This morning leaders of the Laser Interferometer Gravitational Wave Observatory (LIGO) announced the first direct detection of gravitational waves. In honor of this momentous discovery, the Perimeter Institute in Waterloo, Ontario, is hosting a live webcast today at 1pm EST: “Ripple Effects: A Forum on Gravitational Waves.”

もみじまんじゅう Did you know that LIGO system is receiving signals that number in the hundreds and they classify them as “glitches” ! And Scientist have no idea the sources of these so-called glitches. Could it be that this GW chirp is actually just a glitch which are misinterpreted to be a gravitational waves. Please note the excerpts of the article which follows; *LIGO glitches are detector events of unknown origin whose frequency spectrum does not look like the expected gravitational wave signals. I don’t know exactly how many of those the detector suffers from, but the way they are numbered, by a date and two digits, indicates between 10 and 100 a day. LIGO uses a citizen science project, called “Gravity Spy” to identify glitches. There isn’t one type of glitch, there are many different types of them, with names like “Koi fish,” “whistle,” or “blip.” In the figures below you see a few examples.* And here’s another example of an article relating to the blips; *Blip glitches are short noise transients present in data from ground-based gravitational-wave observatories. These glitches resemble the gravitational-wave signature of massive binary black hole mergers. Hence, the sensitivity of transient gravitational-wave searches to such high-mass systems and other potential short duration sources is degraded by the presence of blip glitches. The origin and rate of occurrence of this type of glitch have been largely unknown.* This is going to be the biggest debacle in scientific history, and I must say, a well deserve one!

I'm not sure anyone knows how many stars there are in the universe. Kip didn't bother to make it clear whether he meant fifty time greater than all the stars in the universe for those few milliseconds or fifty times greater than all the stars in the universe since the beginning of time. But when nobody on the panel objected when Reize told us _twice_ that Alpha Centauri is three and a quarter light years away I get the feeling LIGO's much-touted precision is not particularly high on their agenda. Nevertheless it all sounds pretty impressive, eh what? .

If we now look for LIGO signals from the regions of space occupied by the distant galaxies that Hubble showed are accelerating away, would we expect to see the strength of the gravitational waves of equivalent size black hole collisions being dramatically or completely reduced to nothing due to the possible expansion of space time?

I have a question, being that the LIGO system is picking up many glitches and some of them look like gravitational waves, how certain are you that your interpretation is the right one, considering these anomalies? In other words, is it a Possible that you are inadvertently cherry picking the data? See this; *”Blip glitches are short noise transients present in data from ground-based gravitational-wave observatories. These glitches resemble the gravitational-wave signature of massive binary black hole mergers. Hence, the sensitivity of transient gravitational-wave searches to such high-mass systems and other potential short duration sources is degraded by the presence of blip glitches. The origin and rate of occurrence of this type of glitch have been largely unknown. In this paper we explore the population of blip glitches in Advanced LIGO during its first and second observing runs. On average, we find that Advanced LIGO data contains approximately two blip glitches per hour of data. We identify four subsets of blip glitches correlated with detector auxiliary or environmental sensor channels, however the physical causes of the majority of blips remain unclear.”* Is the LIGO consortium a exercise in confirmation bias?

Since gravitational waves are limited to the speed of light, how is it theoretically possible to move faster than the speed of light using a Alcubierre Warp Drive?
@jmckenna123
@jmckenna123 8 лет назад
Because the warp drive theory does not exceed light speed. Theoretically a warp drive compresses the empty space between you and your destination. Think of a 10 foot carpeted room. At one foot per second it would take you 10 seconds to cross the carpet. A warp drive would effectively roll up the carpet in front of you so the other side is only a foot away. You travel the same speed, but cross the carpet in one second, not ten. That's warp drive theory!

@sisu9663
@sisu9663 5 лет назад
After the merger, the gravitational wave is attenuated to well below noise threshold. It is not still emitting gravitational waves because it is now a single rotating black hole. The fact that we have detected this signal is a mix of luck and frequency. It suggests that black holes are a lot more numerous than previously estimated. Hope this helps
