Roaming Goldilocks…

Topics: Astrophysics, Planetary Science, SETI, Space Exploration Even as a child, before he devoted his life to the search for extraterrestrial life, Frank Drake wondered whether Earth was alone in its ability to harbor life. He wasn’t the first or the only one to wonder. There’s a reason so many are fascinated by the question:Continue reading “Roaming Goldilocks…”

Flirting by Starlight…

Topics: Astrophysics, Electromagnetic Radiation, Entanglement, SETI When we gaze up at the night sky, we might be accidentally eavesdropping on an alien conversation. At least, that’s according to Imperial College London quantum physicist Terry Rudolph, who last week published preprint research theorizing that an advanced extraterrestrial civilization might alter the light coming off stars in order toContinue reading “Flirting by Starlight…”

Nano, to Planck…

Topics: Barrow Scale, Kardashev Scale, Exoplanets, SETI The Kardashev Scale is a discussion, and ranking of civilizations based on energy output: Type I: able to marshal energy resources for communications on a planet-wide scale, equivalent to the entire present power consumption of the human race, or about 1016 watts. Here, Carl Sagan begged to differ, due to powerContinue reading “Nano, to Planck…”

Adversary, Friendly, or Neutral…

Topics: Aerodynamics, Applied Physics, Biology, Exoplanets, General Relativity, SETI May 17, 2019- No, little green men aren’t likely after the conquest of humanity. Boyd’s piece for Phys.org highlights the reason why the Pentagon wants to identify UFOs: they’re unidentified. If a warfighter on the ground or in the sky can’t ID an object, that creates aContinue reading “Adversary, Friendly, or Neutral…”

Panspermia…

Topics: Astrobiology, Biology, Cosmology, SETI Life, for all its complexities, has a simple commonality: It spreads. Plants, animals, and bacteria have colonized almost every nook and cranny of our world. But why stop there? Some scientists speculate that biological matter may have proliferated across the cosmos itself, transported from planet to planet on wayward lumpsContinue reading “Panspermia…”

The Question is Moot…

Topics: Astrobiology, Astronomy, Astrophysics, SETI Cultural references: The post title refers to NC A&T Alumni, and Civil Rights icon Reverend Jesse Jackson’s appearance on Saturday Night Live, and the Wow! signal. Personal note: This signal appeared on the same day my granddaughter was born. On April 29, 2019, the Parkes Radio Telescope in Australia beganContinue reading “The Question is Moot…”
