Japanese astronomers have performed long-term multiwavelength observations of a supernova remnant (SNR) designated SNR G298.6−0.0. They found that G298.6−0.0 is an old SNR interacting with molecular clouds. The new findings ...
In 1916, Einstein finished his theory of general relativity, which describes how gravitational forces alter the curvature of spacetime. Among other things, this theory predicted that the universe is expanding, which was confirmed ...
