Understanding the very early universe
24:07 - 38:29 (14:21)
The hope is to have a theory that applies to the extreme early stages of the universe but which also accounts for unexplained features of the low energy world, and gains credibility and confidence as a result. However, understanding the very early universe may require even more counter-intuitive thinking of concepts than quantum theory does, due to its distance away from the everyday world.

Despite new constraints on the possible nature of dark matter, it is still believed to exist in the form of particles, as our exploration of the parameter space is limited.

Summary
Despite new constraints on the possible nature of dark matter, it is still believed to exist in the form of particles, as our exploration of the parameter space is limited. This mysterious substance is thought to be responsible for the gravitational forces producing the same size confinement of galaxies, and its presence can be inferred through computer simulations.

A theory that applies to the early universe should explain features of the standard model of particle physics that are otherwise unexplained, according to a theoretical physicist, who emphasised that the early universe is even further away from the everyday world than quantum theory is.

Summary
A theory that applies to the early universe should explain features of the standard model of particle physics that are otherwise unexplained, according to a theoretical physicist, who emphasised that the early universe is even further away from the everyday world than quantum theory is. The concept of an even larger universe beyond what we can see is becoming increasingly accepted.

The universe likely contains much more than what we can see within our horizon, possibly a million times as much.

Summary
The universe likely contains much more than what we can see within our horizon, possibly a million times as much. Additionally, we know little about the depth of the universe and our mechanism of observation.
