LIGO Gravitational Wave Observatory

Apr 1, 2009 - I am a naive..But let me ask .. Is LIGO able to filter the disturbances from seismic waves?.Coz the shock waves coming from an earth quake can also cause some change in distance(very very fractional) between the two mirrors???

VirtRampage Says:

May 23, 2009 - ok so you prove that there are gravitational waves, so what?

Thymonico Says:

May 24, 2009 - Science prevails! :D That, and we could possibly use these waves as a tool to communicate and send information. We'd want to use GWs because they won't get distorted by anything else.

akranis Says:

May 29, 2009 - That is why there are two of them. Even if the quake could reach both of them, they'd be out of sync with each others. They're only looking for data that looks exactly the same at both labs.

May 29, 2009 - Thanks for the reply !!!

Jun 27, 2009 - So What! If you prove there are gravity waves then scientist can track the earliest gravity wave from within 1 trillionith of a second after the big bang therefore going that early in time we can discover the source,creation, and meaning of life itself this should excite you like it excites me

Jul 24, 2009 - Telsa discovered these waves back in 1898. Standing Columar Waves,Terrestrial Stationary Waves,Tesla Waves,Phi Waves,Scalar Waves are all the same thing with different name. Tom Beardon and Dan Winter are the Telsas' and Heavisides of our time. These Scientist in this video use RENORMALIZATION on all there mathmatical hypothesis.

Jul 31, 2009 - Yes, they have to filter stuff happening all around the world, as its very sensative. It picks up sounds as quiet as peopels alarm clocks every morning, they have to filter out everything. The most effective LIGO would be a space observatory.

Aug 4, 2009 - Its running more than 5 years and hasn't detected anything. Because light does not travel any faster through contracted space as it would through expanded space (or our frame). If your meter stick is length contracted due to acceleration, light would not reach the end of the stick more quickly... Right?! Putting one of these in outer space would likely get the same result. Thus, it would be a waste of resources. Ligo and similar experiments need to be retired for now...

Sep 3, 2009 - Uhh ... the current version of LIGO is a proof of principle, and it was not expected to detect gravitational waves. If the next generation of LIGO doesn't detect anything, that would be surprising. As for your argument that light does not travel any faster through contracted space, that is true in one frame from which you can analyze the system. In that frame, however, the frequency of the light changes. I suggest you do the math before you decide whether there is a measurable effect or not.

ewmegoolies Says:

Sep 24, 2009 - Unless, LIGO predicts we live in a holographic universe, the only math needed for this project is an accountant to figure how much money has been wasted. I suggest somebody do the math quickly.

wganderson Says:

Sep 25, 2009 - So, publish your paper on the fundamental flaw of using a Fabry-Perot interferometer to measure gravitational waves is fundamentally flawed in a reputable peer-reviewed physics journal and show us all to be wrong. I guarantee I'll read it. Or are you just another crackpot who thinks that having an opinion is the same as doing physics?

wganderson Says:

Sep 25, 2009 - What? Of course we can tell the direction that a gravitational wave came from, provided we have at least three non-colocated interferometers to work with (currently there are five operating). And there is a lot that we will be able to say about the universe from gravitational wave observations - it will inform population models, reveal the structure of spacetime around black holes, and give important information about the composition of neutron stars, among other things.

cobrachoppergirl Says:

Sep 25, 2009 - So if you know the structure of spacetime around a black hole and something more about netron stars, what good will that do you? Like the guy said, you can't feed people with that. If you know a star far away is purple rather than green, yes you know something more about the universe, but was it worth spending millions to find out? And yes, the military is an even huger waste of money, which besides killing people, often drives science to find new and more devilish ways of killing people.

wganderson Says:

Sep 25, 2009 - So your position is that pure science (as opposed to applied science) is a waste of money? That is a tempting argument ,but it is short-sighted. Pure research gives applied research tools to work with, and it does so in unexpected ways. Who knew over 100 years ago when Planck postulated that light comes in quanta that it would lead to microprocessors, lasers, etc that have saved millions of lives? Also, are you opposed to spending on the arts? After all, you can't feed people music or paintings.

ewmegoolies Says:

Sep 25, 2009 - So, now everybody that has an opinion and doesn't publish a paper is a crackpot? Is that code word for squander a bunch of your own time before you take away our funding? What have you published to support this "proof of principle" as valid or validated?

etiennealive Says:

Oct 3, 2009 - In the Netherlands they are constructing an underground placed coper bol with a large diameter to detect gravitational waves. What do you think of this concept.? (they expect the bol to vibrate).

jingling30 Says:

Oct 6, 2009 - I think they should be putting more efforts in colliders to confirm supersymmetry to further develop string theory.

ehswan Says:

Oct 9, 2009 - A little thought experiment here. Suppose that gravity propagates at INFINITE velocity! How could an infinitesimal period of time be measured? Answer: no way! You all, by your absurd presumption, in my opinion, are DOOMED to FAIL Ha Ha .

ehswan Says:

Oct 9, 2009 - What is most essential at this time is to determine the velocity of the propagation of gravity. Finite or infinite? That is the question. If it is finite we are doomed to live in our little room, if infinite then we can visit our neighbors, and they can visit us.

sean6006 Says:

Oct 13, 2009 - Actually, I think that gravity waves (or the 'graviton') travel at at the speed of light, so to say that if the sun were to suddenly vanish it would take ~8 min for the earth to go off into space on a tangent. Also, can't we prove that gravity is a wave by observing gravitational interference? or by cancelling gravitational waves? Or shouldn't we be able to observe a doppler effect from distant galaxies? There are so many things to consider: What would be the frequency? My head is exploding...

Nov 9, 2009 - Gravity and or ghravity waves havebnyet been detected. In space matter is warping dark matter. On earth..gravity is the energy action between two objects...one being the planet. SUPERTELLIC UNIVERSE...
