To understand all of time and space is to leave no stone or dark stone unturned. A key element of this is understanding the current state of the universe, and how time has progressed. Our minds work in minutes or hours or days or years, but the Earth has operated on millions or billions of these time units, and it takes perspective to see broadly. Scientists bring this broad perspective to what they do because truth has no boundaries.
Is there a regularity to the extinction events of the Earth? What is the dark matter and energy that comprises over 90% of the universe made of? How do we examine that which can’t be seen using current equipment? This is the domain of Harvard theoretical physics Professor Lisa Randall. She discusses these topics in her book Dark Matter and the Dinosaurs, and has discussed other universal issues in previous books. Her list of accomplishments is longer than the DNA in all your cells connected end to end.
In Dark Matter and the Dinosaurs, Professor Randall takes us through discussion about comets, meteroids, our solar system as part of larger pieces that are still yet small pieces of the entire, somewhat flat, universe. She discusses past extinction events, and how comets or asteroids are sent hurling over large distances, with the word large being an understatement. Dark matter is discussed extensively, and you come out with an idea about the content that we are not able to see, but which is the majority of everything that is.
