Your free twice-weekly fix of stories of space and science –a random journey from Planet Earth through the Cosmos– that has the capacity to provide clues to our existence and add a much needed cosmic perspective in our Anthropocene epoch.
“It is possible that there’s a zoo of different compact objects, and while some of them are the black holes that follow Einstein and Hawking’s laws, others may be slightly different beasts,” says Maximiliano Isi, a NASA Einstein Postdoctoral Fellow in MIT’s Kavli Institute for Astrophysics and Space Research and lead author of a study about a signal from a gravitational wave merger.
This week’s newsletter covers news reports from “Why aren’t we talking more about UFOs?” asks Megan McArdle in the Washington Post to the first matter in the universe may have been a perfect liquid to the Milky Way’s supermassive black hole, Sagittarius A*, may actually be a colossal glob of dark matter.
“It is undeniable that we are profoundly puzzled, especially when it comes to the first fraction of a second that followed the Big Bang,” wrote theoretical physicist Dan Hooper, author of The Edge of Time in an email to The Daily Galaxy–Great Discoveries Channel. “I have no doubt that these earliest moments hold incredible secrets, but our universe holds its secrets closely. It is up to us to coax those secrets from its grip, transforming them from mystery into discovery.”
“Planet Earth Report” provides descriptive links to headline news by leading science journalists about the extraordinary discoveries, technology, people, and events changing our knowledge of Planet Earth and the future of the human species.
Albert Einstein was fond of saying that “Imagination is everything. It is the preview of life’s coming attractions.” What if our world, our universe, following Einstein’s insight, is the result of a quantum-physics experiment performed by some ancient hyper-advanced alien civilization. A civilization that, as astrophysicist Paul Davies speculates, may exist beyond matter.
