Lawrence Krauss Versus Freeman Dyson on Gravitons

Posted by in categories: alien life, engineering, genetics, particle physics, quantum physics, robotics/AI, space travel

Yesterday, in the New York Review of Books, Freeman Dyson analyzed a trio of recent books on humanity’s future in the larger cosmos. They were How to Make a Spaceship: A Band of Renegades, an Epic Space Race, and the Birth of Private Spaceflight; Beyond Earth: Our Path to a New Home in the Planets; and All These Worlds Are Yours: The Scientific Search for Alien Life.

Dyson is “a brilliant physicist and contrarian,” as the theoretical astrophysicist Lawrence Krauss recently told Nautilus. So I was waiting, as I read his review, to come across his profound and provocative pronouncement about these books, and it came soon enough: “None of them looks at space as a transforming force in the destiny of our species,” he writes. The books are limited in scope by looking at the future of space as a problem of engineering. Dyson has a grander vision. Future humans can seed remote environments with genetic instructions for countless new species. “The purpose is no longer to explore space with unmanned or manned missions, but to expand the domain of life from one small planet to the universe.”

Dyson can be just as final in his opinions on the destiny of scientific investigation. According to Krauss, Dyson once told him, “There’s no way we’re ever going to measure gravitons”—the supposed quantum particles underlying gravitational forces—“because there’s no terrestrial experiment that could ever measure a single graviton.” Dyson told Krauss that, in order to measure one, “you’d have to make the experiment so massive that it would actually collapse to form a black hole before you could make the measurement.” So, Dyson concluded, “There’s no way that we’ll know whether gravity is a quantum theory.”

Bioengineered bacteria could be used to 3D print food, medicine, and tools on Mars

Posted by in categories: 3D printing, bioengineering, biotech/medical, food, solar power, space travel, sustainability

Just like checking your bag on a commercial airline, space travel comes with some pretty big weight restrictions. How big? According to estimates, reaching space costs a whopping $10,000 per pound, which means that every ounce saved has a big impact on the bottom line.

That’s where a group of Danish researchers comes in. The team is working on a synthetic biology project called CosmoCrops, which hopes to use bacteria to make it possible to 3D print everything needed for a respectable space mission, using a cutting-edge co-culturing system. And it could even make life better for those of us back on Earth in the process.

“We are trying to make space exploration cheaper, because many inventions we use in our daily life were invented because of space exploration, like Velcro and solar energy,” Joachim Larsen, one of the students working on the project, told Digital Trends. “The way we want to achieve this is to [be] able to produce everything from food to medicine and bioplastic for 3D printers out in space — making the space rocket a lot lighter.”

It’s Official: We’re Going to Mars

Posted by in category: space travel

A bipartisan bill was passed by the U.S. Senate committee that oversees NASA space projects. The bill would allocate $19.5 billion in funds to NASA in 2017, but it has a critical mission for the space agency: send men to Mars.

The Science of Star Trek — Documentary 2016

Posted by in categories: education, physics, science, space travel

Is building our own starship Enterprise possible? Will we ever travel between the stars as easily as they do in Star Trek? JJ Abrams’ new feature, Star Trek Into Darkness, hits the screen in a golden age of scientific discoveries. HISTORY is there, giving viewers a deep look behind the scenes, on the set, and into the science–amazing new exoplanets, the physics of Warp drive, and the ideas behind how we might one day live in a Star Trek Universe.

Exotic Space Propulsion including Mach Propulsion and EMDrive will be discussed at Space Studies Institute conference

Posted by in categories: innovation, space travel

The Estes Park Advanced Propulsion Workshop, 20–22 September 2016, organized by the Space Studies Institute (SSI), will feature presentations by NASA Eagleworks scientist Paul March and Prof. Martin Tajmar, chair for Space Systems at the Dresden University of Technology, who last year presented an independent confirmation of the anomalous EmDrive thrust.

Other notable participants include Prof. James Woodward and Prof. Heidi Fearn, both from California State University, Fullerton, and Prof. David Hyland from Texas A and M University.

The 3-day conference will address at most 6 concepts for a breakthrough in propulsion. They are devoting a half-day per concept. The half-day is broken into theory and experiment sessions for the concept. The concept will be investigated on both grounds, with substantial give-and-take between the audience and the concept presenter, verbally and on the whiteboard.

Mach Effect Propulsion Theory Updates

Posted by in categories: information science, particle physics, space travel

Theory of a mach effect thruster I

The Mach Effect Thruster (MET) is a propellant—less space drive which uses Mach’s principle to produce thrust in an accelerating material which is undergoing mass—energy fluctuations. Mach’s principle is a statement that the inertia of a body is the result of the gravitational interaction of the body with the rest of the mass-energy in the universe. The MET device uses electric power of 100 — 200 Watts to operate. The thrust produced by these devices, at the present time, are small on the order of a few micro-Newtons. Researchers give a physical description of the MET device and apparatus for measuring thrusts. Next they explain the basic theory behind the device which involves gravitation and advanced waves to incorporate instantaneous action at a distance. The advanced wave concept is a means to conserve momentum of the system with the universe. There is no momentun violation in this theory. We briefly review absorber theory by summarizing Dirac, Wheeler-Feynman and Hoyle-Narlikar (HN). They show how Woodward’s mass fluctuation formula can be derived from first principles using the HN-theory which is a fully Machian version of Einstein’s relativity. HN-theory reduces to Einstein’s field equations in the limit of smooth fluid distribution of matter and a simple coordinate transformation.

It is shown that if Mach’s Principle is taken seriously, and the inertia of a body can be described as the interaction of the body with the rest of the universe, then the advanced and retarded fields transmitted between the particle and the universe can be used to explain the thrust observed in the Mach Effect drive experiments. This idea was originally put forward by one of the authors, James Woodward. The idea of inertia being a gravitational effect was first postulated by Einstein. In fact Mach’s principle was the foundation on which Einstein’s general relativity was based.

Russia Plans Lunar Settlement by 2045

Want to immigrate? Why not to Russian Space Settlement.


Roscosmos has revealed plans to send a manned mission to the moon between 2025 and 2045 – some 60 years after Neil Armstrong’s Apollo mission ended the space race between the US and Soviet Russia.

Russian Academy of Cosmonautics member Yury Karash previously said: “Back in the 1960s the Soviet Union was competing head-to-head with the United States.

Russia begins moon landing trials as Moscow ‘plans large lunar settlement’ by 2045

Posted by in category: space travel

RUSSIAN scientists have taken one small step back in time by using a communist-era gravity machine ahead of their planned mission to the moon.

Putin’s boffins are using the 1970s Selen technology to discover how easy it would be for their cosmonauts to walk on the lunar surface and get out of a rover vehicle.
