Check out this mind-blowing, heart-bursting, video of the beauty of the Earth and our Universe as you’ve never seen it.
Every image in this video comes from picture frames taken by the International Space Station, courtesy of NASA. It shows the immensity of the universe, and the utter magic of connectedness in everything. It would be easy to look at this and feel that we are but a speck lost in space . After all, our sun is just one of 50 billion stars in the galaxy and there are billions of galaxies. Still, rather than feeling separation, the video brings an absurdly wonderful sense of celebration and a feeling of kinship: Because stars exist, we exist. The processes that created those billions of unimaginably distant galaxies also created us.
You and I are not merely separated from the galaxies by unimaginable immensities of space, we are connected to them by unimaginable immensities of time. We are literally made from stars. We are their descendants. The only difference between us and stars is time. The scientific fact is that the carbon, nitrogen and oxygen atoms in our bodies, as well as atoms of all other heavy elements, were created in previous generations of stars over 4.5 billion years ago. Because humans and every other animal — as well as most of the matter on Earth — contain these elements, we are literally made of star stuff.
From Physics Central:
Every element in the periodic table (aside from hydrogen) is essentially stardust…but how much of our body is made up of this stardust? Since stardust atoms are the heavier elements, the percentage of star mass in our body is much more impressive. Most of the hydrogen in our body floats around in the form of water. The human body is about 60% water and hydrogen only accounts for 11% of that water mass. Even though water consists of two hydrogen atoms for every oxygen, hydrogen has much less mass. So, we can conclude that 93% of the mass in our body is stardust.
You know this, right? It’s been popularized in the media, but in case you’ve missed it, here are our three favorite references:
1) At Woodstock, Joni Mitchell famously sang about this in a song aptly titled “We are stardust.”
”Billion year old carbon.
We are golden..
Caught in the devil’s bargain
And we’ve got to get ourselves back to the garden.”
2) In 2002, music artist Moby released “We Are All Made of Stars,” explaining during a press interview that his lyrics were inspired by quantum physics. “On a basic quantum level, all the matter in the universe is essentially made up of stardust,” he said.
3) In the early 1980s, astronomer Carl Sagan hosted and narrated a 13-part television series called “Cosmos” that aired on PBS. On the show Sagan, thoroughly explained many science-related topics, including Earth’s history, evolution, the origin of life and the solar system.
“We are a way for the universe to know itself. Some part of our being knows this is where we came from. We long to return. And we can, because the cosmos is also within us. We’re made of star stuff,” Sagan famously stated in one episode.
Just think, long ago someone may have wished upon a star that you are made of.
