Eight of 347 scientists: Their achievement is above the fold in major newspapers

Yesterday (Sep 5, 2019), the Breakthrough Prize Foundation awarded $21.6 million US dollars to the scientists behind a stunning achievement. They imaged a black hole. Although the image was announced and released 5 months ago, the story is still unfolding.

Yesterday (Sep 5, 2019), the Breakthrough Prize Foundation awarded $21.6 million US dollars to the scientists behind a stunning achievement. They imaged a black hole. Although the image was announced and released 5 months ago, the story is still unfolding.

The Breakthrough Prize is funded by Russian-Israeli billionaire Yuri Milner. It is the highest-paying science prize for researchers in life science, math, and physics.

There are many black holes in our galaxy and some small ones in our own galactic “neighborhood” . Yet the EHT team* focused on M87, a black hole in the center of another Galaxy, 55 million light years from our solar system.

Why it is dangerous to build ever larger big bang machines

CERN has revealed plans for a gigantic successor of the giant atom smasher LHC, the biggest machine ever built. Particle physicists will never stop to ask for ever larger big bang machines. But where are the limits for the ordinary society concerning costs and existential risks?

CERN boffins are already conducting a mega experiment at the LHC, a 27km circular particle collider, at the cost of several billion Euros to study conditions of matter as it existed fractions of a second after the big bang and to find the smallest particle possible – but the question is how could they ever know? Now, they pretend to be a little bit upset because they could not find any particles beyond the standard model, which means something they would not expect. To achieve that, particle physicists would like to build an even larger “Future Circular Collider” (FCC) near Geneva, where CERN enjoys extraterritorial status, with a ring of 100km – for about 24 billion Euros.

Experts point out that this research could be as limitless as the universe itself. The UK’s former Chief Scientific Advisor, Prof Sir David King told BBC: “We have to draw a line somewhere otherwise we end up with a collider that is so large that it goes around the equator. And if it doesn’t end there perhaps there will be a request for one that goes to the Moon and back.”

“There is always going to be more deep physics to be conducted with larger and larger colliders. My question is to what extent will the knowledge that we already have be extended to benefit humanity?”

Solar System Map: Surprisingly deceptive

Posted by in categories: astronomy, cosmology, gravity, lifeboat, mapping, physics, space, space travel

What’s wrong with this illustration of the planets in our solar system? »

For one thing, it suggests that the planets line up for photos on the same solar ray, just like baby ducks in a row. That’s a pretty rare occurrence—perhaps once in several billion years. In fact, Pluto doesn’t even orbit on the same plane as the planets. Its orbit is tilted 17 degrees. So, forget it lining up with anything, except on rare occasions, when it crosses the equatorial plane. On that day, you might get it to line up with one or two planets.

But what about scale? Space is so vast. Perhaps our solar system looks like this ↓

No such luck! Stars and planets do not fill a significant volume of the void. They are lonely specs in the great enveloping cosmic dark.* Space is mostly filled with—well—space! Lots and lots of it. In fact, if Pluto and our own moon were represented by just a single pixel on your computer screen, you wouldn’t see anything around it. Even if you daisy chain a few hundred computer screens, you will not discern the outer planets. They are just too far away.

Stephen Hawking speaks with virtually no muscular movement

Posted by in categories: astronomy, biotech/medical, cosmology, gravity, physics, singularity, space, thought controlled

Next January Stephen Hawking will be 74 years old. He has lived much longer than most individuals with his debilitating condition. In addition to being an unquestionably gifted cosmologist, he has invited controversy by supporting the pro-Palestinian, Israel-BDS boycott and warning about the dangers of alien invaders who tap into our interstellar greetings

Antisemitism, notwithstanding, this man is a mental giant. He is Leonardo. He is Einstein. Like them, his discoveries and theories will echo for generations beyond his life on earth. He is that genius.


Forty years ago, when Stephen Hawking still had mobility, he delivered a paper on a mystery regarding information-loss for entities that cross the event boundary of a black hole.

In the mid 1970s, Astronomers were just discovering black holes and tossing about various theories about the event horizon and its effect on the surrounding space-time. Many individuals still considered black holes to be theoretical. Hawking’s analysis of the information paradox seemed extremely esoteric. Yet, last month (Aug 2015) , at Sweeden’s KTH Royal Institute of Technology, Hawking presented a possible solution to the paradox that he sparked.

Slow death of Universe confirmed with precision

Posted by in categories: astronomy, cosmology, gravity, physics, space
  • The universe radiates only half as much energy as 2 billion years ago
  • New findings establish cosmos’ decline with unprecedented precision


From CNN
—The universe came in with the biggest bang ever. But now, with a drooping fizzle, it is in its swan song. The conclusion of a new astronomical study pulls no punches on this: “The Universe is slowly dying,” it reads.

Astronomers have believed as much for years, but the new findings establish the cosmos’ decline with unprecedented precision. An international team of 100 scientists used data from the world’s most powerful telescopes — based on land and in space — to study energy coming from more than 200,000 galaxies in a large sliver of the observable universe. [Full story below or at CNN.com]…

Based on those observations, they have confirmed the cosmos is radiating only half as much energy as it was 2 billion years ago. The astronomers published their study on Monday on the website of the European Southern Observatory.

Analysis across many wavelengths shows the universe's electromagnetic energy output is dropping.The team checked the energy across a broad spectrum of lightwaves and other electromagnetic radiation and says it is fading through all wavelengths, from ultraviolet to far infrared.

Universe might contain millions of black holes

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

[from Engadget]

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…”

Honda’s Gravity Modification Research

Posted by in categories: anti-gravity, business, cosmology, defense, disruptive technology, engineering, general relativity, gravity, innovation, particle physics, physics, quantum physics, science, space travel

Gravity modification, the scientific term for antigravity, is the ability to modify the gravitational field without the use of mass. Thus legacy physics, the RSQ (Relativity, String & Quantum) theories, cannot deliver either the physics or technology as these require mass as their field origin.

Ron Kita who recently received the first US patent (8901943) related to gravity modification, in recent history, introduced me to Dr. Takaaki Musha some years ago. Dr. Musha has a distinguished history researching Biefeld-Brown in Japan, going back to the late 1980s, and worked for the Ministry of Defense and Honda R&D.

Dr. Musha is currently editing New Frontiers in Space Propulsion (Nova Publishers) expected later this year. He is one of the founders of the International Society for Space Science whose aim is to develop new propulsion systems for interstellar travel.

Wait. What? Honda? Yes. For us Americans, it is unthinkable for General Motors to investigate gravity modification, and here was Honda in the 1990s, at that, researching this topic.

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.
