Multiverse theory (parallel universes)

According to quantum physics, if time travel is possible then parallel universes are possible. Quantum physicist have come up with a "multi worlds" hypothesis.

It goes something like this:

1) Today I make a choice that affects who I am for the rest of my life. Say perhaps I choose to accept a job offer. As a result I meet certain people, develop certain relationships, maybe even marry a certain person.  My life takes a certain path based upon one decision. This could be thought of as a fork in the road. Whether I eat lasagna for dinner tonight is not really such a big decision.

2) Perhaps I go back in time ten years from now, or perhaps my son goes back in time and convinces me not to take the job. From that point onwards in my life a different path is taken. When my son returns to his time, nothing will have changed there though, I would still have chosen the same job, and he would still have been born.  BUT- a new parallel universe is created where I take a different job, meet different people, maybe even marry a different person, or perhaps still end up marrying the same person.

Some argue that there are an infinite number of parallel universes. I don't quite agree with this. In quantum physics there are an infinite number of possibilities until an observation is made, with all of those possibilities collapsing back into one resulting reality.

I argue that a parallel universe can only exist IF and when time travel has occurred and IF and when a different decision is made at an important forking point. In such a scenario, if time travel has occurred multiple times, there are multiple parallel universes (based upon different dichotomous decisions), but still not an infinite number.

In the same way that an electron can be in more than one place at the same time (yet not being two electrons and not being two halves of one electron; --> see the "double slit experiment"), a person in two or more different parallel universes is the same person not different people. This means that even if there are multiple versions of the same person, ultimately they are still one person. In my opinion this person would be the one person before God.

In fact if one such version of a person tried to jump across from one parallel universe to the next the very act of observation would collapse the other parallel universe that person left behind, making the new parallel universe the reality.

This image goes some way to explaining the various paths a person can take. Many different choices can be made, but the more that are made the thicker the bunch of lines together will be, until there is just one thicker bunch of lines, one over all uniting identity and reality for a person.

I had previously thought I did not believe in parallel universes. My logic went something like this:

1) Apparently there are an infinite number of parallel universes.

2) If that is the case then there would have to be one where Jesus chose not to go to the cross.

3) This possibility could not be so, Jesus would not have done such a thing.

4) Therefore there can not be parallel universes.

Now I think differently:

1) There can be parallel universes, but each of them exist as a result of time travel.

2) There are not an infinite number, but only as many as have been spawned my time traveling choices.

3) Each of these parallel universes still collapse into the one, just as the electron collapses into one upon observation in the double slit experiment.

Is time travel possible? (Einstein, Mallett and the Large Hadron Collider)

I wrote very briefly back in 2006 that I think time travel is possible. I have always believed that time travel is possible. What I have not known is whether it could come about in my life time or not. I have never gone into this deeply on my blog, mostly because people do not like to entertain this topic. Some of my recent reading has led me to realise that it is an area of physics that is now being seriously researched. Finally I can begin to explore this topic.

Einstein's theories prove time travel forward is possible
Einstein opened up the possibility of time travel being a serious scientific concept through his two theories: the general theory of relativity and the special theory of relativity. The special theory of relativity says that when an object travels fast enough time slows down.

I.e  Repeated experiments have shown the following:
- An atomic clock was placed on a jet plane.
- A corresponding atomic clock was placed on the ground, with exactly the same time.
- The jet plane flew in the sky at a speed approaching sound.
- When the plane landed, its clock was fractionally behind the clock on the ground.

As mentioned, this experiment has been carried out many times. There was nothing wrong with the clocks. This experiment was carried out by physicists seeking to prove Einstein's special theory of relativity. The pilot on those flights had actually jumped forward in time, although only by a very small amount.
Travel at much faster speeds would allow the traveler to jump even further forward in time. Consider a space ship that traveled out into space at close to the speed of light. Traveling at that speed for a journey of two years and back would occur while over 200 years passed on earth. This is based on exactly the same theory as the jet plane and atomic clock experiment. This a widely accepted theory in physics that says that it is possible to jump forward in time.

There is another method of jumping forward in time that is theoretically possible. Black holes can bend space and time, allowing a jump forward or back in time. Black holes could of course tear part what ever objects traveled through them.
Another method again is a worm hole. A worm hole is currently theoretical, but it connects two different places of space and time.

Building a time machine employing the physics of a black hole would require the ability to manipulate the energy of an entire star. So it is still very theoretical.

What ever the case, it must first be established that time travel forward has already been proven as theoretically possible.

Examples of time travel in every day life

I am sitting on the couch here typing my blog on the laptop. My son is currently sitting in another room playing with his toys. I can see him and hear him, yet he is actually in the past. The light traveling from him and the sound traveling from him take time to get to me. All people around us are actually in a different frame of time to our own.
Another example comes from the form of videos and photos. We are capable of watching past events that have been recorded on film or video. This would not be possible if the machine (video camera) that captures these past events had not yet been made. This means, that it is impossible for us to view events before the camera had been invented. The camera does give us a glimpse into the past, a sort of time travel for the brain.

Backwards time travel has always been refuted
Many have argued that although it is theoretically possible to travel forwards in time at great leaps, that it is impossible to travel backwards in time. There is however a modern physicist whose research questions this very notion. His name is Dr. Ronald Mallett, and he is a professor of physics at the University of Connecticut. He has an interesting story. His research boiled down says that gravity can affect time (as in a black hole), and that light can affect gravity. His research has been in black holes and lasers for much of his career. His theory is that light by affecting gravity, can affect time.

Mallett explains that light can make space swirl around, in the same way that a teaspoon can stir water in a coffee cup. If a cube of sugar is thrown into the swirling coffee it can be observed swirling around. In the same way a particle thrown into swirling space can also be observed.
Mallett theorises, that when such a machine is built it will be possible to send particles back in time, but only to any point when the machine is already switched on. I.e If it were switched on today, December 15h, 2011, then from any point in the future a particle could be sent back to today or any day after today. A particle could not be sent back to December 14th or any earlier day. This is much the same as the fact that film can not be made before the date that the camera was invented.

If Mallett successfully makes his time machine, we will not be able to travel in time as people, but it will be a significant leap in the theory of time travel.

The Large Hadron Collider in Switzerland.

The Large Hadron Collider is a large underground tunnel 27 km in circumference, not unlike a synchrotron. Its designed purpose is to collide protons and other sub atomic particles with one another. It is hoped that many things will be discovered about the nature of sub atomic particles. Further than that it is hoped that layers below the sub-atomic such as the existence of a Higgs-boson particle can either be proven or disproven. It is also hoped that the nature of dark matter can be understood through experiments.
All of these experiments will no doubt bring far greater understanding to the nature of physics, giving greater context to the concept of time travel.
Before the collider was switched on there were some people who tried to take out legal injunctions against its procession. They claimed that the experiments could open up black holes that could suck the earth up. It is true that experiments at the collider could indeed create black holes, but none with any sufficient power to suck the earth up. It has also been postulated that the experiments could open up tiny worm holes.
And now for the slightly tongue in cheek question. Are they actually building a time machine at CERN in Switzerland?
(For now I am happy to take all experiments as above board. But I do find it uncanny that the Large Hadron Collider is capable of sending protons at "3 metres per second less than the speed of light." This sounds potentially like a very large model of what Dr. Ronald Mallett is currently attempting to build.)

It is actually possible that activities at the Large Hadron Collider could be paving the way for time travel to occur, by the creation of worm holes, or at the very least by a far deeper understanding of physics.

Conclusions
The physics is there to theoretically prove that time travel is possible. Personally I get excited by this stuff. The practicality for people to time travel could still be a long way off. The possibility of sending particles through time may not be far away. It may even be possible to send messages through time.
For someone to travel backwards in time, there would have to already be a working time machine on the date in the past. Therefore if someone claims today that they are a time traveler the easiest way to test this is to see their time machine.
The possible existence of wormholes however could contradict the theory that a time machine must be present in the past. It may simply be possible to travel through a worm hole. It may not be possible however to choose where and when these worm holes go, and if it is possible to return.

Mars Rover "Spirit" and Titan probe "Huygens"- both instruments of worship.

Over the last couple days we have watched a couple of space exploration documentaries. The first was called "Death of a Mars Rover", produced by National Geographic. The second was "Destination Titan", produced by the BBC.

I am always fascinated by space exploration. I have the greatest admiration for the scientists who are involved in these endeavours. Some may think that their activities are a waste of time and that they are of "no earthly good." Nothing could of course be further from the truth.

It is an easy temptation for humanity to be short sighted. Much like in Christianity, people get focused solely on the salvation of the individual and do not stop to realise that God's purposes go way beyond salvation. God's purposes are to establish his eternal kingdom. Salvation is just like getting the citizenship certificate, to say nothing of the civil responsibilities, as well as dreams and aspirations of the King and his citizens.

In a similar way many people do not realise the value of exploring the universe. But I can think of few things of greater value. Space exploration has intrinsic value in itself. We have a duty to understand the universe around us. We have a duty to explore it. In fact this can even be worship. To learn more about God's universe is to glorify him for creating it. For this reason I have the greatest admiration for the scientists who work to explore the solar system and the universe- even if they don't agree with my premise.

Of course there could be far more practical reasons for space exploration. There are undoubtedly many minerals available in our solar system that could be used on earth and to further our exploration. But until we discover minerals that are in low supply on earth (or even non-existent on earth), space mining is on indefinite delay. There can be no doubting that commercial incentives would push space exploration at a rapid pace. Sometimes I feel that this is needed, as on the whole space exploration is moving quite slowly. I still find it a shame that a base has not yet been established on the moon. Science just doesn't seem to be a big enough motivator for the general public, although it is a very worthy cause.

In the two documentaries, remarkable stories were told of success against improbable odds. The Mars rovers were supposed to only last 90 days. But one of them lasted seven years, and the other is still going. Even the stories of their survival, for me are a clue that God is in favour and support of these scientific missions. I can hear God saying, "sure, explore as much as you can, I know you are looking for life in the universe and I know you don't want to be alone on earth, so keep looking, the more you look and the more you search, the more likely you are to find ME." I can hear God cheering along the endeavours to explore Mars and Titan.

The probe that was sent to Titan (in 1997) nearly did not make it. And it even came down to the last three minutes of energy on the probe for it to collect that data that was planned. Success came down to the last second. Now scientists are hoping to send a "boat like probe" to sail the seas of liquid methane on Titan.

I remember watching a documentary on what earth would be like 10 000 years after the last human was gone. It was speculated that perhaps Mt Rushmore would be the last remaining evidence of humans. All other structures would have disintegrated and disappeared. What would someone think if they found Mt Rushmore's presidential tribute? It would have the same unexplained aura as does Easter Island or Stone henge. What does it say about our world?  Perhaps it even says that America worships it's presidents.

But then it has been mentioned that the Mars Rovers will not decay as there is nothing to cause their decay, and that they will likely remain as they are for millions of years if no one goes to Mars. I think it is  a far better testament to humanity to see us exploring the universe, than leaving marks of worship to presidents carved in mountains.

A ranch on Mars

So it looks like I may have left my sports research phase behind me. (Time will tell). I spent a lot of time researching the history of football codes, and then I discovered a sports opinion blog called The Roar. I seem to have spent an inordinate amount of time writing comments and articles at that blog, and my own blogging slowed down a bit as a result. In the end I got a bit ticked off by some of the people who continued to claim that soccer is the best sport, and as such were not a lot of fun to debate with. It started to feel like the debates were going around in circles. So, it's time to spend my brain space on other things.

A friend may have just rescued me from my football induced stupor when he asked me if I had heard about the Phoenix probe that has just landed on Mars. I had heard of it, but I nearly ignored it, which is so unlike me.

I still have lots of reading to do to catch up on the goals of the probe. Exploration of Mars fascinates me, because I see it as part of God's plan and gift of the universe to us. Imagine if sin had never entered the world. Imagine where we would be today. No wars, no death. Technology would have advanced far into space by now. Nevertheless, this does mot mean that the wonders of space are not for us now.

I like to think that Mars and the other planets are there for us to use as resources. There is bound to be a lot of mineral wealth in space, say for instance in the asteroid belt, which is between Mars and Jupiter.

The Phoenix probe landed on Mars on May 25th. It landed near one of the poles to search for ice. The purpose of the project is to research the history of water on Mars, to get an idea of climate change there and whether life may have possibly existed there.

The probe landed in a very specific spot, which is quite amazing in itself. The level of science needed to send this probe is staggering. The probe is digging into the Martian soil. Information is being sent back to earth via the martian satellites which then beam messages to earth's sattelites.

Such sophisiticated technology leads me to imagine future possiblities. The temperatures by the poles can get as low as -80 C over night, which is a little too cold for human habitation. Temperatures at the equator however can get up to +27 C. So human habitation would be possible by the equator but not by the poles. (At least in the early stages). Robots however could travel to the poles and even build roads to the poles to mine water. In fact much of this could even happen before humans ever set foot on Mars. Indeed the fact that two satellites already orbit Mars and send communications back to earth are actually the beginnings of human infrastructure on Mars.

It may still be a generation or two before humans set up a colony on Mars. I guess we need to set up a colony on the moon first to make this possible.

End of the world just round the corner?

Well I think I have painstakingly explained previously why I think the end of the world is a long way off. But there has been some interesting news this week to make the hair stand up on the back of your neck. I was reading theage.com.au and stumbled on this article "World's largest experiment set to go off with a big bang."
It is about the world's largest particle accelerator underground in Switzerland. The experiment is scheduled for July, when two atoms are set to collide at a speed just short of light. The temperature created will be 100 000 times hotter than the centre of the sun. (That's a figure that is completely academic to me.) It is hoped that the experiment will create matter and anti-matter previously unobserved. This of course is quite fascinating. It is hoped that analysis of the new matter created will give clues about the big bang.
There are some environmentalists from Hawaii (not physicists) who are afraid that the experiment will create a black hole that will suck up all life on the planet. They have attempted to legally stop the experiment from going ahead. I tend to think that their fears are completely unfounded.

But you never know, perhaps they are on to something along with the cult that just came out of the cave in European Russia. Perhaps if the Hawaiian environmentalists ask really nicely the Russians will let them join their cult.
