Science ka Adda Episode 2: Do you know where you live?

The search for our identity starts at home. But how do we define home?

In this episode of Science ka Adda, we search for our cosmic address, starting from Karachi and ending with some of the farthest galaxies discovered by astronomers. Such an exercise immediately provides a humbling perspective in light of the sheer immensity of the universe. We may be worried about the day-to-day happenings on a relatively small portion of the Earth, but in some ways, these are pale in comparison to the known universe that contains more than hundred billion galaxies, each containing a hundred billion stars.

Our sun is just one of these stars.

But what is truly amazing is that inhabitants of a planet orbiting an ordinary star located in the outskirts of our galaxy have discovered their cosmic address.

Join me on Science ka Adda in searching for our place in the universe.
