Traditionally, we I believe that the Milky Way galaxy was a flat spiral galaxy. There are many beautiful images online and in books that have been artist renderings of what we believe our galaxy look like based on what we knew. Or at least what we believe me now.
One of the problems with trying to understand what our Galaxy looks like, is that we are inside it trying to look out. Meaning our perspective could easily be skewed based upon our position. Causing us to see what appears to be something flat. Similar to hell our ancestors once seen the Earth is flat instead of spheroid and shape. However like our ancestors we may actually be wrong. At least according to one new research paper our perspective may not exactly be accurate.
This study titled, An intuitive 3D map of the Galactic warp’s precession
traced by classical Cepheids, our Galaxy may not be a flat spiral galaxy after all. Instead they have found that out galicy may actually be warped and twisted. Similar to galaxies like, ESO 510-G13.
More research of course is needed to verify their findings. Personally I like the idea that our traditional ideas may actually be wrong. Finding out something new, especially when it challenges our traditional views. Forcing us to accept change. Besides it would be great to see the new artistic renderings of what the galaxies looks like.
This is one of the reasons why science doesn’t ever say something is proven. Because, if something is proven then then it can’t be wrong even to a small degree. And here, we could be wrong in such a way it reshapes the Galaxy, literally.
Anyway – Who knows, 400 years from now we could actually have people denying a shape of the Milky Way. Hell-bent on the idea that it is flat, like flat-earthers do when it comes to our little blue planet.
