Five Major Problems with Wormholes

Five Major Problems with Wormholes 

Wormholes are supposed to be shortcuts from one time and place to another time and place.   For example, drive your spaceship into one end and exit near some other star, perhaps 1000 light years away.   Drive back through and return to earth.  Simple enough.

If a wormhole is ever created for passage of man or machine by some future civilization, then there will be some major problems to overcome other than the biggie… creating the wormhole in the first place.  I believe this is the first time most, if not all, of these problems have been identified.  

Although the wormhole supposedly bends/warps time and space, there is a fundamental limit to how fast you can get from here to there, no matter how much time and space are warped.   That limit is c and it applies to the Long Way Around (LWA) path length.  First let me tell you why I think so as it is key to the some of the rest of my list of problems.  

A common wormhole is created by every photon that exists.   For example, a photon does a space/time warp from Proxima Centauri (the nearest star to our sun) to our eye.  The distance and time the photon experiences is zero.  It does not age during the trip and the total distance is zero at the moment of creation.   However, it still takes 4.22 years to get here, the time light takes to travel the total distance from that star to ours.     

Einstein’s equations say that the photon traveling at c has a total path length of zero and travel time of zero duration.  I believe that applies to every photon.   However, we know that the photon takes 4.22 light years and travels about 28 trillion miles from that star to our eye as we measure or calculate it.   Even though the path the photon sees is zero length and the time it ages is zero time during the trip, it still does not arrive until the entire 4.22 light years elapses.  

It is my theory that this is because the space/time warp of our photon wormhole connects the emission point on Proxima Centauri and the landing point in our eye only in a virtual sense and only in the first instant of its creation.   

After that first instance, the photon moves away from the emitter at light speed and the path behind it expands as the photon travels along it at c.   The photon’s path to our eye always remains zero length, but it traverses the path at c, leaving an expanded path behind until the entire path is traversed.   The photon never transfers its energy until the entire path is completed at the maximum velocity of c.   

My first wormhole problem is that the time required is no less than the long way around travel time at c.   Anything entering the wormhole is imposibly close to the other end (as for our photon example), but cannot actually get there until the path from the entry point expands behind the object moving at c throughout the entire trip, the LWA, just as it does for the photon wormhole.  

Even if the wormhole spans a time/space warp of 1000 light years, it will still take no less than 1000 years to get from here to there even if the wormhole appears to be of zero length.   The crew of the space ship that manages to get into a wormhole would not age during the trip, a distinct advantage for the crew and the ship’s lifetime.  It would seem to be instantaneous and if it were indeed reversible, then the return trip would be just as fast.  Drive into one end and return immediately and likely not be but a few hours older.   However any companions that were left behind on earth would be dead nearly 2000 years.   All this assumes the problems that follow can be solved.

The second problem is that a wormhole cannot be established before it is created at each end.  If  one end is created today and the other is somehow created on a distant star, the wormhole would not be operable until the second wormhole is created, presumably at least the normal space ship travel time from one construction site to the other, even if the construction crew travels at c.    Unless the wormhole acts like a reversible time machine, a much more difficult arrangement, it will take the same amount of time each way through the wormhole with the arrow of time aging both ways and it cannot begin to be used as a shortcut until both ends are finished.    It would take a very patient civilization to plan for such a feat.

My third problem involves getting into any wormhole that moves you along at light speed.  The nose of the ship would presumably be accelerated to light speed even before the crew compartment made it into the opening.   The result would be powdered spaceship and crew with photons leading the way, larger particles and atoms dragging behind, but no survivors or anything recognizable.  

The fourth problem is getting out of the wormhole.  Let’s say somehow you can get your space ship in and up to speed.   Everything going out the other end arrives there at light speed.   A huge blast of various rays and light burping out the other end, frying anything loitering near the exit.  A great light show, but hardly useful for the crew wanting to get from here to there in a hurry, or their greeting party for that matter.  The wormhole turns out to be a great ray gun! 

My fifth problem involves reversibility.  We assume that entering the wormhole at either end establishes the direction of travel.  However, it appears to me that it is very likely that the arrow of time exists only in the direction of the creation of the wormholes.  That is, from the first wormhole to the second.  Items entering the first one created would be moving in an arrow of time from the earliest time to the latest.   Items trying to enter the second wormhole to come back would be rejected in a smoldering heap or blast of rays.   If that logic is reversed, the problem still exists:  One way only!

Arrow of Time Established? 

I believe this applies to photons and particles in general.  The equations for physics always seem to allow collisions to be reversable and there are no laws that would not allow any set of particle interactions to be reversible.   However, it is my opinion that photons are not reversible for the reasons listed above.  They are zipping through non reversible wormholes.   Energy is transferred from point of creation to some other point where it is absorbed or transferred to another particle and can’t go back though the wormhole as it is a one way street, from first end created to the second end and never the other way around.  That means the arrow of time always moves forward and is never reverseable.  It can be stopped but never reversed.

SuperLumal Transmission?

As a side note, for the reasons listed in the problems listed above, there will be no speedup of communications through a wormhole.  No superlumal transmissions, no advantage over sending it across space the normal way, and very likely, no two way communications.   I hope these revelations do not stop any projects in progress as science will advance no matter what.  8>)  Photon wormholes are the best anyone will be able to do.
