# Why charge without mass is not possible?

## Why charge without mass is not possible?

The statement that “a charge can exist without mass” is false. This is because none of the fundamental particles that form the Standard Model have charge without mass. The Standard Model describes all energy and matter that makes up the universe, except gravitation. And gravitation does not have charge, it has mass.

## Does dark matter have mass?

Dark matter is invisible, and scientists have long tried in vain to directly detect the mysterious particles. But since dark matter has mass, its presence is inferred based on the gravitational pull it exerts on regular matter.

## Does light have infinite mass?

Simply put, as an object approaches the speed of light, its mass becomes infinite and it is unable to go any faster than light travels.

## Is mass of photon infinite?

According to Einstein, a particle moving at the speed of light reaches infinite mass.

## How did Einstein come up with E mc2?

So he took this assumption–that the speed of light was a constant–and he returned to the mathematical and electromagnetic equations that were worked out years before. He then plugged in the letter “C” (a constant) to represent the fixed speed of light (whatever it might be) and low and behold… Out Popped E=MC2 !!

## What are the units of E mc2?

E = mc2—In SI units, the energy E is measured in Joules, the mass m is measured in kilograms, and the speed of light is measured in meters per second.

## What does C stand for in the formula?

the speed of light in vacuum

## What is the full equation of E mc2?

It just describes objects that have mass and that aren’t moving. The full equation is E squared equals mc squared squared plus p times c squared, where p represents the momentum of the object in question.

## How did Einstein calculate the speed of light?

It can be derived from Maxwell’s equations that the speed at which electromagnetic waves travel is: c=(ϵ0μ0)−1/2. Since light is an electromagnetic wave, that means that the speed of light is equal to the speed of the electromagnetic waves.
