Our Universe is Fine Tuned for Life—Why?
Posted by Philip Raymond in categories: astronomy, chemistry, cosmology, gravity, physics, space
Consider how many natural laws and constants—both physical and chemical—have been discovered since the time of the early Greeks. Hundreds of thousands of natural laws have been unveiled in man’s never ending quest to understand Earth and the universe.
I couldn’t name 1% of the laws of nature and physics. Here are just a few that come to mind from my high school science classes. I shall not offer a bulleted list, because that would suggest that these random references to laws and constants are organized or complete. It doesn’t even scratch the surface…
Newton’s Law of force (F=MA), Newton’s law of gravity, The electromagnetic force, strong force, weak force, Avogadro’s Constant, Boyle’s Law, the Lorentz Transformation, Maxwell’s equations, laws of thermodynamics, E=MC2, particles behave as waves, superpositioning of waves, universe inflation rate, for every action… etc, etc.
For some time, physicists, astronomers, chemists, and even theologians have pondered an interesting puzzle: Why is our universe so carefully tuned for our existence? And not just our existence—After all, it makes sense that our stature, our senses and things like muscle mass and speed have evolved to match our environment. But here’s the odd thing—If even one of a great many laws, properties or constants were off by even a smidgen, the whole universe could not exist—at least not in a form that could support life as we imagine it! Even the laws and numbers listed above. All of creation would not be here, if any of these were just a bit off…

To be a Space Faring Civilization
Posted by Benjamin T. Solomon in categories: astronomy, cosmology, human trajectories, innovation, science, space, space travel, transportation
Until 2006 our Solar System consisted essentially of a star, planets, moons, and very much smaller bodies known as asteroids and comets. In 2006 the International Astronomical Union’s (IAU) Division III Working Committee addressed scientific issues and the Planet Definition Committee address cultural and social issues with regard to planet classifications. They introduced the “pluton” for bodies similar to planets but much smaller.
The IAU set down three rules to differentiate between planets and dwarf planets. First, the object must be in orbit around a star, while not being itself a star. Second, the object must be large enough (or more technically correct, massive enough) for its own gravity to pull it into a nearly spherical shape. The shape of objects with mass above 5×1020 kg and diameter greater than 800 km would normally be determined by self-gravity, but all borderline cases would have to be established by observation.
Third, plutons or dwarf planets, are distinguished from classical planets in that they reside in orbits around the Sun that take longer than 200 years to complete (i.e. they orbit beyond Neptune). Plutons typically have orbits with a large orbital inclination and a large eccentricity (noncircular orbits). A planet should dominate its zone, either gravitationally, or in its size distribution. That is, the definition of “planet” should also include the requirement that it has cleared its orbital zone. Of course this third requirement automatically implies the second. Thus, one notes that planets and plutons are differentiated by the third requirement.
As we are soon to become a space faring civilization, we should rethink these cultural and social issues, differently, by subtraction or addition. By subtraction, if one breaks the other requirements? Comets and asteroids break the second requirement that the object must be large enough. Breaking the first requirement, which the IAU chose not address at the time, would have planet sized bodies not orbiting a star. From a socio-cultural perspective, one could suggest that these be named “darktons” (from dark + plutons). “Dark” because without orbiting a star, these objects would not be easily visible; “tons” because in deep space, without much matter, these bodies could not meet the third requirement of being able to dominate its zone.

Reviewer’s comments: “Benjamin is the second researcher I have met who has tried to consider a nonsingular cosmology. The first was Christi Stoica, which I met in 2010″.
Andrew Beckwith PhD
The Objective: This book, Super Physics for Super Technologies, proposes that a new physics exists. The findings are based on 16 years of extensive numerical modeling with empirical data, and therefore, both testable and irrefutable.

New Book: An Irreverent Singularity Funcyclopedia, by Mondo 2000’s R.U. Sirius.

Quoted: “Legendary cyberculture icon (and iconoclast) R.U. Sirius and Jay Cornell have written a delicious funcyclopedia of the Singularity, transhumanism, and radical futurism, just published on January 1.” And: “The book, “Transcendence – The Disinformation Encyclopedia of Transhumanism and the Singularity,” is a collection of alphabetically-ordered short chapters about artificial intelligence, cognitive science, genomics, information technology, nanotechnology, neuroscience, space exploration, synthetic biology, robotics, and virtual worlds. Entries range from Cloning and Cyborg Feminism to Designer Babies and Memory-Editing Drugs.” And: “If you are young and don’t remember the 1980s you should know that, before Wired magazine, the cyberculture magazine Mondo 2000 edited by R.U. Sirius covered dangerous hacking, new media and cyberpunk topics such as virtual reality and smart drugs, with an anarchic and subversive slant. As it often happens the more sedate Wired, a watered-down later version of Mondo 2000, was much more successful and went mainstream.”

INTERSTELLAR – Blockbuster Movie features Decisive Black-Hole Effect
Posted by Otto E. Rössler in category: cosmology
The movie is grandiose and beautifully done. Especially the young girl at the outset is an incredibly strong real-life personality. The movie brings together the issue of planetary survival – under the onslaught of a never explained progressive lethal scourge – with the redeeming power of black holes used as a vehicle to reach a distant twin earth to be colonized by a select few.
The scenario is ingenious because the two topics – planetary survival and black holes – are intertwined on our own planet as well. The movie therefore functions much like a nightly dream which reshuffles some elements of the daylight reality to enable the sleep to go on while still remaining decipherable after waking up. The current terrestrial situation is not at all unrelated – with black holes figuring decisively in it as well.
In this optically and acoustically overwhelming immersion, for the first time in history the basic effect which a black hole exerts on its vicinity is made palpable. The viewer becomes an eyewitness to the emotional ordeal gone through by the protagonist (a trained jet pilot originally) when he suddenly realizes what it means that he and his buddy are by a technical problem forced to stay for a few more minutes fairly deep down in the gravitational funnel of a giant black hole: That this means that decades will pass by on the outside during those very minutes – so his young daughter whom he so much longs to see again will afterwards be older than he is now. And indeed, when he returns at the end of the movie, she is lying on her death bed in old age, with all her descendants assembled around her.
The movie thereby makes “gravitational time dilation” a palpable experience on the viewer’s own body and mind. And it does the same thing to the specialists’ minds, so I am sure. Textbook knowledge can never replace being made an eyewitness in person. You are now able to realize yourself what happens if you get even closer to the surface (or “horizon” as my friend Wolfgang Rindler named it) of a black hole. The answer is that you will in the limit of going down to the horizon itself be faced with an infinitely old universe on your return.
