This is such a great video on putting into perspective how long it would really take to explore our Milky Way Galaxy.
Even then, it is still a bit off on the scale of our Milky Way Galaxy.
The 150,000 over-shoots the Thin Disk & conflates it with the Thick Disk.100,000 light years is the common assumed size of the Milky Way but...no...it's bigger than that. Pretty close to 150,000 at the extreme and not even accounting for all of the various satellite galaxies.
As to the number of actual stars in the Milky Way - the estimates have been increasing since many more red dwarf stars have been spotted. Brown dwarf stars are another matter altogether...
I don't have much faith in AI's calculations compared to human calculated numbers.According to AI;
With theoretical warp capability (assuming speeds ∼1,000 to 9,000 times the speed of light), exploring the
100,000–180,000
light-year wide Milky Way could take between 11 and 100 years.
Additionally;
Time Constraints: While a warp ship could cross the galaxy in a human lifetime, exploring (stopping at systems) would likely take thousands of years, notes this Quora post.
- Relativistic Effects: If approaching light speed, the crew would age slower than those at home due to special relativity, making long journeys feasible within a single lifetime, according to this Quora post.
My calculations came up with perhaps a more reasonable figure of;
50 Bazilion Years…

There's charting space, and then exploring space. I would argue the latter takes far longer. A brief scan of a planet or star system will tell a ship like Enterprise the basics, but a full survey by a dedicated science vessel will likely involve investigating every single thing possible and could be quite time-consuming & tedious to anyone other than scientists. I could see a science vessel spending weeks and even months studying a single planet and whatever life-forms it might have before moving on to the next one.
Agreed. We're not done fully exploring just the one planet yet, and it's been many millennia so far.This. And then Dr. Crater enters the chat, along with the various duck blind research outpost folks, the Calder II outpost/ruins folks, et cetera, et cetera.
To fully explore? Forever.
