“See You in Another Life”: The Life, Death and Rebirth of our Galaxy

The Gases of our Milky Way tell a story…

They say history repeats itself, and its only natural that the complexities of space provide insight into this idiom.

Researchers in Japan have discovered that through a process called “cold flow accretion”, gases rich in “alpha” elements (oxygen, magnesium, silicon) flowed through our primordial galaxy in the beginning, which settled and began to form stars.

When stars reach the end of their lives they explode as supernovas, re-releasing these “alpha” elements back into space.

As these supernova shock-waves rippled, newer warmer temperatures slowed down the cold flow, allowing new supernovas to introduce iron into these gases, changing their chemistry into new stars.

Radiation excreted and cooled. A new cold flow started the process again. New stars plentiful in iron began to form. One of these stars is our own sun.

Our galaxy is a combination of old and new, layered and amalgamated.

This process occurred over billions of years. We struggle with the ideas of life and death and an afterlife, but if there’s any example of time being irrelevant in relation to existence, it’s this one.

Maybe we’re all just stars awaiting supernova, waiting to return our richness to the ether around us.
