Time travel

Growing up I used to think a lot about time travel. It was both a mental escape and a complete fascination in the concept. I remember talking to my high school science teacher about travelling faster than light. I reasoned that everything we see is relative. If an object is closer to me than somebody else then I was seeing their future as thereflection of light from the object reached me before it reached them. And they were seeing my past. My teacher dismissed my query by saying these were Einstein’s theories. Pity, I had a lot more questions.

By the age of 18 I had invented a concept for time machine. Without going into all the detail it looked like a flying saucer which consisted of several layers of spinning shells, each layer was suspended in a vacuum and moved vast amounts of charge from the rim to the poles of the device. The theory was that although you cannot move an object through time and space you can move the space which defines an objects position in both time and space.

These days I am fairly certain that it wouldn’t work but I still think it may provide a way of travelling to any point in the universe instantly.

My belief in time travel has waned because of the paradoxes as well as the silly idea of alternate dimensions or time-lines.

For instance, if they invented time-travel anytime between now and the next million years then time travellers would be with us today. And considering how egotistic people are I sincerely doubt that one of these many tourist time travellers wouldn’t let slip he was from the future and try to warn us of our follies or some impending disaster and offer indelible proof. Stephen Hawking came to a similar conclusion. Let’s face it, people are far to egotistic, greedy and stupid to keep such a huge secret.

The other eternal problem is that of causality or paradoxes. The classic example of a problem involving causality is the “grandfather paradox“: what if one were to go back in time and kill one’s own grandfather before one’s father was conceived? All of a sudden you can’t possibly be there to kill him in the first place.

If you believe in alternate time-lines, parallel universesmultiverses or dimensions then it would mean that all the known physical laws governing the Conservation of Energy are wrong. It would mean that every split second wholealternative universes are being created purely on the basis of our individual decision-making. Think of the energy contained in one atom and multiply that by an infinite number of atoms multiplied by an infinite number of possible time-lines. Sounds a bit egocentric to me!

My theory on time is that all matter is fundamentally movement>pressure>density. Matter NEVER stays still so the matter or energy that existed a thousand is still here now, just in a different form. If that matter/energy remained frozen as “the past” then we would be in very serious trouble now. So the ‘yesterday’ as you remember it doesn’t exist outside a recorded impression in your mind.

Time is only a measure of relative movement. If there was only one thing, say a ball, moving in otherwise completely empty space at whatever speed you might imagine, it would have no past, present or future without another reference point. I could go on but suffice to say that time only exists as our consciousness of change.

I strongly believe that one day we will invent faster than light travel. Light is only a wave-form therefore may govern how we perceive the world but does not present a theoretical speed restriction.

But then again I might be completely wrong? the following is certainly a very impressive jargonistic write-up.



About Rob W Harrison
There is a part of my mind that stubbornly thinks about science. I have a life, job, wife and family but without my Van Der Graaf Generator life would be incomplete. I am a great believer that this amazing universe came into being through process: movement >pressure > density > mass. Maybe I believe in an non viscous ether. Anyway this is where I can share my thoughts.

    Faster than light is possible via OBE. Time Travel is not possible even with OBE. So highly unlikely inside of the space of description.

    The ultimate objective for anyone inside of the space of description is to find a way to leave description permanently!

    Live in a way so that one is not attached to life regardless whether it involves family, friends, career, or other curious adventures that come in the way of that goal. Try to remain dis-attached while still living in the world so that when the time comes, there are no attachments to tether one to the space of description.

    Remember, the space of description has a memory and will remember you if you ever traverse the space of description. So make that memory one of dis-attachment so that it does not attach itself to you!

    TT is a waste of time and resources!

  2. I like the way you think.
    Remember, if time travel will ever be possible, it already is…

    Okay, I am six years late, but I so much hate this so-called “grandfather paradox” that I will comment it.

    1) The paradox itself: someone uses a time-travel device, goes back in time and kills his grandfather; as a result he wasn’t born, and thus could not go back in time to kill his grandfather, so he was indeed born, etc., etc.

    There is just a huge flaw with this: either the universe is predetermined or undetermined, but not both. Someone who travels back in time only proves that the universe is 100% pre-determined. Because when he reaches the grandfather’s epoch, both his past and future are already written. So, time travel is not impossible because of paradoxes, time travel only proves that everything is already written, and therefore one could travel back in time not because he decides so, but because he was fated to do it, and while doing it he just doesn’t create any such paradox.

    2) Stemming from quantum physics, relativity, etc., some scientists think that time doesn’t exist (i.e.: it’s not a linear thing). Everything (all time) exists simultaneously, but not as parallel physical universes, but as potentialities. As a result not only the future is undetermined, but the past too. So despite there is inertia of some sort (i.e.: a probable future), future could be changed, and in doing so it also changes the past (likewise modifying our memories). It sounds silly, but only as far as we remained convinced about matter being the basis of our universe, where new thories lean toward the idea is that information is the basis of our universe.
