“Wolf went for a walk over the world from the Mir Space Station in the late 1990s and saw the Earth seemingly vanish. His recollection so moved New York-based artist Rachel Rose when she heard it on NPR that she went to considerable lengths to track him down for a personal retelling.”

Get Ready To 3D Print Your Own Satellites In Space — By Neel V. Patel | Inverse

“A California startup called Made In Space wants to make 3D for use in orbit. The idea is to give consumers the opportunity to allow their own satellites to be built right there, several hundred miles above Earth’s surface. Plans are in motion to send up a printer capable of accepting printing instructions from the public and building whatever someone on the ground has in mind.”

How to plan the ultimate long-term project, from the team who got us to Pluto — By Daniel Terdiman | Fast Company

One thing you don’t expect when planning a nine-year mission to the most distant planet in our solar system is the eventuality that Pluto might not be a planet once you got there.

Yet that’s exactly what went down in 2006. That January, NASA launched its unmanned New Horizons probe, a baby grand piano-sized, 1,054-pound spacecraft, on the first-ever route to Pluto. Then, in August 2006, the International Astronomical Union demoted Pluto to the diminutive status of “dwarf planet.”

Universe might contain millions of black holes

Posted by in categories: astronomy, gravity, physics, space

Black holes are, by definition, impossible to see by conventional methods and are often further obscured by thick blankets of dust or gas. But that’s not an issue for NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR). It can peek through the obscuring layers and monitor the black holes via the high-energy X-rays that they emit. And, after a recent survey that spotted five previously unknown supermassive black holes in the centers of various galaxies, NASA researchers now think there could be millions of of them dotting the Universe like the holes of an intergalactic colander.

“Thanks to NuSTAR, for the first time, we have been able to clearly identify these hidden monsters that are predicted to be there, but have previously been elusive because of their surrounding cocoons of material,” said George Lansbury of Durham University in a statement. “Although we have only detected five of these hidden supermassive black holes, when we extrapolate our results across the whole universe, then the predicted numbers are huge and in agreement with what we would expect to see.” The team’s research has been accepted for publication in The Astrophysical Journal.

Strings Are Dead

Posted by in categories: anti-gravity, cosmology, defense, general relativity, gravity, innovation, particle physics, philosophy, physics, policy, quantum physics, science, space travel

In 2014, I submitted my paper “A Universal Approach to Forces” to the journal Foundations of Physics. The 1999 Noble Laureate, Prof. Gerardus ‘t Hooft, editor of this journal, had suggested that I submit this paper to the journal Physics Essays.

My previous 2009 submission “Gravitational acceleration without mass and noninertia fields” to Physics Essays, had taken 1.5 years to review and be accepted. Therefore, I decided against Prof. Gerardus ‘t Hooft’s recommendation as I estimated that the entire 6 papers (now published as Super Physics for Super Technologies) would take up to 10 years and/or $20,000 to publish in peer reviewed journals.

Prof. Gerardus ‘t Hooft had brought up something interesting in his 2008 paper “A locally finite model for gravity” that “… absence of matter now no longer guarantees local flatness…” meaning that accelerations can be present in spacetime without the presence of mass. Wow! Isn’t this a precursor to propulsion physics, or the ability to modify spacetime without the use of mass?

As far as I could determine, he didn’t pursue this from the perspective of propulsion physics. A year earlier in 2007, I had just discovered the massless formula for gravitational acceleration g=τc^2, published in the Physics Essays paper referred above. In effect, g=τc^2 was the mathematical solution to Prof. Gerardus ‘t Hooft’s “… absence of matter now no longer guarantees local flatness…”

Is Photon Based Propulsion, the Future?

Posted by in categories: anti-gravity, defense, general relativity, gravity, innovation, particle physics, physics, quantum physics, science, space travel

I first met Dr. Young Bae, NIAC Fellow, at the Defense Advanced Research Projects Agency (DARPA) sponsored 2011, 100 Year Starship Study (100YSS) at Orlando, Fla. Many of us who were there had responded to the NASA/DARPA Tactical Technology Office’s RFP to set up an organization “… to develop a viable and sustainable non-governmental organization for persistent, long-term, private-sector investment into the myriad of disciplines needed to make long-distance space travel viable …”

Yes, both DARPA and NASA are at some level interested in interstellar propulsion. Mine was one of approximately 35 (rumored number) teams from around the world vying for this DARPA grant, and Dr. Bae was with a competing team. I presented the paper “Non-Gaussian Photon Probability Distributions”, and Dr. Bae presented “A Sustainable Developmental Pathway of Photon Propulsion towards Interstellar Flight”. These were early days, the ground zero of interstellar propulsion, if you would.

Dr. Bae has been researching Photon Laser Thrust (PLT) for many years. A video of his latest experiment is available at the NASA website or on YouTube. This PLT uses light photons to move an object by colliding with (i.e. transferring momentum to) the object. The expectation is that this technology will eventually be used to propel space crafts. His most recent experiments demonstrate the horizontal movement of a 1-pound weight. This is impressive. I expect to see much more progress in the coming years.

At one level, Dr. Bae’s experiments are confirmation that Bill Nye’s Light Sail (which very unfortunately lost communications with Earth) will work.

The Earth’s Evaporating Aquifers — By Robinson Meyer | The Atlantic

Posted by in category: water

“Many—if not most—of the Earth’s aquifers are in trouble. … That’s the finding of a group of NASA scientists, who published their study of global groundwater this week in the journal Water Resources Research. Water levels in 21 of the world’s 37 largest known aquifers, they report, are trending negative.”
