# Quick Answer: Can Anything Be Smaller Than The Planck Length?

## How long is a jiffy?

Harrison, the time it takes for light to travel one fermi, which is approximately the size of a nucleon.

One fermi is 10−15 m, so a jiffy is about 3 × 10−24 seconds.

It has also more informally been defined as “one light-foot”, which is equal to approximately one nanosecond..

## What is a Zeptosecond?

A zeptosecond is a trillionth of a billionth of a second (10^-21 seconds).

## What is the fastest thing in the universe?

And, while light is still by far the fastest thing in the universe, moving at a staggering speed of 299791.82 km/h, the following list contains some of the other closest things to reach that title of “World’s Fastest.”

## How long is a Planck second?

tP = (hG/2πc5)1/2 . The Planck time is 5.4 x 10-44 seconds.

## Can you split a quark?

Quarks,and leptons are thought to be elementary particles, that is they have no substructure. So you cannot split them. In future things might work out differently.

## How big is a quark?

10-18 meterThe smallest particles that have been found so far are quarks (protons, neutrons are made of quarks). A quark is no bigger than 10-18 meter.

## How big is the universe in Planck lengths?

The radius of the observable universe is approximately 46.5 billion light-years or 7.04×1061 Planck Lengths. This gives a volume of the observable universe of 4.65×10185 Cubic Planck Lengths.

## Is a Planck smaller than a quark?

The answers about the quark not having a particular size are correct. If instead you want to compare the mass of a quark to the planck mass (mp), you can. As you can see, the planck mass is much larger than the top quark mass.

## What is the biggest thing ever?

The biggest supercluster known in the universe is the Hercules-Corona Borealis Great Wall. It was first reported in 2013 and has been studied several times. It’s so big that light takes about 10 billion years to move across the structure. For perspective, the universe is only 13.8 billion years old.

## How small is a Planck particle?

Compared to a proton, for example, the Planck particle would be extremely small (its radius being equal to the Planck length, which is about 10−20 times the proton’s radius) and massive (the Planck mass being 1019 times the proton’s mass).

## What is smaller than a Zeptosecond?

A yoctosecond (ys) is a septillionth of a second or 10–24 s*. Yocto comes from the Latin/Greek word octo/οκτώ, meaning “eight”, because it is equal to 1000−8. Yocto is the smallest official SI prefix. A yoctosecond is the shortest lifetime measured, so far.

## Why is Planck length smallest possible?

So why is the Planck length thought to be the smallest possible length? The simple summary of Mead’s answer is that it is impossible, using the known laws of quantum mechanics and the known behavior of gravity, to determine a position to a precision smaller than the Planck length.

## What is the smallest thing in the universe?

An atom is the smallest unit of any element in the periodic table. … Experiments found that each atom has a tiny, dense nucleus, surrounded by a cloud of even tinier electrons. The electron is, as far as we know, one of the fundamental, indivisible building blocks of the universe.

## What is the biggest thing on earth?

The blue whale is the largest animal living on Earth today, and it is also the largest animal in Earth’s history. It reaches 33 meters in length and 150 tons in weight.

## Is anything faster than light?

For one thing, while nothing has ever been observed travelling faster than light, that does not mean it is not theoretically possible to break this speed limit in very special circumstances. … There are galaxies in the Universe moving away from one another at a velocity greater than the speed of light.

## What is inside a quark?

A quark is a tiny particle which makes up protons and neutrons. … After the invention of the particle accelerator, it was discovered that electrons are fundamental particles, but neutrons and protons are not. Neutrons and protons are made up of quarks, which are held together by gluons. There are six types of quarks.

## Is there a smallest unit of space?

The smallest possible size for anything in the universe is the Planck Length, which is 1.6 x10-35 m across.

## What is the smallest possible length?

In physics, the Planck length, denoted ℓ P, is a unit of length that is the distance light in a perfect vacuum travels in one unit of Planck time. It is also the reduced Compton wavelength of a particle with Planck mass. It is equal to 1.616255(18)×10−35 m.
