Question

A.
All mass in the Universe was in the form of gases, and gases take up minimal space.
B.
Only single atoms existed in the Universe, and they were squeezed together by magnetic fields.
C.
Only protons and electrons existed in the Universe, and they were pulled together by gravity.
D.
All mass in the Universe was once energy, and energy does not take up space.

Answer 1

The best answer to explain how everything in the Universe could have originated from a single point is:

D. All mass in the Universe was once energy, and energy does not take up space.

This relates to the concept of the Big Bang, where the Universe started from a highly dense and hot state. According to Einstein’s theory of relativity, energy and mass are interconnected (E=mc²), which implies that at the very early stages, what we now consider mass could have been in the form of energy. As the Universe expanded and cooled, energy transformed into particles, leading to the formation of matter.
