Dark Visitor

The Future of Western World

The western world has lost jobs and technological leadership to Asian nations. (We can’t make a flat-screen display, most consumer electronics, digital cameras, etc.) If current trends of "hip" students to avoid the harder sciences continues, leadership in scientific research will also be exported, along with most good jobs. Dark Visitor was written by a concerned retired physics professor, (36 years at Johns Hopkins University & their Applied Physic Lab.) to try to interest more students in scientific careers. Dark Visitor is based on the following real threat to earth (Only the "when" is speculative. The physics is valid.):


When the universe was young...

When the universe was young, it was smaller, denser, and had more hydrogen.(Stars consume hydrogen.) Large stars, that form black holes when they die, were the rule. They aged rapidly and left many generations of stellar-core black holes behind long before our sun was born. Consequently, there are now more of these small black holes than all of the current stars, but they can not be seen. (Black holes do not reflect light.) Most stars usually form in pairs (to conserve angular momentum of their original hydrogen gas cloud). The larger of two black holes formed by "sister stars" may have passed far from the sun in the late 1920s. It perturbed Neptune’s orbit and tilted Pluto's orbit plane. Pluto did not perturb Neptune, as is widely believed. (Pluto is smaller than the moon; Neptune is 17.2 times larger than the earth, and they are never closer than 17 astronomical units (the sun/ earth distance).

Current perturbations of Pluto’s orbit seem to indicate that the second of these sister black holes will pass by the sun in late 2007, more distant that Saturn’s orbit. It has 2.2 solar masses. Its gravity will slightly modify earth’s orbit, producing a 378-day year and eccentricity of 0.0836. A rapid-onset ice age will begin in 2008 and accelerate as earth’s albedo increases. By 2025, Washington DC will be buried under 100 feet of ice. Before that, all of the world’s ports will be useless. (Ocean levels drop, as ice is stored on land.) --- All this and more in Dark Visitor.

Dark Visitor is a physics book disguised as a scary novel. Read it if you dare and want to learn some physics without being "taught" textbook style.

A Dark Visitor from space is bringing Mankind’s Worst Catastrophe !

The following article appeared on page 18 of The Triangle, Drexel University’s Newspaper 27 February 2004. (It also is an effort to interest students in physics and astronomy.) If you have access to bulletin boards that high school students view, please print and post it. Thanks.

No escape: a black hole is coming for you


You are doomed by the laws of physics and ancient history.

Your fate was sealed when the universe was young – back when stars first began to form, long before our sun was born. The universe was much smaller and denser then. For many stellar generations, the typical star was much bigger than the sun. These large stars run through their life cycles much more rapidly than the sun. They first convert hydrogen to helium, then helium to carbon using unstable beryllium as an intermediary. Finally, at the end of their exothermic nuclear fusion cycles, they produce iron cores that implode. - The outer layers of a massive star’s iron core weigh so much that the iron below them can not support their weight. The core begins to collapse. When it is half its initial size, these outer layers weigh four times more. Thus the collapse accelerates as it progress. In the final stages of the collapse, the outer layers are falling inward to a single point at essentially the speed of light. In less than a minute, a mass greater than the sun collapses into a space much smaller than the period that ends this sentence. That is, a "black hole" is formed.

All of the mass in a black hole is concentrated in zero volume, but a roughly spherical space around this mass is so distorted that nothing, not even light, can escape. Because of this fact, an approaching black hole would not reflect sunlight nor be visible in telescopes. The first indication that a black hole was approaching our solar system would be slight perturbation in the orbits of Oort Cloud objects (small "planetesimals" more distant than Pluto) These objects and Pluto are frequently perturbed because they are small and weakly bound to the sun. Recent perturbations of Pluto can be interpreted as the approach of a still very distant black hole. Read Dark Visitor, for one such interpretation. It predicts that the second member of a pair of black holes will pass through the solar system in late 2007 and tip the earth back into an ice age, even though the approaching black hole is small (2.2 solar masses) and passes by the sun more distant than Saturn’s orbit. Is there any reason to think that this could be true? Unfortunately there is, as the next paragraph demonstrates.

First note that in the early universe many generations of typical stars formed black holes and that stars usually form in pairs. Thus there are currently more pairs of small stellar-core black holes than all the current stars. One probably passed by our solar system in the late 1920s. Neptune’s orbit was disturbed then. Pluto was discovered in 1930 after a yearlong search for the origin of this perturbation, but it is now known that Pluto was not the cause. (Pluto is smaller than the moon and Neptune is 17.2 times greater than the earth.) Any knowledgeable astronomer will confirm this fact. Although other explanations are possible, it seems probable that: (1) a stellar-core black hole was the cause and if this is true, then (2) the authors of Dark Visitor may be correct and we are doomed.
