The Mycelial Network was just...honestly, #StarTrekDiscovery would have been so much better without it.

It is essentially a plot-hole generating machine.

Spoilers to folllow.

The Network is a multiverse spanning collection of spores that allows for instantaneous travel to any point in any universe.

Which is why 100 years after its discovery, Starfleet is still limited to a narrow slice of the galaxy about 500 lightyears around Earth.

And why Voyager had to spend 7 years traveling through the Delta Quadrant at high warp instead of just instantaneously jumping back.

Yes, yes, yes, they classified the Network's existence. Nobody knows about it.

Do I have to point out how incredibly implausible it is that in a galaxy teeming with warp-capable civilizations, humanity is the only species to discover this technology? I guess the Borg never assimilated anyone with knowledge of the network's existence, right?

If you use the Network as a power source, it doesn't just destroy your universe, it destroys the entire multiverse.

The evil Terran Empire from the Mirror Universe tried to do just that, but Discovery stopped.

But out of infinitely many universes, the Terran Empire was the only group that ever tried to use the Network as a power source?

Aren't there parallel universes with nearly infinite terran empires. I guess they were all stopped by parallel Discoveries?

Except that if the theory of the multi-verse is that all possibilities happen, then shouldn't there be a version of the Mirror Universe that is exactly like the one we know only its corresponding Discovery never visited. AAAH!

Despite what you might think after this thread, I actually like Star Trek Discovery a lot. But I really dislike the Mycelial Network as a plot device.

It has the same turn off your brain/don't think about it dynamic as the Kelvin films.
