Neil deGrasse Tyson | The Origin of the Universe

The origin of the universe is certainly among the most intriguing topics in all of science. Neil deGrasse Tyson explains how the universe came to be. He explains the big bang theory and the subsequent evolution of the universe.

Neil deGrasse Tyson not only explains the origin of the Universe, he also gives an inspiring speech about the origin of life on Earth and our place in the cosmos. 

The universe has inspired scientific discoveries in a broad array of disciplines including astronomy, physics, chemistry, mathematics, and biology. The Big Bang itself forms the basis of the current Standard Model of cosmology, which describes the evolution of the universe from the earliest known states through the appearance of structural fragments.

The latest data shows that the expansion of the universe is accelerating. This means that the galaxies are moving further apart from each other which indicates that space is stretching. It has been suggested to explain this by the gravitational potential of dark energy. This theory suggests that dark energy has a positive pressure which pushes the universe apart.

Dark energy is the most accepted explanation for the observations of an accelerating universe. And it remains an active field of research in cosmology.

Neil deGrasse Tyson also briefly mentions the Multiverse hypothesis and how it fits with the big bang model.

Information from modern experiments, such as the Planck satellite and WMAP short for Wilkinson Microwave Anisotropy Probe, and from astronomical observations in the 21st century, has allowed cosmologists to increase the precision of their predictions about the universe's age early in the universe's history. 

It is fascinating to think how much of the nature of the universe science has revealed to us. But we're still only scratching the surface of a cosmic iceberg. Most of the universe, and the multiverse, if it exists, still remains in the realm of the unknown. But scientists are determined in the quest to expand the frontier of knowledge and push the boundaries of ignorance, and shed a light to an ever growing and expanding universe.
