Jason Steffens is an assistant professor of physics and astronomy at the University of Nevada, Las Vegas. What does cosmological redshift do to light? The cosmological redshift is a consequence of the expansion of space. The expansion of space stretches the wavelengths of the light that is trav...
The object is far outside our galactic neighborhood, possibly billions of light-years away. But astronomers have seen similar objects closer to home.
The orbit ofMercuryis shifting very gradually over time due to the curvature of space-time around the massive sun,according to NASA. As the closest planet to the sun, Mercury’s perihelion (the point along its orbit that it’s closest to the sun) is predicted to follow a slightly differen...

I lost my sight when I was four by falling off a box car in a freight(货物)yard in Atlantic City. Now I am thirty two. I can slightly remember what color red is. It would be wonderful to see again, but a disaster can do strange things to people. I might not have come to love...
Even if this method of timekeeping is novel in its particulars, early agricultural societies also connected time to natural phenomena. In pre-Classical Greece, for instance, people “corrected” official calendars by shifting dates forward or backward to reflect the change of season. Temporal connect...
