Fusion Lighting the Stars

by Rob Rey

Stars are continuous nuclear explosions! Not simply fixed masses of hot gas, stars are a balance of two enormous forces: gravity and nuclear fusion. On its own, gravity would crush a star into the oblivion of a black hole or other super-dense entity. But nuclear fusion pushes back, releasing so much energy that the outer layers of the star are literally blown away, aloft from the core, and in equilibrium with gravity. From lightyears away, these cataclysmic explosions flutter as faint candles in our night sky.

Stars live a looong time, billions of years, but eventually the fuel of fusion runs out and gravity prevails. In the span of the universe, stars exist as temporary states of matter that will one day transition into other things. Much of their mass will be crushed. But in the process, many will fuse carbon, the other elements of life, and form planetary nebula. Later, these nebula will condense into new solar systems, and perhaps be part of some other temporary state of matter lucky enough to be able think about it.

Art to help make science a more meaningful part of our lives.

Cosmic Perspective is using the insights of modern science to see the big picture of the world and our place in it with a sense of belonging and connection. It’s understanding our scale within the universe - being humbled by a grand and awe-inspiring expanse of space and deep time. But it’s also seeing the very small with a sense of wonder for the staggering complexity of biology, chemistry, and quantum mechanics. Making an effort to comprehend the cosmos has a way of putting our lives, troubles, and pride in a helpful frame of reference, allowing us to refocus on what matters most. When we see the Earth as a lonely blue speck of oasis, it naturally sparks feelings of fellowship with all other earthlings. Through this panoramic lens, our terrestrial disputes and nationalist contentions are reduced to insignificance. Empathy and compassion become obvious ways to relate to one another.

In a time when our traditional sources of meaning are growing less resonant, Cosmic Perspective provides a new and inspiring scientific origin story of humanity, united by our shared atomic history as stardust. It provides a sense of kinship with all life on earth in our shared genetic evolution over four billion years of development. It provides a sense of belonging and responsibility as a crew member on this spaceship Earth, of which humanity now sits at the helm. It provides hope in our capacity to reason and understand the cosmos of which we are part, giving us new powers to cure disease and improve our lives. It provides us with purpose and necessitates cooperation to preserve and cherish our tiny planet, the only habitable place we know to exist.
