The magnetic couplers have been repaired. No more odd places, as long as the plating holds.
...the Burn caused tens of thousands of ships, hundreds of stations and starbases to explode across the galaxy. Millions of dead floating lifeless in the vaccum of space and twisted hulls of starships for the last 125 years.
That's not counting the thousands of worlds with cities on them....billions of people dependent upon dilithium for everyday operations.
It's doubtfull that Discovery will be a cheerful ship after season four. Especially after the first city they come acorss...only their bones and the wild that gnawled on them will be found.
Then there are the mutations to DNA of people effected by the Burn.
We can't forget about those who were transported into one of the three dimensions dilithium exists in either.
What the Discovery jumped into in the 32nd century is more than just some lost starships. Discovery jumped into a galaxy wide Ground Zero, a graveyard of the past.
