Sounds like someone came up with their own theory of wormholes, and then proved it useless.
I'll highlite a couple of details:
A common wormhole is created by every photon that exists
I see no sence in this assumption.
I suspect the reasoning goes something like:
"wormholes let you travel fast" and "photons travel fast" -> "photons travel through wormholes"
in which case it's flawed logic. If the
assumption has other reason, I'm not sure I want to know them.
Anyways, photon (and it traveling at the speed of light) can be deducted as a solution of Maxwell's equations in flat space, so there are no wormholes involved.
My first wormhole problem is that the time required is no less than the long way around travel time at c
[...]
path from the entry point expands behind the object moving at c throughout the entire trip, the LWA
This sounds like confusing the concepts of wormhole and warpdrive.
And/or assuming that the length of the inside of the wormhole is the same as the length of the "long way" path, thus completly ignoring the picture he included at the top of the article, where the wormhole way is quite obviously at least 3 times shorter.
The second problem is that a wormhole cannot be established before it is created at each end.
Okay. I could buy that, physics-wise.
But the author seems to implicate it means the technology would be useless, while I think it's good enough.
If you could just build wormholes at will, then you could just send unmanned probes to cover the galaxy in a network of wormholes.
It would take some millenia, but if you have the technology, and nothing else to do with your time...
I've read a comic with a similar theme- planet robbing space pirates would broadcast plans for wormhole creator, then pillage any planet that build one.
Anyways, this "problem" highlites another inconsistency in the article...
If "A common wormhole is created by every photon that exists", and "wormhole cannot be established before it is created at each end", then that means the photons emited from AlphaCentauri had their wormholes created 4 years ago (or else they couldn't use them back then when they were emited...), and the wormhole-exits would be pointed precisely at the place where my eye intercepts them now... or something like that?
Just imagine, if there was a way to detect these wormholes, it would mean INSTANT superluminal communication!
It also means that 4 years ago, the exact position of molecules in my eyes was known... to the photons launching at AlphaCentauri...

omg, don't bother with superluminal communication, if you could examine the starting ends of wormholes, you would literaly
see the future.
My third problem involves getting into any wormhole that moves you along at light speed,
Why would the wormhole move you along at light speed?...
Is that because "photons move through wormholes at the speed of light"? Even more backwards logic.
However, in a manner speaking this complaint has some merit. The enterance to a wormhole
would be a gravity well similar to a blackhole. If it's too small you would get torn by tidal forces. And even if you got in, there's no way to escape black hole. I think there is a way around that... but it requires some exotic matter or negative energy, which aren't easy to get...
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 sentence has no meaning I can see. "Arrow of time" is something that differentiates future and past. eg. a dropped glass breaks if you go forward in time - pieces of glass merge if you go backward in time, so glass breaking is an arrow of time.
He probably meant that his mechanism for accelerating you to speed of light as you enter the wormhole only works one way. But it's completly unclear why would it be so.
And if it does? Well, then you could just build two wormholes, one next to another, going opposite directions
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.
LOL?
Anyways, the main, and fundamental problem is that if it was possible to travel faster than light at will, then it would be possible to travel back in time, at will.
