Video - Cosmic Wonders and Human Marvels: Speed of Light, Mars' Giant, Brain Evolution, DNA Resilience, and Galactic Collision!

"The speed of light in a vacuum is an incredible 299,792,458 meters per second. This fundamental constant is the ultimate speed limit of the universe and forms the basis of Einstein's theory of relativity." "Olympus Mons on Mars is the largest volcano in the Solar System, standing nearly 22 kilometers (13.6 miles) high. This colossal mountain is almost three times the height of Mount Everest." "Over the past 10,000 years, the human brain has shrunk by about the size of a tennis ball. Despite this reduction, our intelligence has not decreased; it may even reflect increased efficiency." "Human DNA is remarkably fire-resistant, meaning it does not ignite easily. This resilience helps protect our genetic information even under extreme conditions." "In approximately 4 billion years, the Milky Way will collide with the Andromeda Galaxy. This cosmic event will create a new elliptical galaxy and transform our night sky."
