"Dark Energy's Role in Black Hole Binaries and the Observable Universe"
A chart created by Dr. Charles Lineweaver and graduate student Vihan Patel plots everything in the universe, from subatomic particles to superclusters, on a log-log graph of mass and radius. The chart reveals a black line that separates the area forbidden by gravity from the space populated by familiar objects, with black holes dotted along the line. Interestingly, the entire observable universe, within the Hubble radius, falls on this line, suggesting that if a black hole were as large as the observable universe, it would have the same density. This raises the question of whether the universe itself is a black hole. However, the assumption that everything outside the Hubble radius is a zero density Minkowski space complicates the implications of the chart, leaving the question open for further exploration.
