Question: Can Things Pop Into Existence?

Do things exist when not observed?

Short answer: Yes, it exists as long as it interacts with something.

Long answer: Having a sentient observer isn’t needed for something to exist..

What does space smell like?

Astronaut Thomas Jones said it “carries a distinct odor of ozone, a faint acrid smell…a little like gunpowder, sulfurous.” Tony Antonelli, another space-walker, said space “definitely has a smell that’s different than anything else.” A gentleman named Don Pettit was a bit more verbose on the topic: “Each time, when I …

Do particles exist?

That is, there is no evidence that photons, electrons, protons and so on exist as particles, separate from the wave function—with “particle” being defined here as a carrier of mass, energy, momentum, spin and charge localized at or near a single point.

Can anything exist in a vacuum?

Quantum mechanics tells us that there is no such thing as empty space. Even the most perfect vacuum is actually filled by a roiling cloud of particles and antiparticles, which flare into existence and almost instantaneously fade back into nothingness.

What is inside a quark?

A quark is a tiny particle which makes up protons and neutrons. Atoms are made of protons, neutrons and electrons. It was once thought that all three of those were fundamental particles, which cannot be broken up into anything smaller. … Neutrons and protons are made up of quarks, which are held together by gluons.

Can virtual particles become real?

Virtual particles are indeed real particles. … Quantum mechanics allows, and indeed requires, temporary violations of conservation of energy, so one particle can become a pair of heavier particles (the so-called virtual particles), which quickly rejoin into the original particle as if they had never been there.

Why do particles pop in and out of existence?

At the quantum level, matter and antimatter particles are constantly popping into existence and popping back out, with an electron-positron pair here and a top quark-antiquark pair there. … Between the plates, only waves (particles) with wavelengths smaller than the separation between the plates can exist.

Can matter be created?

Water is composed of two hydrogen atoms bonded to an oxygen atom. Photograph by OJO Images Ltd. From port-a-potties to supernovas, matter makes up everything visible in the known universe. Because matter is never created or destroyed, it cycles through our world.

Is the quantum realm real?

The quantum realm (or quantum parameter) in physics is the scale at which quantum mechanical effects become important when studied as an isolated system., respectively.

Does the universe repeat?

Eternal return (also known as eternal recurrence) is a concept that the universe and all existence and energy has been recurring, and will continue to recur, in a self-similar form an infinite number of times across infinite time or space.

What is the smallest particle?

An atom is the smallest particle of an element, having the same chemical properties as the bulk element. The first accurate theory explaining the nature of matter was Dalton’s Atomic Theory: 1. All matter is composed of atoms, and atoms are indivisible and indestructible.

Do electrons pop in and out of existence?

3 Answers. No, electrons do not pop in and out of existence. They do, however, switch between localized and delocalized states: When the atom is undisturbed, the electron will be in the energy eigenstates of the system, the so-called atomic orbitals.

Do photons pop into existence?

These virtual particles often appear in pairs that near-instantaneously cancel themselves out. Still, before they vanish, they can have very real effects on their surroundings. For instance, photons—packets of light—can pop in and out of a vacuum.

Who created God?

Defenders of religion have countered that the question is improper: We ask, “If all things have a creator, then who created God?” Actually, only created things have a creator, so it’s improper to lump God with his creation. God has revealed himself to us in the Bible as having always existed.

Is empty space really empty?

Outer space is not completely empty—it is a hard vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium, as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays. … Outer space does not begin at a definite altitude above the Earth’s surface.

Do quantum fluctuations exist?

Physicists observe weird quantum fluctuations of empty space—maybe. Empty space is anything but, according to quantum mechanics: Instead, it roils with quantum particles flitting in and out of existence. Now, a team of physicists claims it has measured those fluctuations directly, without disturbing or amplifying them.

What keeps space empty?

Vacuum energy (also called vacuum fluctuations or zero-point energy) is a sea of particles and antiparticles flashing briefly into and out of existence. Vacuum energy has a very real effect because it weakens, or screens, electric fields.

Why is space black?

Around Earth and the inner solar system, for example, space is filled with dust particles that get lit up by the sun, creating a diffuse glow over the entire sky. But that dust isn’t a problem out where New Horizons is. Plus, out there, the sunlight is much weaker.

What is the smallest thing in the world?

quarksProtons and neutrons can be further broken down: they’re both made up of things called “quarks.” As far as we can tell, quarks can’t be broken down into smaller components, making them the smallest things we know of.

Can something be created from nothing?

“We usually say that nothing can be created out of nothing because we think it would violate the law of conservation of energy,” a hallowed principle in physics holding that energy can neither be created nor destroyed, Vilenkin explains.

Does past exist?

The past and future do not exist and are only concepts used to describe the real, isolated, and changing present. This conventional model presents a number of difficult philosophical problems, and seems difficult to reconcile with currently accepted scientific theories such as the theory of relativity.

Does Purepower exist?

So the full answer to the question of whether pure energy exists is: For all of the particles that exist, massive and massless, energy is only one property of them, and cannot exist independently.

What is quantum vacuum energy?

Vacuum energy is an underlying background energy that exists in space throughout the entire Universe. … Still, the exact effect of such fleeting bits of energy is difficult to quantify. The vacuum energy is a special case of zero-point energy that relates to the quantum vacuum.

Can subatomic particles exist by themselves?

But these basic atomic components are by no means the only known subatomic particles. Protons and neutrons, for instance, are themselves made up of elementary particles called quarks, and the electron is only one member of a class of elementary particles that also includes the muon and the neutrino.

What is inside a gluon?

In layman’s terms, they “glue” quarks together, forming hadrons such as protons and neutrons. In technical terms, gluons are vector gauge bosons that mediate strong interactions of quarks in quantum chromodynamics (QCD). Gluons themselves carry the color charge of the strong interaction.

How many dimensions are there?

The world as we know it has three dimensions of space—length, width and depth—and one dimension of time. But there’s the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.

What does the universe exist within?

The universe (Latin: universus) is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy.
