Team of physicists suggests LIGO could be used to detect giant alien spacecraft
A team of physicists affiliated with several institutions in the U.S. has collaborated on a paper that discusses the possibility of using the Laser Interferometer Gravitational Wave Observatory (LIGO) to search for evidence ...
Planetary scientists suggest a solution to the Fermi paradox: Superlinear scaling leading to a singularity
A pair of researchers, one with the Carnegie Institution for Science, the other with California Institute of Technology, has developed a possible solution to the Fermi Paradox. In their paper published in Journal of the Royal ...
If there are Dyson spheres around white dwarfs, we should be able to detect them
Searching for Dyson spheres, rings or swarms remains a preoccupation of many astronomers. If there are any out there, they will eventually be found, and the person or research team to do so will go down in history for making ...
