Definition

A theoretical particle that is thought to be a fermion connected to the graviton in the context of supersymmetry and supergravity theories.

Example

Scientists are researching the properties of the gravitino to understand its role in the universe.

Conversation

Have you ever heard of a gravitino?

No, I haven't. What is it?

It's a hypothetical particle related to gravity in supersymmetry theory.

That sounds fascinating! I love learning about new particles.

Root Explanation

Gravitino is derived from "gravitas" (meaning weight or heaviness) and the suffix "-ino" (a diminutive suffix in Italian and Spanish, often indicating something small or lesser). The term "gravitino" refers to a hypothetical elementary particle that is a superpartner of the graviton, suggesting a small or lesser version of gravity-related phenomena.

Memory Tip

Think of 'gravity' as something heavy ('gravitas') and the '-ino' suffix suggesting something small or lesser. This helps you remember that a 'gravitino' is a small particle related to gravity.
