A Universe from Nothing


Based on: A Universe from Nothing

By Lawrence Krause


Stardust

Even though it may be a bruise to the ego to think that we are not the center of our universe, it’s even more of a miracle think of how enormous the universe is and how blessed we are to be a part of it. Galaxies that are ever more distant are moving away from us with faster velocities. From our perspective, it appears that we are the center because everything is moving away from us. When we look at another galaxy through the Hubble telescope, we are really seeing that galaxy 50 million years ago, because that’s how long it took for the light to reach us.
Every atom in our bodies is the result of an exploding star. We are literally made of stardust. Matter is compressed in a dense plasma to about 10 billion degrees Kelvin, causing nuclear reaction between protons and neutrons. This is what probably caused the big bang which eventually gave us life.


Runaway Universe
There is so much in this universe that is unseen. This is what is known as “dark matter.” 70 percent of the total energy in the universe is not even made of matter, but empty space itself. In other words, nothing equals 70 percent of the universe.
Quantum fluctuations, which we would perceive as nothing collapsed stars, created galaxies, and essentially gave us life.  Without these quantum fluctuations, the existence of dark matter, and the existence of gravity, galaxies would have never been born, then stars would never form, planets would never exist, and life would never be born.
It is also possible that multiverses exist. This would suggest that our universe is not unique. Our universe is so vast that it seems entirely possible that others could exist as well. This is where string theory comes from. The idea that other dimensions exist right in front of us just at different vibrations create different notes on the strings of a violin. So, the elements we see every day have vibrations that our eyes cannot see.

Nothing is Something
It is not crazy to say that something comes from nothing. For example, an electron-positron pair naturally pops out of empty space from nowhere near an atom’s nucleus. In other words, a chemical element pops in and out of existence. Is it coming from another universe, another dimension? Who knows, but this does show that there is much more in this universe that what our five senses can perceive.
If matter and antimatter came into contact, the result would cause complete annihilation. It is possible that matter and antimatter created the explosion that gave life to galaxies and stars. So it may be that nothing colliding with something may have given us life.

 “Space is big. Really big. You just won’t believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that’s just peanuts to space.”

  1. It's just amazing to think how vast the universe is. I'm so thankful to be a small part of it.
