What are Some Unsolved Problems in Cosmology?
Cosmology, the study of the universe, is plagued by numerous unsolved problems. Historically, these unsolved problems prompted new developments in physics which went on to revolutionize the field, but in the last half-century, cosmologists have been discovering new problems and providing fewer corresponding solutions. Finding the solutions to these problems may require radical new thinking, and more tolerance towards hiring PhDs inclined to pursue their own ideas rather than just following those of senior scientists. One of the most conspicuous problems in cosmology is the cosmological constant, which governs the expansion of the universe, also known as dark energy. A substantial portion, about 60%, of the mass-energy in the universe is in a form of mysterious energy that is pushing the cosmos apart at an accelerating rate. What is this energy, and where does it come from? Cosmologists have no real idea. Although given a similar name, there is another problem in cosmology, the so-calle
