Synopsis: Mapping the Heavens provides a tour of the ''greatest hits'' of cosmological discoveries -- the ideas that reshaped our universe over the past century. The cosmos, once understood as a stagnant place filled with the ordinary, is now a universe that is expanding at an accelerating pace, propelled by dark energy and structured by dark matter. Priyamvada Natarajan, our guide to these ideas, is at the forefront of the research -- an astrophysicist who literally creates maps of invisible matter in the universe. She not only explains for a wide audience the science behind these essential ideas but also provides an understanding of how radical scientific theories gain acceptance.
From the Author:
How do you map the universe?
Explorers once understood Earth by mapping what they saw. If I only included visible objects in my map of the universe, it would show a mere four percent of the cosmos. Equipped with Einstein’s theory of general relativity, I use gravity to see how invisible “dark matter” bends light from stars and galaxies. This provides a remarkably detailed picture of the structure of the universe.
Is dark matter real?
Scientists know a lot about how dark matter is distributed in the universe and the critical role it plays in the formation of galaxies. Dark matter is mysterious because it lacks much personality—it interacts very weakly with ordinary matter (like you), it moves sluggishly, and it accumulates in lumps. You are right to be skeptical—the history of science is replete with abandoned invisible explanations (ether, miasma, and phlogiston)—but there is much evidence that dark matter is real.
Could a figure like Einstein exist today?
No and yes. Many fields are so specialized that it is hard to imagine one person making an Einsteinian impact. That said, the Internet makes it much easier for an outsider to garner the attention of the scientific establishment. Of course she would still need transformative, innovative, and radical ideas.
Where will we find the next radical scientific ideas?
We now have copious data in cosmology, neuroscience, genetics, and material science. Finding and comprehending meaningful patterns in that data will allow us to mine for fundamental principles and new frontiers for exploration. This is how I think we are going to find the next radical idea that could upend everything!
