Very Interesting Article - Are We Made Of Other Galaxy Stuff?

Hey Space Placers!

Here is a very interesting article about how galactic winds could be responsible for galaxy growth and the atomic matter in galaxies.

The article states that up to half of all the matter in our Milky Way Galaxy could have come from other smaller galaxies. Ultimately that would mean that half of the atoms that make each one of us up would have come from other galaxies!

We know that the natural elements, other than Hydrogen, are made in the nuclear fusion process that powers the stars and when more massive stars die. But the gas, dust and elements that go into making the protostar would contain a large proportion of matter from other galaxies if this research is correct.

We also know that galaxies grow by collisions with other galaxies which forms a new galaxy in the process. We see this happening throughout the Universe, including our own Milky Way Galaxy. In about 4 billion years the Milky Way and Andromeda galaxies will collide to ultimately form a new galaxy - Milkomeda.

Additional research will be conducted to try and prove the results of this supercomputing result.
