Astronomers have observed an anomaly in the eclipses of a binary star system. They suggest this could be due to the presence of two giant planets, orbiting the stellar binary.
The two stars, known as UZ For, are both smaller than our Sun. One of them is a white dwarf, the …

A researcher has suggested that dark matter might simply be an illusion, rather than some unknown non-baryonic matter. Assuming that antimatter has a negative gravitational charge, the “illusion” would be explained by the resulting gravitational polarization of the quantum vacuum by ordinary matter.
The need for dark matter first appeared with …
