# 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.

## Does Time Exist?

There is no question that we experience what we call time.   There is a precision with which we can measure the progression of events over time that is phenomenally accurate.   Things age and particles decay over “time” and it is consistent.    However, physical laws that use time as a reference work equally well for time reversal – going backward – a particle hitting another particle, generating other particles and emitting photons will work just as well running backward according to physics.   We just have never experienced time reversal and this disconnect with the laws of physics seems to be a mystery.  This disconnect is used by many to express the opinion that time exists.   However the fact remains that equations of space and time break down at certain points and time falls out of some of them as an unnecessary factor.

Think of this: photons live in “null” time.  They live and die in the same instant because they travel at the speed of light and therefore if time exists for them, they do not experience it.   They experience zero flight time over zero distance no matter how far apart the start and finish line are.  They live in a go-splat world.    A photon leaving a star a billion light years away destroys itself in our eye the instant it is emitted, having not aged even a fraction of a nanosecond in its long trip.   Space and time are that warped!

The space and the time have been warped because of the speed of the photon.  It travels at the speed of light.   Our very definition of speed involves time so when we say the speed of light we assume that time exists, but for the photon time does not exist.

A photon experiences zero distance and zero time due to its incredible speed.   Every photon that lights our office or illuminates our book arrives the instant it is emitted.  It has not aged even though we can calculate that it moved from the bulb to our book and then to our eye at about one nanosecond per foot of travel.  The photon did not experience the “time” that we measure or calculate.  It aged not at all.  Time does not exist for any particle moving at c.  It only exists for us as calculated or measured in a laboratory.  But does it exist as a real dimension?  Does it have a physical basis?

A photon in flight between point a and point b is invisible to any and all observers.  It does not exist in flight and can only be detected at b when it actually arrives.   The photon in flight experiences null time – time zero – no time – non-existent time, and travels a null path – or no path at all, regardless of the length of its travel.   Time for the photon does not exist, nor does distance.  Those measurements of time and distance for the photon are for our domain only – the human one.

Now consider an extension of that thought – most of the particles that make up our world vibrate and exchange energy with each other.  That occurs even at temperatures close to zero.   There is also a froth of virtual particles that pop into and out of existence continually at all times even in a so-called perfect vacuum.     All the energy exchanged through photons is timeless because all photons are moving at c.   Even gravity moves at c.  Gravity is also timeless within its self.   The exception is for atoms that bump into each other and exchange energy through vibration and bumping.   Or do they?   Do they actually touch or isn’t there an exchange of particles  moving at c that keep them apart?

If the energy transfer by photons is timeless, the photons are timeless, gravity is timeless all due to the speed of light as experienced by the particles that carry them, then does time exist or are we merely measuring external events by counting uniform progressions that we experience and can see?

I know and acknowledge that we can measure the speed of a photon to a very high precision.  I know that we can measure the speed of gravity as other planets tug on ours and on each other.    The measurement is based on the progression of the components of our clocks.   We do live in a dimension that experiences progression of events in one direction which we call time.

However, we can measure but we cannot see.  We can observe the effects but not the event.   The truth is that whenever something is traveling at c, simultaneous observations are impossible.  Every observer of the same event sees something different.    Have you ever seen time?  Maybe the change in a clock, which is actually only a measure of repetitive events, whether a wind up (measuring escapement events) or a NBS clock counting cycles of an atomic nature, but not timeWe can’t see time, only experience it.  We can’t measure time, only define it.

Time for us may be just a projection of ourselves on a line defined by a progression of events that occur in a uniform manner, but it may not really exist.    We are bundles of energy made up of atoms and particles in extraordinarily rapid motion.  Take us down to the quantum world and we are made up of many quadrillions of particles exchanging energy among themselves in mostly empty space.    In such huge numbers there is an average motion and an average progression of events that may make up our concept of time.  Certainly our most accurate “clocks” are merely counting cycles of an atomic nature.   Even the National Bureau of Standards admit they are “not measuring time, but only defining it“.

Does time exist just for us because we experience this progression in a uniform manner? Perhaps it is not actually an extra dimension as we have been so often told.

Do you think time exists as a dimension in the same manner as x, y, z?  Is time real?  If you have been following my last two posts, you will understand it is the lack of time, at least on the photon level, that explains quantum weirdness.   And explains it well.

What do you think?
