In a recent episode of The Ranveer Show, I had the privilege of hosting Dr. Annapurni Subramaniam, a renowned astrophysicist and the director of the Indian Institute of Astrophysics. Our conversation spanned a range of topics, from the mysteries of the universe to the practical implications of space research in India. The insights and knowledge shared by Dr. Annapurni not only deepened my understanding of astrophysics but also highlighted the immense potential and challenges in the field of space science.
Orion’s Belt and the Pyramids of Egypt
During our discussion, I mentioned the only part of astronomy I truly understand – Orion’s Belt. Its three stars, aligned in a straight line, are easily identifiable. Dr. Annapurni enlightened me about the spiritual conspiracy theories that suggest a connection between Orion’s Belt and the alignment of the pyramids in Egypt. Interestingly, these stars, though they appear aligned to us, are not at the same distance from Earth. The ancient Egyptians used the rising of Orion in the East to predict the flooding of the Nile, which was crucial for their agriculture and calendar.
The Enigma of Black Holes
We delved deep into the topic of black holes. These cosmic entities are regions where the gravitational pull is so strong that even light cannot escape from them. They remain invisible, and their presence is often detected indirectly. For instance, when a star orbits an invisible black hole, it provides evidence of a massive entity contained within a small volume, leading to the conclusion of a black hole’s presence.
The Role of Astrophysics
Dr. Annapurni explained that astrophysics is a blend of astronomy and physics. While astronomy is the ancient science of observing the sky and its patterns, physics helps explain the reasons behind these patterns. For instance, why does the Sun emit light and energy continuously? Why doesn’t the Moon produce its own light? The answers to these questions lie in the realm of astrophysics, which also involves mathematical calculations to understand orbital dynamics and other celestial phenomena.
Impact of Asteroids
One of the significant concerns in space science is the potential impact of asteroids. These celestial bodies, if they collide with Earth, can cause catastrophic damage. Understanding their trajectory, size, and composition is crucial for devising strategies to mitigate potential threats. Dr. Annapurni emphasized the importance of continuous monitoring and research in this area to ensure the safety of our planet.
Space Tech Startups in India
We also touched upon the burgeoning space tech startup ecosystem in India. With advancements in technology and increased interest in space exploration, several startups are making significant strides in satellite technology, space travel, and research. Dr. Annapurni expressed optimism about the future of space tech in India, highlighting the potential for innovation and collaboration.
Discovering the Unknown in Our Solar System
One of the intriguing parts of our conversation was the discussion about the unknown aspects of our solar system. While we have a fair understanding of the planets and their orbits, there are still mysteries to be unraveled. There are theories suggesting the presence of another planet or entity exerting gravitational pull, which is yet to be discovered. The continuous quest for knowledge in this field is what makes astrophysics so fascinating.
