Jackson,=C2=A0Gregory Benford(Submitted on 2 Jun 2018 (v1), last revi= sed 21 Jun 2018 (this version, v4)) We consider how an advanced civilization might build a radiator to send gra= vitational waves signals by using small black holes. Micro black holes on t= he scale of centimeters but with masses of asteroids to planets are manipul= ated with a super advanced instrumentality, possibly with very large electr= omagnetic fields. The machine envisioned emits gravitational waves in the G= Hz frequency range. If the source to receiver distance is a characteristic = length in the galaxy, up to 10000 light years, the masses involved are at l= east planetary in magnitude. To provide the energy for this system we posit= a very advanced civilization that has a Kerr black hole at its disposal an= d can extract energy by way of super-radiance. Background gravitational rad= iation sets a limit on the dimensionless amplitude that can be measured at = interstellar distance using a LIGO like detector. | Comments: | 19 pages | | Subjects: | Popular Physics (physics.pop-ph); General Relativity and Quan= tum Cosmology (gr-qc) | | Cite=C2=A0as: | arXiv:1806.02334=C2=A0[physics.pop-ph] | | =C2=A0 | (or=C2=A0arXiv:1806.02334v4=C2=A0[physics.pop-ph]=C2=A0for this = version) | ------=_Part_3396292_203627871.1536713611388 Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: quoted-printable <html><head></head><body><div style=3D"color:#000; background-color:#fff; f= ont-family:Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font= -size:13px"><h1 style=3D"margin-top: 0.5em; margin-bottom: 0.5em; margin-le= ft: 20px; font-size: x-large; line-height: 28.8px; font-family: "Lucid= a Grande", helvetica, arial, verdana, sans-serif;" id=3D"yui_3_16_0_ym= 19_1_1536361457536_379819">A Gravitational Wave Transmitter</h1><div style= =3D"margin: 0.5em 0px 0.5em 20px; font-size: medium; line-height: 24px; fon= t-family: "Lucida Grande", helvetica, arial, verdana, sans-serif;= " id=3D"yui_3_16_0_ym19_1_1536361457536_379820"><a href=3D"https://arxiv.or= g/search/physics?searchtype=3Dauthor&query=3DJackson%2C+A+A" style=3D"t= ext-decoration-line: none;" id=3D"yui_3_16_0_ym19_1_1536361457536_379821">A= .
