Today Mars is a frigid desert world with a carbon dioxide atmosphere 100 times thinner than Earth’s, the result of red planet’s protective magnetic field switching off half a billion years ago. NASA scientists speculate that an impact basin deep enough to swallow Mount Everest in Valles Marineris highlights what might be the results of a ancient asteroid collision that switched off Mars magnetic field, bathing the planet in deadly radiation, and eroding its atmosphere by particles streaming from solar winds.
Astronomers are targeting the radio frequency range between 4 and 8 gigahertz, dubbed the C-band, said Breakthrough Listen principal investigator, astrophysicist Andrew Siemion of the University of California, Berkeley, who announced the release of nearly 2 petabytes of data, the most comprehensive survey yet of radio emissions from the plane of the Milky Way Galaxy and the region around its central black hole, the second data dump from the four-year old search for extraterrestrial intelligence (SETI).
“If our universe is just one of an infinite number, then once inflation stopped in ours, pockets within it that had been inflating would have then collapsed into black holes. The longer each pocket inflated, the more massive the black hole,” suggested Alexander Vilenkin, professor of physics and director of the Institute of Cosmology at Tufts University and author of Many Worlds in One: The Search for Other Universes.
“For a long time, scientists were really focused on finding sun- and Earth-like systems. That’s all we knew. But we found out that there’s this whole crazy diversity in planets. We found planets as small as the moon. We found giant planets. And we found some that orbit tiny stars, giant stars and multiple stars,” said Elisa Quintana, a NASA Goddard astrophysicist who led the 2014 discovery of Earth-sized planet Kepler-186f about the use of NASA’s Discover supercomputer to determine whether any of more than 4,000 distinctly strange exoplanets discovered in the past two decades could support life.
God-like beings will exist in the future, and they may be able to affect their past — our present — by means of spacetime engineering. Probably other civilizations out there, perhaps millions to billions of years older than Earth’s, have already attained God-like powers, says Giulio Prisco. a technology expert, futurist and author of Tales of the Turing Church, who believes that the ‘manifest destiny’ of our species is colonizing the universe and developing spacetime engineering and scientific “future magic” much beyond our current understanding and imagination.
Scientists have yet to crack the enduring mystery of dark matter, but conjectures vary from suggesting that it may be older than the Big Bang to particles the size of galaxies to highly-speculative dark-matter life, consistent with the known laws of the universe. Now, researchers from the Universities of Bonn and Strasbourg have simulated the formation of galaxies in a universe without dark matter.
