james-randi-69Can psychics predict the future? Many people seem to think so. Others argue that, in most cases, so-called psychic experiences are really misinterpretations of events. In this episode of NOVA, magician and confirmed skeptic James Randi challenges viewers to weigh the evidence for and against the existence of psychic phenomena.

Randi argues that successful psychics depend on the willingness of their audiences to believe that what they see is the result of psychic powers. The program highlights some of the methods and processes he uses to examine psychics’ claims. Using his own expertise in creating deception and illusion, Randi challenges specific psychics’ claims by duplicating their performances and “feats,” or by applying scientific methods. His goal is to eliminate all possible alternative explanations for the psychic phenomena. He also looks for evidence that they are not merely coincidental. His arguments can motivate your class to discuss the differences between psychic performances and legitimate cases of unexplained phenomena.

The Case of the Ancient Astronauts – Erich von Däniken

This Nova documentary The Case of the Ancient Astronauts destroys the claims made by Erich von Däniken and his looney ancient astronauts (alien) theory. Read more about von Däniken below the video.

Enjoy 🙂

From Wikipedia:

Erich Anton Paul von Däniken (/ˈɛrk fɒn ˈdɛnkn/; German: [ˈeːrɪç fɔn ˈdɛːnɪkən]; born 14 April 1935) is a Swiss author of several books which make claims about extraterrestrial influences on early human culture, including the best-selling Chariots of the Gods?, published in 1968. Däniken is one of the main figures responsible for popularizing the “paleo-contact” and ancient astronauts hypotheses. The ideas put forth in his books are rejected by a majority of scientists and academics, who categorize his work as pseudohistory, pseudoarchaeology and pseudoscience.[1][2][3]

The Nova documentary The Case of the Ancient Astronauts shows that all the claims made by von Däniken about the Pyramid of Cheops were wrong in all accounts. The technique of construction is well understood, scholars know perfectly what tools were used, the marks of those tools in the quarries are still visible, and there are many tools preserved in museums. Däniken claims that it would have taken them too long to cut all the blocks necessary and drag them to the construction site in time to build the Great Pyramid in only 20 years, but Nova shows how easy and fast it is to cut a block of stone, and shows the rollers used in transportation. He also claims that Egyptians suddenly started making pyramids out of nowhere, but there are several pyramids that show the progress made by Egyptian architects while they were perfecting the technique from simple mastabas to later pyramids. Däniken claims that the height of the pyramid multiplied by one million was the distance to the Sun, but the number falls too short. If it were true, it would make the pyramid 93 miles high… He also claims that Egyptians could not align the edges so perfectly to true North without advanced technology that only aliens could give them, but Egyptians knew of very simple methods to find North via star observation, and it is trivial to make straight edges.[36]

Ancient Astronauts – Erich Anton Paul von Däniken

From The Skeptic’s Dictionary

Chariots of the GodsThe term ‘ancient astronauts’ designates the speculative notion that aliens are responsible for the most ancient civilizations on earth. The most notorious proponent of this idea is Erich von Däniken, author of several popular books on the subject. His Chariots of the Gods? Unsolved Mysteries of the Past, for example, is a sweeping attack on the memories and abilities of ancient peoples. Von Däniken claims that the myths, arts, social organizations, etc., of ancient cultures were introduced by astronauts from another world. He questions not just the capacity for memory, but the capacity for culture and civilization itself, in ancient peoples. Prehistoric humans did not develop their own arts and technologies, but rather were taught art and science by visitors from outer space.

Where is the proof for von Däniken’s claims? Some of it was fraudulent. For example, he produced photographs of pottery that  he claimed had been found in an archaeological dig. The pottery depicts flying saucers and was said to have been dated from Biblical times. However, investigators from Nova (the fine public-television science program) found the potter who had made the allegedly ancient pots. They confronted von Däniken with evidence of his fraud. His reply was that his deception was justified because some people would only believe if they saw proof (“The Case of the Ancient Astronauts,” first aired 3/8/78, done in conjunction with BBC’s Horizon and Peter Spry-Leverton)!

Most of von Däniken’s evidence is in the form of specious and fallacious arguments . . .

11 Ways to REALLY destroy the Earth

End times
By via The Soap Box

For years and years everyone from science fiction writers to scientists have been talking about all of these scenarios and what not about how the world will end (be it by our own hands, or a random act of nature).

While I find many of these scenarios interesting, many of them have a common flaw: they don’t actually end the Earth, just human civilization, and perhaps the human species.

So, how exactly could the Earth REALLY be destroyed (as in cease to exist)?

Well I’ve thought about it, and I’ve come up with about 11 different ways of how it could happen.

So if you don’t mind possibly being scared to death, below are those 11 possible scenarios:

• Planetary impact

planet-impact_250pxWe all know the dangers that a direct impact from either a comet or meteor poses to the Earth as it has been the subject of several movies and books, and is a legitimate threat because it has happened before, and it has wiped out entire species and caused major damage to the Earth throughout our planet’s history.

While some people might believe that it would be the end of the world if a large meteor or comet was to hit us today, it wouldn’t be. It might be the end of human civilization, maybe even our species, but the world will still exist… unless something really big, or really heavy was to hit us…

Lets say something nearly the size of the Earth, or bigger, was to hit us, or something very heavy like a neutron star. The fact is that there would be no way for the Earth to survive an impact by something close to, or larger, or heavier than the Earth. Our world would be broken apart and probably turned into an asteroid field by such an impact.

• High speed impact

The amount of damage a object can do not only depends on how large an object is, but also by how fast said object is going.

A one mile wide meteor hitting the Earth would be devastating. If that one mile wide meteor was to hit the Earth while traveling nearly the speed of light, the amount of kinetic energy released from such an impact would rip the Earth apart, and we wouldn’t even know it until it actually happened (assuming we survived long enough) because such an object would most likely be impossible to find, let alone track.

von Neumann machine

terminator_250pxA von Neumann machine is a type of robot first conceived of by John von Neumann (hence the name) that can basically self replicate, and could even manufacture materials on it’s own in order to do so. It would even be possible for it to seek out the resources it needs to manufacture those materials.

While such a machine would be an extraordinary leap forward in terms of robotics and manufacturing, some people fear that one day one of those robots could go haywire (or someone could build one for the purpose of unregulated self replicating) and continue to self replicate without knowing when to shut off, and ultimately end up destroying the Earth a small part at a time until there is nothing left.

While a larger machine might not actually be able to do this before we stopped it, a small machine like a nano-probe might just be able to do this.

• Knocked into the sun

Lets say a very large object (like a star) was to pass through our solar system, what do you think would happen?

The answer is that the Earth would be knocked out of orbit.

After that one of two things would then happen: The Earth would be knocked away from the sun and become a rogue planet (as well as a giant ball of ice), or we would get knocked into the sun and be burnt into nothing.

Super Laser

DeathStarLaser_300pxIf you’ve ever seen Star Wars then you probably know what I’m talking about, if you don’t then I’ll explain (although I do still recommend seeing Star Wars).

laser is a device that creates a focused beam of light that can actually be quiet destructive, and depending on how much energy you put into the laser, it’s destructive power can range from being harmless (unless you look directly into the beam) to being used to take out a vehicle. Taking this in mind it is theoretically possible to build a laser powerful to destroy the Earth.

Fortunately we don’t have to worry about this one right now due to the fact that the total amount of energy produced world wide is no where near enough to power a laser that would be capable of doing so.
