Big Bang (before & after), Dark Matter and Dark Energy: a breath-taking story of our Universe.

Join me in a cosmology adventure across space and time! It starts "before" the birth of our Universe: a fluctuation of an inflaton field caused a Big Bang (eternal inflation theory). This event gave birth to our spacetime, particles, matter, stars, planets but also to dark matter and dark energy.

This video is the starting point of a new series that will focus on cosmology.

In this new series, we will discuss dark matter: why we strongly suspect its existence, how we can detect it, and the hypotheses on what it could be.

Then, there is the issue of Dark Energy, that triggers a force causing an acceleration of the expansion of our Universe. What is its nature? and why is it here?

These questions need answers: all we know about our Universe is based on 5% of its content only. Thus, if we discover one day the nature of Dark Energy and/or Dark Matter, it should deeply shake our understanding of reality.

Searching for these answers have made scientists develop ways of thinking that are stunning of ingenuity. In the end, the old adage “the journey is more important than the destination” applies extremely well in Physics!

Of course, Physics Made Easy does not have any definite answers to these questions, but this channel has the goal to put you on the path where you can derive your own opinions, while at the same time learn about some awesome physics.

I hope you enjoy the Journey!

Disclaimer: Please note that the story of the Universe from the Big Bang till today is based on a theory which is consensual with most of the scientific community. The idea of an Inflaton field occurring before the Universe is more controversed, and even considered speculative by many scientists. One origin of this pre-bigbang inflaton field is anthropic in nature: all the values of the universal constants appear fined tuned for observers like us to exist. the chances of this occurring by random are microscopic. So why? The idea is that all universes with all combinations of constants actually exist, and of course, we happen to be in the one where observers like us can live.
