The Braneworld Theory

The braneworld theory states that in order for the universe to have survived, it would have had to create relatively small "black holes". Moreover, this theory can be experimented upon.

This theory suggests that we are in a three dimensional mem...

The Ekpyrotic Theory

The Big Splat also known as the Ekpyrotic Theory, was thought of by cosmologists Neil Turok and Paul Steinhardt who believe that eventually a brane would collide with another and through the collision there will be enough energy to creat...

The Cosmic Microwave Background (CMB)

The Big Bang to this day, remains to be a fan favorite of many scientists and with that theory comes two key observations: the expansion of the universe, and the cosmic wave background.

The CMB is thought to be the ...

The Holographic Universe

The Holographic Universe denotes the idea that the three-dimensional universe that we are used to could actually be a fundamental two-dimensional space.

So how it works is that there couble be a distant two-dimensional surface that contains the data that is needed to fully ...

The Steady-State Universe

The Steady-State Theory suggests that the universe's expansion happened due to the continuous bubbling of hydrogen atoms from an empty space at the rate of 3 hydrogen atoms per cubic meter million years.

This theory was first put forward in 1948 by British ...

Dark Matter and Modified Newtonian Dynamics

Gravity is the only force in physics that affects matter on humongously large scales however it can't, on its own, explain certain astronomical observations. 

There are two options that we could forego with: unseen dark matter - that provides for the missing gravity, or to ...

Four-Dimensional Space-Time

The universe may only exist in three dimensions but we can also visualize it having a fourth in the form of time, so to speak, the universe may exist in four-dimensional space-time.

This idea was proposed by Stefano Liberati from the International School f...

Self-Centered Anthropic Theory

The laws of physics hold a handful of fundamental constants that determine the strength of gravity, electromagnetism and subatomic forces. However, these numbers could have any possible value and with any value that gets displaced, the universe would be entirely different.

This argu...

Simulation Theory

This theory comes from the philosophers. It questions that if all of the information about the universe are input into our brains via our sense and other scientific instruments, who's to say that this isn't all just some cleverly constructed illusion?

This is a great argume...
