FTL – Finally a possibility in mainstream science

Every now and then, a piece of news begs you to stop, rise above the mundane world of everyday life and reach for the stars and this month… it literally made it possible to reach for the stars – well almost, at least in theory!

Finally two physicists at Baylor University, US, have stumbled upon an idea that may turn traveling at the speed of light from science fiction to real science, just like the warp speed at which spacecraft travel in the fictional TV and film series ‘Star Trek’

Dr. Gerald Cleaver, associate professor of physics at Baylor, and Dr. Richard Obousy, a Baylor post-doctoral student, theorize that by manipulating the space-time dimensions around the spaceship with a massive amount of energy, it would create a “bubble” that could push the ship faster than the speed of light.

To create this bubble, the Baylor physicists believe manipulating the 11-dimension would create dark energy. Cleaver said that positive dark energy is responsible for speeding up the universe as time moves on, just like it did after the Big Bang, when the universe expanded faster than the speed of light.

“Think of it like a surfer riding a wave,” said Cleaver, who co-authored a research paper with Obousy about the new method. “The ship would be pushed by the bubble and the bubble would be traveling faster than the speed of light,” he added.

The method is based on the Alcubierre drive, which proposes expanding the fabric of space behind a ship into a bubble and shrinking space-time in front of the ship.

According to Wikipedia - Alcubierre drive - also known as the Alcubierre drive or Warp Drive, is a speculative mathematical model of a space-time exhibiting features reminiscent of the fictional "warp drive" from Star Trek, which can travel "Faster-than-light".

In 1994, the Mexican physicist Miguel Alcubierre proposed a method of stretching space in a wave which would in theory cause the fabric of space ahead of a spacecraft to contract and the space behind it to expand. The ship would ride this wave inside a region known as a warp bubble of flat space. Since the ship is not moving within this bubble, but carried along as the region itself moves, conventional relativistic effects such as time dilation do not apply in the way they would in the case of a ship moving at high velocity through flat space-time. Also, this method of travel does not actually involve moving faster than light in a local sense, since a light beam within the bubble would still always move faster than the ship; it is only "faster than light" in the sense that, thanks to the contraction of the space in front of it, the ship could reach its destination faster than a light beam restricted to travelling outside the warp bubble. Thus, the Alcubierre drive does not contradict the conventional claim that relativity forbids a slower-than-light object to accelerate to faster-than-light speeds. However, there are no known methods to create such a warp bubble in a region that does not already contain one, or to leave the bubble once inside it, so the Alcubierre drive remains a theoretical concept at this time.

The ship would not actually move, rather the ship would sit in between the expanding and shrinking space-time dimensions. Since space would move around the ship, the theory does not violate Einstein’s Theory of Relativity, which states that it would take an infinite amount of energy to accelerate an object faster than the speed of light.

String theory suggests the universe is made up of multiple dimensions. Height, width and length are three dimensions, and time is the fourth dimension. Scientists believe that there are a total of 10 dimensions, with six other dimensions that we cannot yet identify. A new theory, called M-theory, takes string theory one step farther and states that the “strings” actually vibrate in an 11-dimensional space. It is this 11th dimension that the Baylor researchers believe could help propel a ship faster than the speed of light.

Gee – the only thing left to invent now is “inertial dampening” and “shields” J I wonder what Zefram Cochrane would have thought of this…

So…the theory is there. Implementation waits the perception of our current technologies in higher dimension. Accelerating masses generate gravitational radiation in higher dimension. That side of the universe in completely dark for us as we cannot perceive anything beyond the three spatial dimensions and one forward moving time dimension.

The theory of relativity predicts that masses being accelerated should emit ``gravitational radiation’’ in the same way that charged particles (like electrons) emit electromagnetic radiation when they are accelerated.

Simply put use of gravitational wave in higher dimensions easily produce thousand time faster speed than light. The waves and radiations that we can perceive are designed to explicitly manifest themselves in 3-d spatial environments. Gravity radiation is what runs the chilled universe, the Hyperspaces and zillion universes held by the chilled platform universe.

I think this piece of theoretical work has important connotations for humanity and its future and I for one would closely follow any developments – theoretical or experimental in this field…

Quantum physics and consciousness

Today was the day of connecting with inner self. So I spent the afternoon going through some books on consciousness and its connection with quantum physics.

For more than two hundred years Newton’s ideas dictated our world view. Newton declared that everything operates mechanically and can be predicted like clockwork. Science in Newton’s view, being nothing more than the act of observing, meant that this world view was easily perpetuated by independent observers all over the world.

In the late 19th century, science entered into the era of subatomic physics, which changed everything. Scientists discovered that the so-called ‘subatomic particles’ were not particles at all. They behaved like particles when they were measured but they traveled like waves. Quantum theory has changed everything, because what was once a mechanical, external universe has now become a web of intelligence. Science finally admits that the simple act of observing changes the result of any experiment and by extension, that the observer and the observed are not separate.

Quantum physics started in the late nineteenth century and is associated with the work of German physicist Max Planck. In the 1890's Planck set out to explain the phenomenon of blackbody radiation; the observation that the color of light emitted from an object did not change in a linear fashion to its temperature. Planck provided an explanation for the phenomenon in 1900 by postulating that light is emitted or absorbed in packets of definite size, which he called a quanta. Thus light, once considered a wave, was now being described as a particle (photon) in order to solve the riddle of blackbody radiation.

Quantum theory is also generally regarded as one of the most successful scientific theories ever formulated. But while the mathematical description of the quantum world allows the probabilities of experimental results to be calculated with a high degree of accuracy, there is no consensus on what it means in conceptual terms. The issues involved with this apparent conceptual conundrum are discussed in this article by David Pratt - Consciousness, Causality, and Quantum Physics.

According to physicist Leon Lederman there are three qualities we know about quantum theory.

1. It is counterintuitive,
2. It works,
3. It has problems.

Lederman goes on to write, "In spite of the great practical and intellectual success of quantum theory, we cannot be sure we know what the theory means." It is this ambiguity within the "hard" science of physics that has helped initiate a crisis unlike science has ever encountered. Once concerned with the motion and trajectory of particles, physics is now considering questions which would have been labeled as blasphemy throughout academic circles a hundred years ago. Now, numerous physicists are speculating about the nature of reality, the existence of consciousness, even the existence of God.

According to Pratt - According to the conventional interpretation of quantum physics not only is it impossible for us to measure a particle's position and momentum simultaneously with equal precision, a particle does not possess well-defined properties when it is not interacting with a measuring instrument. Furthermore, the uncertainty principle implies that a particle can never be at rest, but is subject to constant fluctuations even when no measurement is taking place, and these fluctuations are assumed to have no causes at all.

Simply speaking, the quantum world is believed to be characterized by absolute indeterminism, intrinsic ambiguity, and irreducible lawlessness. Most physicists are content to accept the assumption of absolute chance. This has important implications in connection with free will.

As the late physicist David Bohm (1984, p. 87) put it: "it is assumed that in any particular experiment, the precise result that will be obtained is completely arbitrary in the sense that it has no relationship whatever to anything else that exists in the world or that ever has existed."

It is widely accepted that consciousness or, more generally, mental activity is in some way correlated to the behavior of the material brain. Since quantum theory is the most fundamental theory of matter that is currently available, it is a legitimate question to ask whether quantum theory can help us to understand consciousness. Several approaches answering this question affirmatively, proposed in recent decades, have been surveyed in this excellent article - Quantum Approaches to Consciousness.

According to Mark Bancroft in Quantum Physics & Consciousness - "Quantum physics has directly challenged the meaning of matter for more than fifty years. Being defined as, "Something that occupies space and can be perceived by one or more senses; a physical body, a physical substance, or the universe as a whole.” Thus, matter may also mean the entire universe; including "'not-real' stuff". The atom was considered to be the indivisible building block of the universe up until the discovery of the electron. Now, particle physicists postulate that there are sixty-one elementary particles which make up all matter in the universe."

On a side track - Professor of Mathematical Physics, Frank Tipler, confidently proclaims that physics can and will lead to the immortality of humankind. He shares on page three of his book - The Physics of Immortality.

According to Dream Manifesto - Reality is never experienced on an exclusively personal level. The 21st century has witnessed the introduction of new ideas about how we fundamentally view reality. However, all we can know of the world in an absolute sense comes from our own sensory perceptions and the mental constructions we build around them. Behind these perceptions lies pure consciousness. Quantum physicists have shown that consciousness itself - something you have in infinite supply - is the basic stuff of the entire universe.

Quantum physics is a branch of physics which concerns itself with the study (observation) of the subatomic realm. Physics is defined as, "The science of matter and energy and of interactions between the two. Physical properties, interactions, processes, or laws. The study of the natural or material world and phenomenon." Being a scientific endeavor the above definition appears to fit with the somewhat vague definition of science.

A rather beautiful representation of quantum mechanics and consciousness is given on this website

And before I close this entry, I must mention Fred Alan Wolf who is a physicist, writer, and lecturer who earned his Ph.D. in theoretical physics at UCLA in 1963. He continues to write, lecture throughout the world, and conduct research on the relationship of quantum physics to consciousness. He is the National Book Award Winning author of taking the Quantum Leap. He is a member of the Martin Luther King, Jr. Collegium of Scholars. More can be found about him on this blog… of course he also has his own blog site J there are a thousand questions which clamor my mind and one day, I intend to ask Dr. Quantum…
