetic perfection, Márka quips, is “the most expensive ‘nothing’ ever made.”

An amazing feat of technology. What good does it do? Would you invest in this research, personally? Should we be investing tax dollars in this? What can we do with the knowledge we get?

I am not in favor of the feds "investing" my money in anything. But if I had to choose, I take this over social services any day.

I've always admired practical people... but fundamental science needs to go on, whether it has an immediate application or not. What is being done right now, is that we're sowing the seeds of humanity's future. If this eventually results into something practical remains yet to be seen. But research cannot ever stop, or humanity will grind to a halt.

What good, may I ask, has ever come out of studying places like Saturn's moon, Titan, or even placing a man on the moon?
I say that those sort of ventures are pretty much like climbing a mountain, we do it because we find ourselves challenged. "Because it's there", as George Mallory once famously said. And besides, we learn lots of new things in the process that can be (and have been) applied to practical things in our daily lives.

Trust me, great good will come out of this research. Maybe not in our lifetimes, or even in those of our children's children's children. What's important is that we keep learning. Many people thought that the work of Einstein, or Maxwell, or even the field of quantum physics would never reap any benefits for humanity. And see what happened.

Yes, countless times I've heard the "children are starving" and "those founds would've been better spent doing medical research" sort of argument. And those are valid arguments. But we cannot focus our sight so tight that we ignore every other field of science, simply because we never know where it might lead us. It's all a matter of balance, I say.

Well, it does help keep the rich white folk suitably employed. It keeps the high-profit industries busy. It is good for the economy. All those billions are spent here at home (aren't they?)

My question about mass capacity is whether a black hole can reach a limit where it becomes unstable and it may disintegrate.

Not by a generally accepted theory. Blackholes present a challenge to more understanding of the universe. For example, do blackholes preserve information? Is quantum entanglement valid in the blackhole?

A similar question can be asked about the original object that produced the big bang. What was there before the bang and why was it stabile up until it exploded.

The equivalent of it is the whitehole. We simply do not have a sense, and may never have a sense, about what caused the big bang, or "time before the big bang" - in the post-big bang physics, that question does not make sense.

It would be conceivable to think that at least some information is preserved "through" the big bang. ie. at least part of our world carries information about the "pre-big bang world".

 

The speed of gravitational waves is exceeded only by the speed of the willing suspension of disbelief.

Wow... it's been years since I've had to use a fourier transform ... if only I had the time to sift through all that info and get a deeper understanding...

 

My predictions on gravitational waves.
Faraday predicted EM waves in the 18th century. Look where we are.
Einstein predicted gravitational waves, they've now been discovered. Give it a century or two for the engineering pioneers to come along and we'll be living in a sci-fi world my friends.

That would be Maxwell not Faraday for EM waves. Other than being an eye to the universe with passive receivers I can't see human manipulation of gravitational waves until we are much higher on the Kardashev scale.

 

Wrong. Faraday predicted EM waves. Maxwell proved it with his maths.
I welcome abstract thought. Picture yourself walking the Alps in order to invade Rome alongside Hannibal and you look up to the stars and notice the moon. It would be absurd to conceive such a thought of man walking on such a distant object.... but we did it.
We are now in a new era. A century from now this lifestyle will be obsolete.

 

Truth being told, I was more impressed with the discovery of the higgs boson than with GW...
I mean, sure they're a cool thing to have discovered and confirmed, but maybe their practical applications are quite limited compared to the HB...

Both were great men but in science Prediction is not just thinking something can exist, prediction is the ability to model the future behavior of physical systems like Einstein did with gravitational waves. The scientific prediction of Maxwell's (Gauss, Faraday,Maxwell's addition to Ampère) electromagnetic wave equation from his coherent theory of electromagnetism led directly to the Einstein scientific prediction of the waveform we saw with the LIGO detection.

 

Why is this so profound? There is gravity between objects. Of course there should be gravity waves? Is the artist's rendering just the artist's view of these waves? Do gamma rays travel at the same speed as light and gravity? They are electromagnetic just really short wavelength? (a question)
We spent over a billion dollars on this? No wonder the nation is going broke. It seems like a waste of money and brain power. Aren't there more important questions to answer that have a real effect on our lives?

sry for late replying because of network problem . Your question is true. But its needed to us. There are so many superstation on earth. If we solve this mystry we can eradicate the wrong thoughts from the people's mind . You are so kind to people. So you are asking this question. But understand them. And let's do them their work. We have to know more about this beautiful world.we can solve many questions after solving ths mystery.

 

I really hope this is not just some statistically improbable fluctuation.

 

Hoax, the Hubble telescope cannot see the lunar lander. SO how can the Hubble see a black hole that has the diameter of the Sun but 1.5 light years from the earth. You cannot not just believe these people. You have to check their numbers! And the force will be with you. nano, nano by nanospook.

These alternative models deny the possibility of event horizons—the no-exit boundaries that define black holes. However, compact objects within these models would still have a light ring—the relativistic boundary within which photons can be trapped in circular orbits. Cardoso and his colleagues calculated the ringdown phase from a generic horizonless compact object. They modeled the light ring around this black hole mimicker using a wormhole, which is a double-funnel warping of spacetime. The results showed that the mimicker’s gravitational waves are nearly indistinguishable from the black hole case, up until the end when the two signals diverge. Unfortunately, LIGO’s data from September 2015 falls off before this divergence, so louder events or more sensitive detectors will be needed to determine whether ringdown behavior confirms black holes.

The gravitational waves detected might just be spaceships jumping into wormholes.

is this a perfect shape? Gravitational force is acting around every massive object. Means every point of massive object Explose gravitons.

 

What is the force called that can separate the gravity field from it's source at the velocity of c?

If it's angular momentum, then mass can travel at c.

Wave velocity is equal to angular velocity.

Why, after emission and during flight, does the wave not attract and gather matter? Or at least a wake.

The detected wave had a up chirp. An up chirp indicates absorption. A down chirp indicates emission.

I would be looking at platonic plate movement. Something was absorbed.
