On stardate 50252.3 - the USS Voyager  reached the extensive territory of the mysterious Swarm. It would take the crew of Voyager several months to fly around this region of space. Therefore the crew decided to cross the territory of the Swarm at a narrow place. Unfortunately, no scale is given that would allow an estimation of the dimensions of the territory. But Chakotay did make two remarks concerning the time necessary to travel through the region of space:

1. Travelling through the territory will last 4 days at very high warp speed.

2. Sustaining warp 9.75 for 12 hours, Voyager has travelled a third of the distance.

Based on this premise, Voyager can travel 27.4 ly in 4 days. If this is a third of the distance, the whole route is approximately 82 ly long. The comparison of this route  with the whole shown territory of the Swarm leads to a dimension of the shown region of nearly 570 ly - and borders aren't visible. After all these calculations, we certainly know that the territory of the Swarm is really quite large, but it seems to be considerably smaller than for instance Borg space, and it is restricted to a length of less than 1000 ly, because the crew never meet the Swarm again.


 
 

The Nekrit Expanse is described as an extensive, unsurveyed, unstable region of space which is full of interstellar dust clouds and plasma storms, but contains only few planets. The expanse has a width of several thousand light years, but seems to be not very deep since Voyager can cross the region in relatively short time. Consequently, Voyager was definitely inside the Nekrit Expanse between stardate 50443 and 50654 - what results in a total time of 211 stardate units or 77 days.Using the maximum cruising speed of Voyager - warp 8, we get a depth of 216.017 ly for the Nekrit Expanse, a figure, that is  plausible in view of the large width and the ignorance of the people in the regions explored by the USS Voyager about the space behind the expanse.


 
 
 


The Mutara Class nebula (see images below)

In late 2374, on stardate 51929.3, the USS Voyager reaches a vast Mutara class nebula, whose borders are beyond the sensor range. Therefore Voyager can't fly around and also cannot simply travel through due to dangerous radioactivity within the nebula. In the astrometric lab, Captain Janeway and Seven consider the remaining possibilities by scanning the spatial size and shape of the nebula with the more advanced astrometric sensors. The expansion of the nebula is said to be at least 110 ly, perhaps even more. It would take Voyager a month to travel through and more than one year to fly around. Due to the sub-nucleonic radiation, the crew has to stay unconsciously in stasis chambers during the travel through the nebula and assign command to Seven.

Twisted Space

Encountered by Voyager in 2371, the region of twisted space initially caused various minor systems failures on board the ship, most notably in the communications system. The ships layout had changed radically. Worse, the layout was continuing to change on a second by second basis, without the crew being at all aware of the changes. Captain Janeway and Ensign Kim encountered some form of field which appeared to be distorting space itself. Janeways arm became enveloped in the field and although Kim was able to free her, the after-effects resulted in severe delirium.

The distortion enveloped the entire ship then vanished of its own accord, leaving Voyager and her crew completely undamaged. After the distortion had ended, Voyagers crew discovered that 20 million gigaquads of new information had been downloaded into the ships computer systems. Even now it is unclear exactly what the nature of the distortion effect was. It may have been caused by a vessel occupying multidimensional space, or indeed may have been a vessel of some form in itself. It is even possible that the field was a life form in its own right.

Vardwuar Corridors

The underspace corridor network surrounding the Vaadwuar homeworld is a natural phenomenon which allows ships to travel at far greater than normal speeds. The corridors were formerly controlled by the Vaadwuar themselves, who spent centuries mapping them and used them to allow trade with many other species and for military expansion of their territory. Approximately 1400 years ago the Vaadwuar were defeated by an alliance composed of their various victim species including the Turei. The alliance subsequently claimed control of the corridor network. In 2376 Voyager was caught up in the network. Voyager found that the corridor had allowed them to cross two hundred light years of space in under five minutes, an average speed of over twenty million times the speed of light.

Neutronic Wavefront

A neutronic wavefront is a phenomenon which is produced when two neutron stars collide. The collision forms a ring structure which expands outwards at a significant fraction of the speed of light. In 2376 USS Voyager encountered a class nine neutronic wavefront which was expanding at 200,000 kilometres per second, approximately 66% of light speed. The phenomena extended for 3.6 light years, indicating that the collision had taken place several years previously. The ship experienced energies of well over 90 million terajoules of neutron radiation.
