“A new dark force?” | The daily galaxy

Everything we know about the universe and all the laws of physics applies to four percent of the universe. The other 96 percent are unknown dark matter and dark energy phenomena. “If we take into account all the matter and energy we are familiar with,” says Neil deGrasse Tyson, “and measure how much gravity it should have, it is one …

SpaceX’s satellite Internet service latency is less than 20 milliseconds

(Image credit: SpaceX) According to SpaceX, the Starlink satellite internet service has achieved a latency of less than 20 milliseconds, which is equivalent to ground-based broadband. SpaceX included the data in a presentation sent to the FCC last Friday that was discovered by Reddit users. The two benchmark tests carried out with Ookla’s Speedtest.net service show that Starlink has a …

Experimental treatment preserved muscles in ‘Mighty Mice’ in space

Scientists say experimental treatment helped “powerful “Mice” maintain healthy muscle mass within a month during a recent visit. Treatment could one day prevent muscle and bone loss in astronauts during long periods of time in space. It could also be used to treat people suffering from muscle or bone loss on earth. Astronauts in space live in a microgravity or …
