Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Scientists theorize that the portion of the universe visible today expanded explosively from a hot, dense mass about 14 billion years ago. What is evidence for this “big bang”?
A
tides on Earth caused by the big bang’s gravitational forces
B
volcanoes on Venus, which erupt because of the force of the “big bang”
C
cosmic background radiation, which is energy left over from the big bang
D
the formation of black holes caused by the collapse of very hot dense massive stars
Explanation: 

Detailed explanation-1: -The Big Bang is the most widely-supported theory today regarding the origin of the universe. It states that about 13.8 billion years ago, the universe expanded from an extremely small, hot, and dense point called a singularity.

Detailed explanation-2: -The universe began, scientists believe, with every speck of its energy jammed into a very tiny point. This extremely dense point exploded with unimaginable force, creating matter and propelling it outward to make the billions of galaxies of our vast universe. Astrophysicists dubbed this titanic explosion the Big Bang.

Detailed explanation-3: -The Big Bang theory says that the universe came into being from a single, unimaginably hot and dense point (aka, a singularity) more than 13 billion years ago. It didn’t occur in an already existing space. Rather, it initiated the expansion-and cooling-of space itself.
