It turns out that the Milky Way (mmm Milky Way) is bigger than originally thought. Fifty percent bigger!
“The Harvard team discovered that the Milk Way is currently rotating at a speed of 600,000 miles per hour, which is 100,000 miles per hour faster than estimates from the past. This math equates to a 50% mass increase over what was initially reported” (TG Daily).
Don’t ask me how they do the math. I have no idea.
It also seems that this isn’t as awesome as one might expect. How could having a bigger galaxy not be good?
“A drawback to this finding is that there is a greater potential for collision with the Andromeda Galaxy, which has been known for some time to be ‘stuck with us’ rather than moving further and further away as other galaxies are. It appears also that the increase in mass may cause a collision sooner rather than later” (TG Daily).
[Side note] On behalf of the people of the Milky Way, I would like to extend “the finger” to the Andromeda Galaxy. Not cool Andromeda Galaxy… not cool at all.
I’m not going to lie, I don’t know exactly what a galaxy collision means for us, but I’m going to guess that it is akin to “crossing the streams.” It would be bad.
If you don’t know what “crossing the streams” means, I recommend you watch the original Ghostbusters movie. It’s a must watch before the end of world.
Be afraid we should collide with the Andromeda Galaxy in under 4 billion years.
Here is a video that shows what happens when galaxies collide.
