How Sun Destroyed 99.8% Of All Matter

Описание: This video examines the formation of the Sun and the earliest stages of our solar system, when a collapsing cloud of gas and dust gave rise to a single dominant star. Using evidence from astrophysics and planetary science, it explains how gravity caused most of the material in the solar nebula to fall inward, feeding the growing Sun while heating and dispersing the surrounding disk.
Roughly 99.8 percent of the original mass ended up in the Sun, a result confirmed by measurements of solar and planetary composition. The remaining 0.2 percent persisted as dust grains and gas trapped in orbit, gradually colliding and sticking together through accretion. Over millions of years, these small remnants formed planetesimals, protoplanets, and eventually the rocky and gaseous worlds of the modern solar system. Meteorites preserved from this era provide direct chemical evidence of these early processes and help scientists reconstruct the conditions that shaped Earth.
The video places Earth’s existence in a stark context. Every continent, ocean, and living organism is built from material that avoided being consumed during the Sun’s violent growth. The solar system is not the product of abundance, but of survival within an extreme gravitational environment.
