EM Drive To Receive Peer Review

It is proposed that CDM axions were created in the Big Bang but not from photon decay. Strong magnetic fields should be able to convert axions to photons and possibly vice versa, which should render them detectable. The existence of axions might also help solve the strong CP problem.

Photon decay in our frame of reference being at least partially responsible for dark matter would seem to imply a far, far greater age to the observable universe, which belies the CMB data.

The question is this. Is the Universe expanding because of the outward force of light photons emanating from all of the suns in the Universe creating enough force against the Edge to actually force the Edge away?

Everything ends in Ginnungagap. Then the forces of Niflheim and Muspelheim will begin a new cycle. This has all happened before.
 
They are all one in Yog-Sothoth. Yog-Sothoth knows the gate. Yog-Sothoth is the gate. Yog-Sothoth is the key and guardian of the gate. Past, present, future, all are one in Yog-Sothoth.
 
So what you are saying Gov, is that there is a gate at the edge of the universe, and it is its own guardian and key? Hmm. . . does that make the universe a kind of Klein bottle?
 
That's actually an interesting question to which someone has provided an answer:

It would likely have to be a 3-D or higher dimension analogue of a Klein bottle, which is a 2-D surface embedded in a 3-D space:

Since the Universe does not appear to be non-orientable, it seems that it isn't so shaped. For example, right-handed neutrinos and left-handed antineutrinos are not detected:

Even if the universe is finite but boundless it still means you are still the "center" anywhere you go.

Now, at some point all the matter was in the monobloc ("cosmic egg') but if space outran matter, then that means the explosion did have some initial shape. If not, the supervoid might still be thought of as a good arbitrary "center "--rather like how the Prime Meridian intersects with the equator at 0 lat, 0 long' (good place for a space elevator too perhaps.
 
One current theory is eternal inflation as there's really no apparent reason why the inflaton field should ever turn off completely in all regions. The result is an infinite multiverse, which is likely fractal in nature with new universes constantly being created. It has been suggested that some large scale features of the CMB and anomalous galactic motions might be due to interactions with neighbouring universes.

In 2003, its was proposed that the shape of the CMB curve at large angular scales could be explained explained by a dodecahedral-shaped Universe where opposite faces meet to form a sort of "cosmic hall of mirrors".

However:
As of 2016, the publication of data analysis from the Planck spacecraft suggests that there is no observable non-trivial topology to the universe.

Updates on the EM Drive and Cannae Drive at Eagle Works - http://www.nextbigfuture.com/2015/04/eagleworks-nasa-updated-emdrive-models.html

A magnetic field is the space surrounding a magnet in which magnetic force is exerted. The motion of negatively charged electrons in the magnet determines not only the polarity, but also the strength of the magnet (Cold magnet).

Space is very cold.
If the motion of negatively charged electrons can can be directed in a certain direction then the entirety of the force being exerted can possibly propel an object forward.
 
Isaac Arthur (my favorite YouTube physicist) just dropped a 40 minute video dedicate to different spaceship propulsion technologies and concepts. He spends the last 10 to 12 minutes on the EM drive:

I think the whole video is well worth a watch, but the EM part starts at 28:35.
