Every atom in your body is billions of years old. Hydrogen, the most common element in the universe and a major feature of your body, was produced in the big bang 13.7bn years ago.

How are atoms in my body billions of years old?
Most of the elements of our bodies were formed in stars over the course of billions of years and multiple star lifetimes. However, it’s also possible that some of our hydrogen (which makes up roughly 9.5% of our bodies) and lithium, which our body contains in very tiny trace amounts, originated from the Big Bang.

What’s the oldest atom in my body?
Are the atoms in my body as old as the universe? The hydrogen in your body is probably as old as the Big Bang, 13+ billion years. The rest of the elements in our bodies are no older than the star that went supernova in our galactic neighborhood 5+ billion years ago.

Are our atoms as old as the universe?
The atoms in your body were created at the start of our universe during the Big Bang. So if you look at it this way, then you’re about 13.7 billion years old.

How did the atoms in your body get there?
Every day, our bodies take in new atoms from the air we breathe, the food we eat, and the liquids we drink. These atoms are incorporated into our cells and fuel the chemical processes that keep us alive. But our cells are constantly being regenerated. The DNA in each cell copies itself over and over again.

Where were the atoms in man’s body billions of years ago?
For certain though, all the atoms that make up your body were forged billions of years ago in the fusion reactors at the core of now long-dead stars.

Is every atom in my body replaced?
But what they may not know is that the body does its own extreme makeover regularly. In fact, 98 percent of the atoms in the body are replaced yearly.

Are atoms as old as the universe?
“We contain matter as old as the universe” (absolutely. Pretty much all the hydrogen nuclei – and even a few sneaky deuteriums – in your fleshy vessel are 13.7 billion years old, the leftovers of primordial nucleosynthesis). But what you probably haven’t heard before is “We all began with molecular hydrogen”.

Are our bodies as old as the universe?
Most of your body is made of hydrogen and oxygen bonded as molecules of water. That means your body is made up of atoms that are 13.7 billion years old.” The atoms in your body were created at the start of our universe during the Big Bang. So if you look at it this way, then you’re about 13.7 billion years old.

How old are atoms on Earth?
So, most hydrogen atoms are 13.7 billion years old as they were formed in the Big Bang. If you have a large atom, it’s formed from the fusion of small atoms so it’s likely to be younger. But any sort of random atom you pick could be anything from 13.7 billion years old to made the other day in a fusion reaction.

Is the universe is made up of some of the same atoms as humans?
For decades, science popularizers have said humans are made of stardust, and now, a new survey of 150,000 stars shows just how true the old cliché is: Humans and their galaxy have about 97 percent of the same kind of atoms, and the elements of life appear to be more prevalent toward the galaxy’s center, the research …
