The useful idea
- The useful idea
In physics, gravity (from Latin gravitas 'weight'), also known as gravitation or a gravitational interaction, is a fundamental interaction, which may be described as the force that draws material objects
- How it works
The gravitational attraction between clouds of primordial hydrogen and clumps of dark matter in the early universe caused the hydrogen gas to coalesce, eventually condensing and fusing to form stars.
- Why it matters
At larger scales this resulted in galaxies and clusters, so gravity is a primary driver for the large-scale structures in the universe.
Why this matters
Look for Gravity the next time you notice this pattern in everyday life.
