‘Nothingness’ Doesn’t Exist—Yet It’s the Reason You’re Alive and Conscious, Physicists Say
Susan Lahey · 2026-05-27 · via Latest Content - Popular Mechanics

Does what we conceive of as “nothing” even exist? According to quantum field theory—which is thought to be the most successful theory in all of physics for its ability to predict results of all kinds of experiments with extreme precision—there is no such thing as a true void in our universe. Even the biggest “nothing” of all, the void of space, is something: a vacuum. And within a vacuum, much more is happening than meets the eye.

Without matter or radiation, space is a vacuum with the potential to be anything. In fact, if we recast “nothingness” as a vacuum filled with zero-point energy—the baseline energy that fills all of space, according to quantum mechanics—you could say nothing is the reason why you and I exist in the first place. Some scientists even believe this nothingness is a substrate your brain attaches to in order to “receive” consciousness.

Quantum field theory says that we don’t live in a universe where matter floats around in empty space. Instead, we live in a universe of energy fields that spread throughout the universe and interact with one another, creating everything we see in the process; in fact, we are part of these fields. In describing them, some physicists refer to these fields as being fluid-like, like water in a swimming pool. Others have compared them to a field of heat distributed throughout a room with different levels of energy at different points.

The fields are constantly moving due to quantum fluctuations, which are momentary changes in energy, like ripples of energy in a wave, when something excites the particles in the field. An electromagnet, for example, might cause a change of energy in an electromagnetic field. The fields’ lowest energy state, the vacuum state, still teems with movement, because pairs of positive and negative particles continually borrow energy from the vacuum, pop into existence, and pop out of existence again, returning energy to the vacuum. These are known as “virtual particles.”

When the field is excited or reaches a higher energy point, it has ripples or waves that create elementary particles that are not canceled out. It is these particles that remain, interacting with one another, that creates the world we know.

The kind of particle the field creates depends on the kind of field it is. There are 12 fields of matter that produce electrons, up quarks, and down quarks—the building blocks of all atoms—and neutrinos. There are also three fields of force: electromagnetism with its particles, the photons; the strong nuclear force with its gluons; and the weak nuclear force with its W and Z bosons. As Cambridge theoretical physicist David Tong says, if it wasn’t for fields of force, the matter particles “would just wander around the universe like lost souls, never interacting, never doing anything interesting.”

Then there’s the Higgs field, which Tong compares to molasses, spread throughout the universe, giving other particles mass so that they don’t just zip around at the speed of light; though he admits that’s a faulty metaphor because it implies friction. In reality, different particles just interact differently with the Higgs field.

All the fields exist everywhere, but they all interact differently, with some particles completely ignoring each other, and some particles impacting each other and creating reactions.

Working together, these fields represent all that we know and can see, as well as a lot that we don’t know and can’t see. But, weirdly, the creation of particles that make something is the exception. An atom, for example, happens when there is enough energy in the quark fields to create quarks that don’t get canceled out by anti-matter quarks (though no one is sure why). Gluons, the particles of the strong force, connect with two up quarks and one down quark to create a proton. The gluons then connect protons with neutrons to form a nucleus.

Physicists believe that all of the visible universe is the leftovers, the one particle per billion that managed to survive virtual particles’ creation/destruction process.

But just because the universe is full of virtual particles, that doesn’t fully negate the idea of nothing. First of all, there’s the nothing before the Big Bang; we don’t know what that was. Also, we don’t understand the nature of this nothing—the vast fields of quantum energy—that seem like something that leaves a combination of ingredients, matter and force, to create a world. Physicists don’t know why, after the Big Bang, any elemental particles survived. In his book, A Universe from Nothing, theoretical physicist and cosmologist Lawrence Krauss implied that the answer was in the evidence. The unstable nature of nothing gives rise to elementary particles. Period. End of debate.

“The question why is there something rather than nothing is really a scientific question, not a religious or philosophical question,” Krauss said in an interview on NPR.

There is no provable answer right now: none, zip, nothing. Fortunately for philosophers and physicists, that’s where some of the best answers are found.
