Travelling Through Time

Time travel has been the staple of science fiction novels, television programs and major motion ever since H.G. Wells first penned his classic prototypical scientific romance “The Time Machine” in 1895.

However, when time travel appears in Sci-Fi there is usually very little description of how the time machine actually works or the science underlying the principles of its operation. In reality there is a scientific basis to the notion of voyaging through time and it is firmly rooted in the physics of both special and general relativity as revealed by Albert Einstein in the miracle year of 1905 and during the war torn year of 1915.

In pervious postings in Discovery Enterprise we have presented the work of American physicist Ron Mallet and others who have been inspired by Einstein’s work to look at the possibility of time travel as a serious proposition.

Einstein revealed to us that the space-time continuum, in which our universe is embedded, is malleable and that both space and time may be interchangeable physical structures.

In today’s instalment of the acclaimed documentary series “Sci Fi Science” host Dr. Michio Kaku, a theoretical physicist by profession and Sci Fi fan at heart, looks at the possibility of taking the seemingly impossible physics of time travel out of the realm of science fiction and into dominion of scientific and technological reality.

The Universe – Time Travel

Today on Discovery Enterprise we present the fourth episode of the fifth season of the highly acclaimed documentary series “The Universe” currently airing on the History Channel.

The latest instalment of the series looks at the possibility of time travel and how it could one day become a reality.

Einstein’s theories of special and general relativity both allow for the possibility of travelling through time. Travelling into the far distant future is a definite certainty within special relativity. All you need to do is travel very fast at speeds that are a significant fraction of light speed and time slows down for you. This relativistic effect is known as time dilation.

This effect is a well established fact and has already been proven experimentally here on Earth and in space.

One only has to look at the behaviour of a short lived subatomic particle known the muon. A muon only has a lifetime measured in microseconds (μs).

If one comparers the lifetimes of two muons at different speeds we see some very surprising results. In the laboratory, slow muons are produced, and in the atmosphere very fast moving muons are made when cosmic rays bombard atoms in the tenuous upper atmosphere that exists on the very fridges of outer space above the Earth’s surface.

A muon’s lifetime at rest in the laboratory is 2.22 μs, the lifetime of a cosmic ray produced muon travelling at ninety-eight percent of the speed of light is about five times longer, in perfect agreement with calculations made using the theory of special relativity.

In this experiment the “clock” is the time taken by processes leading to muon decay, and these processes take place in the moving muon at its own “clock rate”, which is much slower than the laboratory clock.

Time dilation would make it possible for passengers in a fast moving space vehicle to travel further into the future while aging very little; since their great speed slows down the rate of passage of on-board their spaceship.

Thus the very first astronauts who venture forth to the stars will also be the first bona fide time travellers.

Yet, even more bizarre would be the mind-boggling paradoxes that would arise if travelling to the past ever became possible.

Carl Sagan’s Cosmos – Travels in Space and Time

Today on Discovery Enterprise we present the eighth episode of Carl Sagan’s highly acclaimed PBS documentary series – Cosmos: Travels in Space and Time.

In this instalment of Cosmos we follow Dr. Sagan on an odyssey through time and space and witness how star patterns change over millions of years followed by a journey to the planets of other stars, and a look at the possibility of time travel.

This takes us to Italy, where a young Albert Einstein first wondered what it would be like to ride on a beam of light.

Through The Wormhole – Is Time Travel Possible?

Filed under: Alex Michael Bonnici,Morgan Freeman,Through the Wormhole,Time Travel — ralphbuttigieg @ 7:05 am

Today on Discovery Enterprise we present the third episode of a new documentary series that premiered on the Science Channel in the United States on Wednesday June 9th entitled “Through the Wormhole” and hosted by veteran actor Morgan Freeman.

In the third installment of this exciting new series we explore the exciting possibility of travelling through the fourth dimension of time and take an odyssey into the deep distant past and into far-flung futurity.

Einstein’s Theory of Relativity says that time travel is perfectly possible — if you’re going forward. Finding a way to travel backwards requires breaking the speed of light, which so far seems impossible. But now, strange-but-true phenomena such as quantum nonlocality, where particles instantly teleport across vast distances, may give us a way to make the dream of traveling back and forth through time a reality.

Step into a time machine and rewrite history, bring loved ones back to life, control our destinies. But if we succeed, what are the consequences of such freedom? Will we get trapped in a plethora of paradoxes and multiple universes that will destroy the fabric of the universe?

The New Time Lords

Is time travel possible? And if it were what will this reveal to us about the fundamental nature of reality? Will our forays into the fourth dimension reveal to us that all of cosmic existence is in fact virtual and that we are nothing more than mere virtual players in a highly advanced computer simulation? Will our attempts at becoming the New Time Lords only reveal to us that in fact we are mere pawns in a highly sophisticated arcade game?

According to the BBC documentary Horizon-“Time Trip” such possibilities are very real.

Personally I feel that many of the off the wall arguments presented in this episode of Horizon are very good examples of pathologically bad science. I personally feel that in our attempts to stretch the limits of human knowledge to the breaking point we are in fact being led down avenues of muddled headed thinking and in the process science fiction and fantasy are taking the place of real level headed science.

I would very much welcome the comments and observations of my dear readers in our forums page.

The Universe – Unexplained Mysteries

Join us today on Discovery Enterprise as we ponder some the unexplained questions and mysteries of our cosmos.

We will delve into some of the myths, misconceptions, truths and amazing mysteries of our unique universe. Could life exist on Mars? Is time travel possible and does Einstein’s theory of relativity support it? Is there a companion dark star to our sun and could it pose a threat to earth? Learn about the spark that lit the big bang. Take a journey from science fiction that predicted all these things, to the scientific reality of what they mean to us in the ever-changing universe.

These are just some of unexplained mysteries just begging to be explored and understood, and so long as there are inquisitive minds, the unexplained can one day be made explicable.

Down the Cosmic Rabbit Hole: Voyages to Elsewheres and Elsewhens

Filed under: Alex Michael Bonnici,Black Holes,Parallel Universes,Time Travel,Wormholes — ralphbuttigieg @ 11:32 am
While I was growing up in the 1970s a new idea in Astrophysics had just come into vogue. The notion that the very fabric of our universe, the space-time continuum, can be ripped apart and be torn asunder to reveal portals that can take us to other parts of our universe or even other universes separate from our own. We were introduced to various new exotic celestial denizens that occupied this Cosmos along side planets, stars and galaxies the likes of which we had never heard of before – Black Holes, White Holes and Wormholes long before Michio Kaku became a household name..

I still have fond memories of reading books in my early adolescence with such thought provoking and imagination stirring titles as “Black Holes and Warped Spacetime” by William J. Kaufmann, “The Iron Sun: Crossing the Universe Through Black Holes” and “The Next Ten Thousand Years” by Adrian Berry all of which introduced the notion that cosmic portals exist that can take us on far off trips to elsewhere and elsewhens in our cosmos and beyond.

Today the notion of voyaging through such cosmic gateways that can zip you across vast distances in the twinkle of an eye or take you on voyages to parallel universes or on journeys across vast eons of time are the mainstays of twenty first century physics. It is almost as if the Physics of the twenty-second century of Star Trek has arrived a century earlier than expected.

So join us on Discovery Enterprise as prepare to take a trip down the cosmic rabbit hole into the wonderland of twenty-first century physics as we voyage to other universes and take a journey through eons of time.

The Universe – Cosmic Holes

Our infinite Universe is brimming with strange, violent and positional life transporting phenomena. Imagine cosmic portals where objects could disappear, be ejected or escape to some other place in space or time. We are about to take a voyage through a cosmic portal on an infinite voyage.

The Universe – Parallel Universes

Some of the world’s leading physicists believe they have found startling new evidence showing the existence of universes other than our own. One possibility is that the universe is so vast that an exact replica of our solar system, our planet and ourselves exists many times over. These Doppelganger Universes exist within our own Universe; in what scientist now call “The Multiverse.” If proof is found it will change our lives, our minds, our planet, our science and our universe.

“You’re travelling through another dimension — a dimension not only of sight and sound but of mind. A journey into a wondrous land whose boundaries are that of imagination. That’s a signpost up ahead: your next stop: the Twilight Zone”!
– Rod Serling

Horizon: The Time Lords

Horizon investigates the physics of wormholes and the limitations physics places on the possibility of time travel.
