General relativity describes spacetime as a smooth, continuous fabric that dynamically curves in response to mass and energy. While widely accepted, it remains incomplete due to the presence of singularities.
In recent years, observations of our nearest galactic neighbour, Messier 31 (M31) or the Andromeda galaxy, have identified that the system has undergone a tumultuous history.
One of the key questions in modern cosmology is determining the precise value of the Hubble parameter (H₀), which describes the linear relationship between an object's recession velocity and its distance.
I have been fascinated by the night sky since I ‘discovered’ Saturn with my 60mm refractor at the age of 10. An APOD-winning astrophotographer, I have been published in Sky & Telescope, Astronomy Magazine, and Space.com. As a NASA Solar System Ambassador, I have conducted thousands of public outreach programs and am a registered cruise ship speaker on astronomy and space science, as well as a Director of the Phoenix Astronomical Society. I frequently post astrophotography images, news, and tutorials on social media. My solar imaging and videos are particularly popular, and I have conducted extensive research on solar cameras and solar image processing techniques.
