## Would gravitons have mass?

Table of Contents

Gravitons do indeed have mass, and their motions generate kinetic energy. Thus, they have both energy and mass, and they obey the law of conservation of energy and matter. If gravitons did not have mass there would be no physics that we could understand.

**What is the mass of a graviton?**

This result suggests that, if a massless spin-2 particle is discovered, it must be the graviton….Graviton.

Composition | Elementary particle |
---|---|

Theorized | 1930s The name is attributed to Dmitrii Blokhintsev and F. M. Gal’perin in 1934 |

Mass | 0 < 6×10−32 eV/c2 |

Mean lifetime | Stable |

**Why does mass create gravitons?**

According to theory, the reason mass is proportional to gravity is because everything with mass emits tiny particles called gravitons. These gravitons are responsible for gravitational attraction. The more mass, the more gravitons.

### What type of particle is a graviton?

graviton, postulated quantum that is thought to be the carrier of the gravitational field. It is analogous to the well-established photon of the electromagnetic field. Gravitons, like photons, would be massless, electrically uncharged particles traveling at the speed of light.

**Does light particles have mass?**

Since photons (particles of light) have no mass, they must obey E = pc and therefore get all of their energy from their momentum.

**What is a graviton made of?**

According to Einstein, matter distorts the very fabric of space and time around it, creating the effect of an attractive force field. But quantum theory describes all forces in terms of so-called ‘exchange particles’, flitting from place to place. In the case of gravity, those particles are known as ‘gravitons’.

#### Does gravity have a particle?

In a quantum theory of gravity, the gravitational force must be carried by a suitable messenger particle, or gauge boson. No workable quantum theory of gravity has yet been developed, but general relativity determines some of the properties of the hypothesized “force” particle of gravity, the so-called graviton.

**Why does mass not affect gravity?**

Increasing force tends to increase acceleration while increasing mass tends to decrease acceleration. Thus, the greater force on more massive objects is offset by the inverse influence of greater mass. Subsequently, all objects free fall at the same rate of acceleration, regardless of their mass.

**How much mass is required for gravity?**

Given the amount of radioactive stuff left in the solar system today (it’s been draining away for the last 5 billion years) an object needs to have a mass between about 1 x 1023 kg and 3 x 1023 kg (between 0.02 and 0.05 Earths, or around 70 million “Deimoses”), give or take.

## Can gravitons travel faster than light?

Even if gravity crosses the event horizon, it can not be said to travel faster than light.

**Is there gravity without mass?**

The only way to get gravity is with mass. The more mass, the more gravity you get. Without mass, you can’t have gravity.
