Satisfy Your Curiosity To Learn Complex Astrophysics Concepts Non-mathematically.

Satisfy your curiosity to learn complex astrophysics concepts non-mathematically.

If you are curious to enjoy complex astrophysics concepts and want to skip math in between and rather enjoy physical illustrations then you are at the right place. Don't let complex differential calculus, tensors, coordinate transformations, etc hinder your curiosity to know our universe (at least at some scale!). The book will fulfill your non-physicist level of curiosity to learn astrophysics concepts like black holes, wormholes, gravitational lensing, spacetime cutoffs, and many more

This book combines established astrophysics results and the author's lens to look at this universe being illustrated by pure imagination. The difficulty level of this book is medium and it strongly focuses on making concepts imaginative and understandable enough. And surely it would astound you as imagining astrophysics is another level of feeling.   Visit the link in the bio to get your copies!

We are made of Star Dust

Though the overwhelming majority of humanity has never grazed the cosmic void, our atoms derive from deep space.

Almost every atom within each of us was once actually part of a nebula - The exact same atoms that build our bodies, were created by stars.

Giant stars, far larger than our Sun, veer towards a dramatic death at the final stages of their spectacular existence - The remainder of a star's energy then irradiates gas and dust that collect all around it, generating new elements that will enrich the atmosphere from which future stars and planets can eventually form.

So over the course of billions of years, these atoms are "recycled" into an uncountable number of different things, in all possible configurations, from simple table salt (NaCl) to our own, very complex, helical DNA that make us uniquely...Us.

But it's always the very same atoms produced in these colossal stellar deaths: matter that dying stars shed from their external layers during the last phase of their life.

And what we're witnessing is death and rebirth on the cosmic scale!

The intense radiation from the star's final explosion then contributes, through collisions of all those atoms in the outer layers, to form heavier atoms (almost everything from Iron (Fe) onwards on the periodic table).

Without supernovae, none of what we have around us would exist!

What then remains in the centre depends on the mass of the star - some supernova events leave behind a super-dense neutron star, while other more massive stars leave behind black holes.

This is the dust (all atoms except hydrogen and helium) inside the giant star-forming region known as the Pillars of Creation, about 6,500 light-years away (source: NASA/ESA/CSA/STScl)

They are, in turn, part of a much larger region called the Eagle Nebula, a young open cluster of stars in the constellation Serpens, part of a diffuse emission nebula, or H II region.

This image here was taken by the camera of the James Webb Space Telescope, at infrared wavelengths.

Within its depths, are a myriad of protostars and early stars in formation.

Something went wrong, so I had to reupload this.

Anyway...
