Just curious...have the physicists posited a frequency/wavelength for gravity waves? My little bit of inteference is so far all about amplitude of the gravity waves.

My guess would be that this is contingent on the motion of their source(s). Additionally, the frequency would be impacted by the motion of the receiver.


I found this site which you may enjoy:

5. What form does a gravitational-wave pulsar signal take at an Earth-based detector?



EDIT:

I kept reading.

3. What is the purpose of Einstein@Home?
Quote:
Einstein@Home is a method to search for gravitational waves from very dense, rapidly-spinning stars, such as neutron or quark stars [11,12,13]. The frequency of the waves is typically twice the star's spin frequency, though other frequencies are also possible. Thus, if the star is spinning about its axis 100 times per second, we might expect gravitational waves to be emitted primarily at a frequency of 200 cycles per second (Hz).

Fascinating! So it seems the gravity waves are frequency modulated by spin. The articles don't mention the mass of the stars, but in my model here the mass of a star or any body emanating gravity waves, amplitude modulates those waves. Spin =FM; mass = AM With a range of wavelengths to work with now, maybe we can make some interesting speculations about what gravity waves interference patterns might look like.

For the dark-matter-isn't-matter-it's-intefering-gravity-waves-from-matter proposition, this new info only makes the possible number of types of inteference patterns all the greater. Some you can surf...some not so much.

Fascinating...

Arrow Re: wave goodbye to dark matter

going with the general rule of a stars gravity wave frequency is twice its rate of spin-per-second, what is the wavelength of the gravity waves from our Sun?

1 rotation per 27 days
60*60*24=86,400 seconds per day
86,400*27= 2,332,800 seconds per rotation
1/2,332,800 = .000000428 rotations per second
multiply by 2 = .000000856 = Sun's gravity wave frequency

plug .000000856 into handy-dandy frequency-to-wavelength calculator >> Frequency Wavelength Calculator

result; wavelength of Sun's gravity waves = 350467289719626.1 meters (350467289719.6261 kilometers; 210,280,373,831.77566 miles)

yes/no?

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

We have been online since May 2000, and aim to be the best place to find and share science-related content of all kinds.
