They found yet another reason to build nuclear interceptors to deflect asteroids and comet impact threats.

Sooner or later something is going to hit us. It could be like Tunguska in 1908 and destroy a city instead of a forest in Siberia- or it could be like what hit the Yucatan 65 million years ago.

Except just a little bigger and nothing larger than bacteria will survive. There is nothing written anywhere that says it will not happen tomorrow.

This essay was posted previously last year and removed and has appeared in abridged form in the European Space Safety online Magazine and can also be found on Yahoo voices.

Several dates are cited as marking the beginning of the space age. Sputnik, October 4th, 1957, Yuri’s day April 12th, 1961, and the first successful V-2 launch by the Nazis on October 3rd, 1942, to name a few. Some prefer December 21st, 1968, when human beings first escaped the Earth’s gravitational field on Apollo 8. When studying the events that allowed man to leave Earth, future historians may agree on a date not generally associated with space flight. July 16th, 1945 was Trinity, the first nuclear weapon test. Stanislaw Ulam, a 36-year-old Polish mathematician who helped build “the gadget”, visited ground zero after the test. Ulam later conceived the idea of propelling a spaceship with atomic bombs. Near the end of his life the eccentric genius stated the idea was his greatest work.

When considering nuclear propulsion, it must be understood that space is not an ocean, though often characterized as one. The distances and conditions are not comparable. While chemical energy has allowed humankind to travel across and above the surface of Earth, the energy required to travel in space is of a different order. Water, in the form of steam, was the agent of change that brought about the industrial revolution. Fossil fuel, burned and transformed by steam into mechanical work, would radically change the world in the span of a century. What is difficult for moderns to understand is not only how limited human capabilities were before steam, but how limited they are in the present in terms of space travel. The psychological limits of human beings limit space journeys to a few years. Chemical propulsion is not capable of taking human beings to the outer solar system and back within those crew limits. The solution is a reaction one million times more powerful. Nuclear energy is to the space age as steam was to the industrial age.

It’s the centennial year of the Titanic disaster, and that tragedy remains a touchstone.

The lifeboat angle is obvious. So is the ice hazard: then it was icebergs, now it’s comets.

But 100 years of expanding awareness has revealed the other threats we’re now aware of. We have to think about asteroids, nano- and genotech accidents, ill-considered high-energy experiments, economic and social collapse into oligarchy and debt peonage, and all the many others.

What a great subject for a Movie Night! Here are some great old movies about lifeboats and their discontents.

Here are links to NASA live broadcast of Curiosity’s landing on Mars. Curiosity is the one ton car-sized rover that NASA is landing on Mars today.

This is another step in Man’s great adventure into interstellar space. Well Done, NASA.

Tom Kerwick challenged my warnings by claiming that the observed longevity of white dwarfs, in spite of the constant bombardment by cosmic rays, provides a convincing safety argument regarding the currently running nuclear collisions experiment at CERN. This claim is important but, unfortunately, inconclusive as I shall try to demonstrate.

It is true that the collisions performed at CERN are relatively meager compared to cosmic-ray energies. The current, approximately 10 TeV collisions between equal-momentum particles at CERN correspond to 10.000 TeV cosmic ray protons hitting a stationary proton on earth or a white dwarf. The thousand-fold increase is a consequence of the relativistic energy-momentum law being applicable.

If 10.000 TeV (= 10 to the 16 electron volt) look like much, cosmic ray energies up to 10 to the 22 electron volt (a million times more) have been measured. However, if the latter are translated back into symmetric collisions of the CERN type, they are “only” a thousand times more energetic than CERN’s (owing to the square-root rule implicit in the mentioned law).

The fact that white dwarfs appear to be resilient to this bombardment is living proof that the cross section of CERN-generated miniature black holes (as well as their up to a thousand times more massive cosmic-ray generated analogs) must be minuscule. Specifically, their diameter must lie below that of a lepton (electron or quark). While an electron’s diameter is often supposed to be zero, neutrino absorption in solid matter yields a finite value (about ten to the negative 24 meter). In addition, the Telemach theorem guarantees a non-zero electron diameter.

While emailing back and forth with Ron Kita, I realized that it would be useful to compile a list of researchers who have published serious papers, past & present, in the new field of propulsion physics (gravity modification is an example) at least for the purpose of finding out how many countries are at some stage in this field.

This is important to do if we are to hasten the theoretical & technological development to leave Earth on a commercially feasible scale. I was surprised by what I found.

Below is the list. I’m sure it is not complete but it is a start. If you know of anyone who should be on this list, please let me know, and I will update this post.

Here are the ground rules for including a name.

- From Integrationalism

In April of 2010 the Library of Congress announced that it will acquire all of the public tweets for future generations to review. It’s quite the ambitious effort from a technological standpoint, considering all of the data migration and storage as the micro-blogging social network grows. The initiative also has some uncovered ethical and democratic potential that are currently being overlooked.

Twitter as a platform is empowering the creators of the world to understand how their co-conspirers and consumers are affecting the discovery, development, and delivery of new goods & services to be brought to market. For instance, Marketing and other R&D departments across the globe at the enterprise scale are using social networks like Twitter to monitor and improve their CRM (Customer Relationship Management) processes. These aren’t rigid customer service initiatives, but also customer discovery initiatives. Social networking is giving new meaning to the idea that supply & demand are never ending sphere of interaction; further, confusing the philosophical ideal of who might our creators and consumers be.

Recently Seth Shostak of the SETI Institute, wrote an article in the Huffington Post How to Find Extraterrestrial Life. He had proposed that the search for extraterrestrial life was a three-way horse race. According to Shostak:

(1) Discover Life Nearby: This is the search for life in our solar system.

(2) Sniff It Out: Do the sort of spectral analysis that might detect atmospheric gases caused by biology.

(3) Eavesdrop On ET: Otherwise known as SETI, is the effort to detect radio signals or laser flashes from technically savvy extraterrestrials.

In it he reports on a gorilla in a cage who could be brought to phrenetic laughter by his human friend’s pretending to bite him into his toe. Quote: “If you have never seen a gorilla in a fit of laughter, I recommend searching out such a sight before you pass from this world.”

This is absolutely human behavior. If you know about the cross-caring theory, which explains how a young child interacting with his bonding partner is getting “moved” into suspecting benevolence shown towards him, then you realize that the same thing can be accomplished with a caged or non-caged gorilla.

I recently mentioned Margaret Howe, a pupil of my late friend Gregory Bateson’s. There are important insights about the mission of humankind on our planet and beyond (“galactic export”) that would make it a great pity if this “second level of human social evolution on earth and in the solar system” was going to be clipped.

I know I am being impossible, but finding outrageous things that tickle everyone in her or his heart so as to be moved is the real mission of science. I fantasize talking with a gorilla – or orangutan – about the long-stretched “toe” of the visualized Schwarzschild metric of a black hole, both of us laughing.
