5. Identify the following words using the given pictures below. HYDROGEN GEN

6. Identify the following words using the given pictures below. UNIVERSE NI

7. Identify the following words using the given pictures below. EXPANSION N

8. Cosmic Origin of Elements

9. Learning Objective: Determine the elements formed after the Big Bang explosion.

10. Big Bang Theory

11. Big Bang Theory The theory that describes the  universe  as originating in an infinitely tiny, infinitely dense point 14 billion years ago, from where it has been expanding ever since.

12. A concept that universe expanded from an infinitely small, infinitely dense, and infinitely hot point that is believed to have existed before the big bang. Bindu Singularity Rig Veda Primordial mixture

13. Why is the Big Bang Theory the most widely accepted theory for the origin of the universe? The events that happened in the big bang theory are the same as how God created everything. Science has already proven it without any reservations. Majority of scientists in the world conclude that it is the best idea so far. The theory has observable evidence such as the abundance of elements, expansion of space, and cosmic microwave background radiation.
