Hydrogen indigestion

LIGO was $600 million, all the science preceding effectively priceless, what's one more nail in the coffin experiment? What if it discovers something slightly different, or wholly unexpected, it's a new test never done before. It also would appeal to many of the public who fund a great deal of scien...

I understand your curiosity, but unlike "direct" gravitational wave detection, the result would neither be exciting nor a surprise. By the way, clock synchronization is a big problem. How does one know how long the one-way time is? The historical measurement of c by the delay in Jupiter's...

I think it's still worth one test of possibly the most direct validation of a fundamental property of relativity. From what I've found, believe it or not, it hasn't been directly tested. I'd really like to be shown otherwise for at least myself. Regarding interferometry, there's more than one way to...

I don't believe anyone's ever directly tested the one-way speed of light anisotropy in a vacuum. I think it's always done with interferometry, using properties of light to measure light, a seemingly bad idea. When that's tested, I'll be a believer in Einstein's magic. The thing is, it can be measure...

Looking at your gamma ray image with the note that they eminate from black hole accretion disks, it makes it look like our galaxy is loaded with black holes.

It might take that third detector and more sensitivity to locate and observe ahead of time the pending closure before the final event, and get some nice astrovideography to accompany the gravity waves. How much advance notice are we likely to get of these events. ? There is no indication that gravi...

Chris, maybe it's possible that the presented visual model might actually be viewable? Suppose with some fortune a bright distant galaxy lies behind the event with enough intensity to see from Earth. You might just pick out some of that modulation. It might take that third detector and more sensitiv...

I wonder what Mars smells like... With all the great imagery that NASA/JPL/Hollywood/etc. has provided us, I still wonder how it would truly "feel" - standing on the gritty untouched rusty surface. That material inevitably gets inside your suit.

That's great.

Stock owners of Reynolds Wrap should be happy too.

I followed up with my own suggestion and created an audio file that pulled in the strain plot on page 10 of their report at https://dcc.ligo.org/LIGO-P1500218/public/main I don't know where there's a safe place to upload & share files these days, but you can listen here https://clyp.it/wcbp3v1s ...

Three detectors would also allow "imaging" in the same way that three radio telescopes do. In fact, even with the LIGO data it is possible to produce a sort of low resolution image. I'm thinking that radio telescopes can image because of the wide angular span of their objects of interest....

I'm curious, I know that the gravitational waves produced by this are infinitesimally small by the time they reach Earth but would they be strong enough for a human to feel them if you were close enough to the black holes (and assuming you wouldn't be fired by radiation etc...)? I'll just make an o...

Does a merge mean they fall within each other's event horizon? I thought they were infinitesimally small, so do they ever fully merge? I wonder how far away the viewer is in the video.

I see. Thank you. So, I suppose you effectively point/focus by adjusting the lag times on all the detectors, when you combine all their signals together. I bet you're right, two detectors should define the cone where the merger occurred on, three should form a direction, and three way out in space ...

like the title's metaphor

Maybe not the initial onslaught of radiation, we need a supernova duck & cover red alert system...

Thanks!

Given what looks like 5 prior generations, I'd be questioning those old theories myself.

I wonder what's the latest theory as to why gravity waves have been so hard to detect.

I see Mickey Mouse on the Moon more easily, although the orientation of the APOD doesn't resemble it

Has anyone ever raced out toward the poles after hearing about a coronal mass ejection? Looked like you have 13 hours to many days to get there, if you learned about it right away and that it was heading to Earth.

Unmatched in filmmaking even

Very interesting but possibly a bit too controversial to extrapolate to the expansion of the universe

Amen!
