I think so.They come from very very deep space.However micro waves that came out of the BB must be looked into.Being call Micro would not fit.Space could ripple waves from one end of universe to the other.When broken the effect could be instantanious.Bert

No!! As the frequency gets higher, the wave length gets shorter!!
Mains Power wave (50Hz or so) are about 6,000kms/3,500miles long.
Audio Freqs of, say 1kHz, are 300km/200miles long.
HF Radio wave, say 1MHz, are 300mtrs/0.2miles long.
FM radio stations (approx 100MHz) have a 3mtr/10foot long wavelength.
Microwave frequencies, say 3GHz, have a wavelength of 100mm/4 inches long!


Hmmm 4 inches and still called a "Micro .Radio waves can be 2 miles long(read that Hmmm) Waves that interfere must really spread out?? Does gravity curve every type of wave? Bert

4 inches is a heck of a lot shorter than some radio wavelengths!! No
need for "Hmm". LF (Low Frequency) Band - 30kHz to 300kHz, wavelength
10km/6miles to 1km/0.6miles.

Radio waves can be diffracted with-in the Earth's Atmosphere by near
contact with Hills/Mountains, so I would expect gravity to curve light
.... come to think of it, in (real) Astronomy, they talk about objects
(stars, nebulas, etc) bending light waves as the waves pass by the
objects. This process is known as "Lensing" presumably because it tends
to focus the waveform.
