## Is there anything infinitely small?

In physical reality – no. **Anything infinitely small does not exist** although some objects act as if they are point-like.

## Are electrons infinite?

Thomson in 1901) and for far longer than physics has been compli- cated (but, some would say, simplified) by quantum mechanics. For if electrons are strictly point-like objects, their self-en- ergy, most simply taken as their potential energy in the electric field which they carry, **must be infinite**.

## Is electron small or large?

**An electron itself is small** (its size is not known, but we do know that it is smaller than a nucleus), but it occupies the space of the atom by constantly whirling around in a kind of orbit around the nucleus. 10^{–}^{15} m in radius. The proton and neutron have almost the same mass – the neutron’s is slightly larger.

## Can we go infinitely small?

Physics has a problem with small things. Or, to be more precise, with **infinitely small things**. We imagine that we can move any distance we like, no matter how small. … Since all of particle physics relies on “point-like” particles, reacting to forces in tiny spaces, one can anticipate trouble.

## Are electrons infinitely dense?

An electron has a mass of 9.10938291(40)×10−31kg. It also has a volume of 0m3. This would imply it **has infinite density**.

## Is orbit infinite energy?

Thus, if we accelerate a mass for some distance by using some force, we are doing work, and we must have had energy in order to do that work. In orbit, planets change direction, which is a change in velocity, which is an acceleration. … Thus, **infinite work will be done on the planets as they orbit**.

## What’s the smallest thing ever?

Protons 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.

## Is quantum space infinite?

Quantum sets have been proposed long ago by Finkelstein in the formulation of quantum relativity [23]. This straightforward numerical analysis is a strong indication that **quantum space-time could be infinite-dimensional** and that it may indeed be fractal at its very core.

## Is an electron the smallest particle?

The Ancient Greeks had a name for the smallest particle: the ‘atom’, meaning ‘not cuttable’. … But there’s one subatomic particle that’s far smaller still, and not even the most powerful particle accelerator has come close to pinning down its size: the electron.

## How small is a Planck particle?

Particle accelerators are described by the energies that they can produce, and the latest generation produces energies of ~10 TeV, or 10^{13} eV. The Planck energy is **1.2 x 10 ^{28} eV**. We are short by a factor of 10

^{15}.

## What is smaller than electrons?

And then those atoms are made up of protons, neutrons and electrons, which are even smaller. … And protons are made up of even smaller particles called **quarks**. Quarks, like electrons, are fundamental particles, which means they can’t be broken down into smaller parts.

## Is a quark the smallest particle?

Quarks are **among the smallest particles in the universe**, and they carry only fractional electric charges. Scientists have a good idea of how quarks make up hadrons, but the properties of individual quarks have been difficult to tease out because they can’t be observed outside of their respective hadrons.

## Can a wormhole exist?

In the early days of research on black holes, before they even had that name, physicists did not yet know if these bizarre objects existed in the real world. The original idea of a wormhole came from physicists Albert Einstein and Nathan Rosen. …

## How big is a quantum black hole?

Such a density would have been enough to create black holes a mere **10 ^{35} meter across** (a dimension known as the Planck length) with a mass of 10

^{8}kilogram (the Planck mass). This is the lightest possible black hole according to conventional descriptions of gravity.

## How small is a quark?

It is, as one might expect, very small indeed. The data tell us that the radius of the quark is **smaller than 43 billion-billionths of a centimetre** (0.43 x 10^{−}^{16} cm).

## Is time Travelling possible?

In Summary: Yes, **time travel is indeed a real thing**. But it’s not quite what you’ve probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second.

## What did Einstein say about wormholes?

Einstein and Rosen found that, theoretically, every black hole is paired with a white hole. **Because the two holes would exist in separate places in space, a tunnel — a wormhole — would bridge the two ends.**

## What creates a white hole?

White holes are created **when astrophysicists mathematically explore the environment around black holes, but pretend there’s no mass within the event horizon**. What happens when you have a black hole singularity with no mass? White holes are completely theoretical mathematical concepts.
