Scientists Study Dense Molecular Gas in Circumnuclear Disk of Ultraluminous Infrared Galaxy

Huge reservoirs of molecular gas are found in ultraluminous infrared galaxies (ULIRGs), which are powered by starburst activity and usually with supermassive black holes that tend to accumulate material at their nuclei.

Research Breaks the Warp Barrier for Faster-than-Light Travel

If travel to distant stars within an individual's lifetime is going to be possible, a means of faster-than-light propulsion will have to be found. To date, even recent research about superluminal (faster-than-light) transport based on Einstein's theory of general relativity would require vast amounts of hypothetical particles and states of matter that have "exotic" physical properties such as negative energy density.
