Debunked: Questions No Atheist Can Answer

The Law of Attraction – Debunked (The Secret – Refuted)

1. Pseudoscience:

So the first thing to be said, in my opinion, is that the Law of Attraction, and, to be blunt, New Age Thought altogether, is entirely predicated on dispensing meaningless drivel masqueraded as profound truth and wisdom… it is, to paraphrase Michael Shermer, the combination of scientific sounding words with New Age words to create the illusion that they’re somehow related…

For example, the term ‘Law of Attraction’ deliberately implies that it is a scientific law, just like the ‘Law of Conservation of Energy’ etc., and yet, science regards the Law of Attraction as pure nonsense and pseudoscience, and puts it in the same bin as creationism, homeopathy, climate change denial and tin foil hats!

2. Argument from Ignorance:

Anyhow, with that said, the first question to be asked is if the first premise is true – is everything really comprised of energy vibrating at different frequencies? Is the Law of Vibration true? Well, while it is true that everything so far appears to be an expression of matter and energy, and while matter and energy are indeed different states of the same thing (energy)… the only way someone can say that everything “vibrates” is by defining ‘vibration’ to be “energy in motion” – which only serves to confuse people.

What’s more is that if the proponents of this argument go a step further and assert that we know for sure that everything is vibrating energy, they’re actually committing an Argument from Ignorance, because absence of evidence is not evidence of absence.

Proposed Time Machine Could Also Clone Objects

Access to the past would open all sorts of new possibilities of more than travel.

By Charles Q. Choi, ISNS Contributor via Inside Science

time_250px(ISNS) — Time travel is often a way to change history in science fiction such as “Back to the Future” and “Looper.” Now researchers suggest a certain kind of time machine could also possess another powerful capability — cloning perfect copies of anything.

However, scientists noted the way these findings violate what is currently known about quantum physics might instead mean such time machines are not possible.

We are all time travelers in that we all move forward in time. However, scientists have suggested it might be possible to move back in time by manipulating the fabric of space and time in our cosmos. All mass distorts space-time, causing the experience of gravity, a bit like how a ball sitting on a rubber sheet would make nearby balls on the sheet roll toward it. Physicists have proposed time machines that could bend the fabric of space and time so much that timelines actually turn back on themselves,  forming loops technically known as “closed timelike curves.”

These space-time warps can develop because of wormholes — tunnels that can in theory allow travel anywhere in space and time, or even into another universe. Wormholes are allowed by Einstein’s general theory of relativity, although whether they are practically possible is another matter.

A key limitation of this kind of time machine would be that any traveler using it cannot go back to a time before the device was built. It only permits travel from the future back to any point in time after the machine was constructed.

Scientists have for decades explored what closed timelike curves are capable of if they are possible.

One complication they would encounter is the no-cloning theorem in quantum physics, which basically forbids the creation of identical copies of any particle one does not know everything about to begin with.

wormhole_by_stefitms_250pxIn classical physics, one can generate a perfect copy of anything by finding out every detail about it and arranging the same components in the same order. However, in the bizarre world of quantum physics — the best description so far of how reality behaves on its most fundamental levels — one cannot perfectly measure every detail of an object at once. This is related to Heisenberg’s uncertainty principle, which notes that one can perfectly measure either the position or the momentum of a particle, but not both with unlimited accuracy.

Nearly 25 years ago, theoretical physicist David Deutsch at the University of Oxford in England suggested closed timelike curves might actually violate the no-cloning theorem, allowing perfect copies to be constructed of anything. Now scientists reveal this might be true in findings detailed in the Nov. 8 issue of the journal Physical Review Letters.

To understand this research, imagine one builds a time machine in the year 2000. One could place a letter into the device in the year 3000 and pick it up within this box in 2000 or any year between then and 3000. From the perspective of the letter, it goes inside this time machine into one mouth of a wormhole in the future and comes out the other mouth of the wormhole in the past.

However, theoretical physicist Mark Wilde at Louisiana State University, in Baton Rouge, and his colleagues found this scenario may be more complex than previously thought. Instead of the time machine containing just one wormhole, it could possess many wormholes, each at some point in time between the future and the moment of its creation. A letter entering the box in 3000 might exit from a wormhole in 2999, instantaneously go back into that wormhole and emerge in 2998, and so on.

“It’s like there are 1,000 different particles emerging from all the wormholes, but in fact they’re all the same particle you sent in the beginning,” Wilde said. “You just have all these temporary copies emerging from and going back into these wormholes.”

Inertial Propulsion and Other Delusions

steven_novellaby via NeuroLogica Blog

Some ideas are so compelling and seductive it seems there will always be those who succumb to their siren song. We easily understand how transformative these technologies will be and can’t help feeling that if we work hard enough, we can achieve them – the panacea, free energy, anti-gravity, and regeneration to name a few.

perpetual motion 7043BFree energy and anti-gravity machines attract engineers and tinkerers who cannot help but think that if they can figure out the proper arrangement of moving parts, they can bypass the laws of physics. Over the decades they have produced often complex and sometimes elegant machines that seem like they might work, but always always they miss something subtle.

The pattern by now is very clear, and depressingly repetitive. The inventor spends years developing a machine to exploit some physical property, such as the interaction of magnets, or the seemingly funny physics of rapidly rotating systems. Their scale models seem to do what they are supposed to – usually they spin. At some point the inventor believes they are ready to show their incipient invention to the world, perhaps now they are ready to attract major investors to help build the full scale operating versions of their technology.

What they present to the world are complex diagrams, and scale models that do something, but never what they are claimed to do. We never see a free energy device actually producing energy and running electrical devices without any outside input or burning of fuel. We never see anti-gravity devices levitating.

Of course, if the inventors could actually produce what they claim, they would garner serious attention. Instead they are largely ignored and criticized – their years, even decades, of loving labor dismissed. How can this be? They must simply be too far ahead of their time for the rubes to understand their genius. Plus, there must be some sinister conspiracy working against them – Big Oil or whatever.

It’s sad – another mind, perhaps even brilliant in their way, lost to the allure of the impossible.

Inertial Propulsion

perpetual motion 702BThere are many phrases that are used to refer to impossible technologies. What seems to happen is that proponents come up with a term for their invention. Their invention is found to be nothing but a fantasy, and the term becomes associated with negative connotations. The next generation of proponents then come up with a new technical term, and the cycle continues.

So perpetual motion machines become free energy machines, then zero-point energy, then over-unity machines, etc.

Last year, January of 2013, an inventor by the name of Rick R. Dobson revealed his “closed loop propulsion” technology – the product of 27 years of development. Closed-loop propulsion is a synonym for inertial propulsion, or massless propulsion. He also calls his technology centrifugal propulsion.

The idea behind such technologies is to produce propulsion without any propellant. Propellant is one of those annoying necessities of physics.

Do We Live in the Matrix?


Tests could reveal whether we are part of a giant computer simulation — but the real question is if we want to know…

By Zeeya Merali via DiscoverMagazine.com

In the 1999 sci-fi film classic The Matrix, the protagonist, Neo, is stunned to see people defying the laws of physics, running up walls and vanishing suddenly. These superhuman violations of the rules of the universe are possible because, unbeknownst to him, Neo’s consciousness is embedded in the Matrix, a virtual-reality simulation created by sentient machines.

matrix-red_02_250pxThe action really begins when Neo is given a fateful choice: Take the blue pill and return to his oblivious, virtual existence, or take the red pill to learn the truth about the Matrix and find out “how deep the rabbit hole goes.”

Physicists can now offer us the same choice, the ability to test whether we live in our own virtual Matrix, by studying radiation from space. As fanciful as it sounds, some philosophers have long argued that we’re actually more likely to be artificial intelligences trapped in a fake universe than we are organic minds in the “real” one.

But if that were true, the very laws of physics that allow us to devise such reality-checking technology may have little to do with the fundamental rules that govern the meta-universe inhabited by our simulators. To us, these programmers would be gods, able to twist reality on a whim.

So should we say yes to the offer to take the red pill and learn the truth — or are the implications too disturbing?

Worlds in Our Grasp

The first serious attempt to find the truth about our universe came in 2001, when an effort to calculate the resources needed for a universe-size simulation made the prospect seem impossible.

matrix alternate reality_250pxSeth Lloyd, a quantum-mechanical engineer at MIT, estimated the number of “computer operations” our universe has performed since the Big Bang — basically, every event that has ever happened. To repeat them, and generate a perfect facsimile of reality down to the last atom, would take more energy than the universe has.

“The computer would have to be bigger than the universe, and time would tick more slowly in the program than in reality,” says Lloyd. “So why even bother building it?”

But others soon realized that making an imperfect copy of the universe that’s just good enough to fool its inhabitants would take far less computational power. In such a makeshift cosmos, the fine details of the microscopic world and the farthest stars might only be filled in by the programmers on the rare occasions that people study them with scientific equipment. As soon as no one was looking, they’d simply vanish.

In theory, we’d never detect these disappearing features, however, because each time the simulators noticed we were observing them again, they’d sketch them back in.

That realization makes creating virtual universes eerily possible, even for us.
