• Para la segunda pregunta, los elementos pesados se formaron cuando los átomos ligeros dentro de las estrellas se fundieron durante una supernova, convirtiéndose en átomos más pesados.
• Para la tercera pregunta, el Big Bang es la teoría del comienzo del universo a partir de un punto único.

Answer:

• 1. when some condensing gas revolving around the sun collapsed into masses too small to become stars.
• 2. when light atoms within stars fused during a Super Nova, becoming heavier atoms.
• 3. the theorized beginning of the universe from a single point.
