The Universe and Light
In this chapter, we discuss how the universe arrived at its present appearance. The development of the universe and the reason why we are here today are described and figured out from the oldest light emitted 14 billion years ago.
The oldest light in the universe
Where did the oldest light in the universe come from? To answer this question is to reveal some of the universe’s most remarkable secrets.
“Invisible mass”—Dark matter
As much as 85 percent of the matter in the universe is said to be “dark matter.” How can we detect such matter when it does not reflect or emit light?
The dark energy that permeates the universe
Astrophysics has shown that dark energy exists. How does this dark energy, which permeates space, affect the universe?
Holes in space that swallow light
A black hole is an amazing pitch-black celestial object that radiates unimaginable levels of energy while at the same time swallowing up everything―even light itself.
The Sun—the Source of Life
Intricate granular patterns that come and go on the surface of the Sun. These could potentially lead to the answer to a long-standing mystery surrounding the Sun.
