“Staggering” –The Implications of Infinite Space


Hubble Constant


“If space is truly infinite,” observes Dan Hooper,  head of the Theoretical Astrophysics Group at the Fermi National Accelerator Laboratory, in At the Edge of Time, “the implications are staggering. Within an infinite expanse of space, it would be hard to see any reason why there would not be an infinite number of galaxies, stars, and planets, and even an infinite number of intelligent or conscious beings, scattered throughout this limitless volume. That is the thing about infinity: it takes things that are otherwise very unlikely and makes them all inevitable.”


“Pac-Man Black Hole Mergers” –Could Explain Origins of the Cosmic Web of Galaxies

“This could be a unique way of probing the physics around these supermassive black holes in a way that could not be probed in any other way,” said theoretical gravitational wave astrophysicist, Rochester Institute of Technology’s Assistant Professor Richard O’Shaughnessy, about simulations that could explain the origins of back hole mergers. “It offers unique insight into how the centers of galaxies grow, which is of course essential to understanding how galaxies as a whole grow, which explains most of the structure in the universe.”


Antimatter Galaxies –“Could Create the Most Destructive Event Since the Big Bang”

“Just because we happen to live in a region that is overwhelmingly dominated by matter doesn’t preclude the existence of other regions of space that are instead dominated by antimatter,” observes Dan Hooper, head of the Theoretical Astrophysics Group at the Fermi National Accelerator Laboratory (Fermilab) and Associate Professor of Astronomy and Astrophysics at the University of Chicago.


5,000 Robotic Eyes –“Probe the Unknowns of Dark Energy”

“I have absolutely no clue what dark energy is. Dark energy appears strong enough to push the entire universe – yet its source is unknown, its location is unknown and its physics are highly speculative,” said physicist Adam Riess in an interview. Riess of Johns Hopkins University is one of three researchers just awarded the Nobel Prize for Physics for their part in the discovery that the expansion of the universe is accelerating.


“Wormhole at the Milky Way’s Supermassive Black Hole”

“If you map the expected orbit of a star around Sagittarius A*, you should see deviations from that orbit if there is a wormhole there with a star on the other side,” Dejan Stojkovic, professor of physics, University at Buffalo, who proposes in a theoretical study, that perturbations in the orbit of stars near supermassive black holes could be used to detect wormholes forming passages connecting one area of our universe to a different time and/or place within our universe, or to a different, alien universe.
