Do You Know That The Matter We Are Made Of Came From Another Galaxy

Humans, a new study has found, are intergalactic travellers!

According to a new research, humans are formed from matter that travelled, floated rather, from another galaxy billions of miles away. Also, most of which exists around us and across the Milky Way is composed of ¡°extragalactic stuff¡±.

Computer models were used to find out how things that surround us travelled all the way to our galaxy, and found that supernova explosion, or exploded stars, throw out ginormous amounts of matter, which then travel through the universe by the force of galactic winds.

That means that the same matter that we're made from probably began its life in a long distant time and far, far away, before being carried through the universe.

Daniel Angl¨¦s-Alc¨¢zar, a postdoctoral fellow in Northwestern's astrophysics center, said, ¡°Given how much of the matter out of which we formed may have come from other galaxies, we could consider ourselves space travelers or extragalactic immigrants. It is likely that much of the Milky Way's matter was in other galaxies before it was kicked out by a powerful wind, travelled across intergalactic space and eventually found its new home in the Milky Way.¡±

The phenomenon of intergalactic transfer ¨C that is, the movement of matter between galaxies ¨C is a recently discovered one and could give us a more acute understanding of how galaxies are formed.

Faucher-Gigu¨¨re, who co-authored the study, said, ¡°This study transforms our understanding of how galaxies formed from the Big Bang. What this new model implies is that up to one-half of the atoms around us ¨C including in the solar system, on Earth and in each one of us ¨C comes not from our own galaxy but from other galaxies, up to one million light years away."

The universe is an unimaginably large entity so matter took billions of years to reach our galaxy despite travelling at hundreds of kilometres per second.

Faucher-Gigu¨¨re, a member of CIERA, said, ¡°Our origins are much less local than we previously thought. This study gives us a sense of how things around us are connected to distant objects in the sky.¡±
