Hitchhiker's Guide to Space-Time

Our Past, Present and Future

In this course, you’ll get to learn the ever-evolving story—the history of everything—in its monumental entirety from the moment the Universe grew from the size of an atom to the size of a galaxy in a fraction of a second.

More is unknown than is known. We know that roughly 68% of the universe is dark energy. Dark matter makes up about 27%. The rest - everything on Earth, everything ever observed with all of our instruments, all normal matter - adds up to less than 5% of the universe. Yet we still do not know how ordinary matter survived against total annihilation by anti-matter.


The expansion of the Universe started acceleration about 7 billion years ago and the Universe is being ripped apart. The reason is Dark Energy, a mysterious energy multiplying in vacuum. We will talk about the evidence behind these startling discoveries and discuss what we may learn in the near future. And one of the biggest elements of the universe is - Time. Understanding time is the genesis for understanding our existence.


This course consists of four lectures and is offered in English. Each session would be of 50 minutes, followed by a one to one Q&A session. 

Price: Rs 600 per lecture

Recommended Age Group: 14+ years

Course Overview


Before and After Big Bang: How it All Began?

Knowing Cosmos

We will take a journey from our local Earth at the present time all the way to the edge of the universe and back to its birth, learning the processes and findings in modern physics that provide us this understanding. In this session, we will understand how all the stars, planets, solar systems, galaxies, we see today, have originated from a "Pinhead". This is what we call the Big Bang Explosion.


Matter - Anti-Matter and Their Interaction

Ingredients of Big Bang

In this session, we will learn about dark matter and anti-matter -- some of the more mysterious sides of the Universe. We know Dark Matter played an important role in the formation of stars and galaxies, but many properties are still unknown to us. In another strange mystery, we will see how the beginning of the universe started with equal amounts of matter and anti-matter, yet somehow only matter survived.


The  Mysterious "Unknowns" of our Cosmos

Potential Habitable Worlds

Universe has entered into a stage of expansion, considered to be caused by Dark Energy, a mysterious energy multiplying in vacuum. In the vast garden of the universe, we also have the most fascinating region of spacetime where gravity is so strong that nothing—no even light—can escape from it. In this session, we will discuss all such mysterious "unknowns" which surround us (some of them are yet to be observed!).
