Why is it that we can see these multiple histories play out on the quantum scale, and why do lose sight of them on our macroscopic scale? Many physicists believe that the answer lies in a process known as quantum decoherence.

The plan: launch a giant fleet of tiny spacecraft with powerful lasers and see where gravity drags them.
The U.S. space agency National Aeronautics Space Administration (NASA), European Space Agency (ESA), and Japan Aerospace Exploration Agency (JAXA) are inviting coders, entrepreneurs, scientists, designers, storytellers, makers, builders, artists, and technologists to participate in a virtual hackathon May 30–31 dedicated to putting open data to work in developing solutions to issues related to the COVID-19 pandemic.
During the global Space Apps COVID-19 Challenge, participants from around the world will create virtual teams that – during a 48-hour period – will use Earth observation data to propose solutions to COVID-19-related challenges ranging from studying the coronavirus that causes COVID-19 and its spread to the impact the disease is having on the Earth system. Registration for this challenge opens in mid-May.
“There’s a tremendous need for our collective ingenuity right now,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate. “I can’t imagine a more worthy focus than COVID-19 on which to direct the energy and enthusiasm from around the world with the Space Apps Challenge that always generates such amazing solutions.”
The unique capabilities of NASA and its partner space agencies in the areas of science and technology enable them to lend a hand during this global crisis. Since the start of the global outbreak, Earth science specialists from each agency have been exploring ways to use unique Earth observation data to aid understanding of the interplay of the Earth system – on global to local scales – with aspects of the COVID-19 outbreak, including, potentially, our ability to combat it. The hackathon will also examine the human and economic response to the virus.

Special Relativity. It’s been the bane of space explorers, futurists and science fiction authors since Albert Einstein first proposed it in 1905. For those of us who dream of humans one-day becoming an interstellar species, this scientific fact is like a wet blanket.

Astronomy & Astrophysics (A&A) is an international journal which publishes papers on all aspects of astronomy and astrophysics.
The closest black hole to the Earth has been discovered just 1,000 light years away — near enough to see its companion stars with the naked eye on a clear night.
Located in the constellation of Telescopium, the hole forms part of a so-called ‘triple system — one named ‘HR 6819’ — with its two accompanying stars.

A wormhole with a long, thin throat could prop itself open long enough to let through pulses of light, offering a way to talk across time.
How can a Big Bang have been the start of the universe, since intense explosions destroy everything? – Tristan S., age 8, Newark, Delaware.
Bochum cosmologists headed by Professor Hendrik Hildebrandt have gained new insights into the density and structure of matter in the universe. Several years ago, Hildebrandt had already been involved in a research consortium that had pointed out discrepancies in the data between different groups. The values determined for matter density and structure differed depending on the measurement method. A new analysis, which included additional infrared data, made the differences stand out even more. They could indicate that this is the flaw in the Standard Model of Cosmology.
Rubin, the science magazine of Ruhr-Universität Bochum, has published a report on Hendrik Hildebrandt’s research. The latest analysis of the research consortium, called Kilo-Degree Survey, was published in the journal Astronomy and Astrophysics in January 2020.
