Do you think that everything is a coincidence? With our current understanding of the Universe, we were able to found out that we need a certain amount of dark energy, …
Inflation is our solution! Earlier, we learned that there are four main problems about the Big Bang Theory: Initial density perturbation Flatness problem Horizon problem Monopole problem All these problems …
The three main evidences that the Big Bang happened are (1) the expansion of the universe, (2) the Cosmic Microwave Background, and (3) the Big Bang Nucleosynthesis. Despite knowing these, …
The Big Bang Nucleosynthesis (BBN) is a phase a few minutes after the Big Bang, which created the light elements (namely deuterium, helium and lithium). Combining the BBN theory and …
When cosmic microwave background (CMB) was first discovered, no one knew that it was actually CMB! Many scientists have dealt with studying CMB in its infant stages of research. Due …
The first 1000 seconds that shaped the Universe is called the Big Bang Nucleosynthesis (BBN). In this brief moment, a lot of things happened in the particle scale. Together with …
Let us continue our discussion about the future of the Universe. What will happen to our Universe after 100 billion years from now? After one googol (10100) years, will there …
Have you ever wondered what will happen to our Universe in the next millennium? In this two-part video, Prof. Goto will tell us a story about the future of the …
So which is faster? Expansion of universe or speed of light? Place your bets, everyone, as Prof. Goto will now reveal the answer to this question in this video. Let …
