The five strongest signals corresponded to planets with Neptune-like masses, between 13 and 25 times that of the Earth. These planets, with orbit periods ranging from six to 600 days, are separated from their star at 0.06 to 1.4 times the distance between the Earth and sun. Dr Lovis added: ”We also have good reasons […]

Well organized tables showing the names, symbols, and magnitudes for most of the physical constants you'll ever need to us There are many physical constants in science, some of the most widely recognized being the speed of light in vacuum c, the gravitational constant G, Planck's constant h, the electric constant ε0, and the elementary charge e. Physical constants can take many dimensional forms: the speed of light signifies a maximum speed limit of the universe and is expressed dimensionally as length divided by time; while the fine-structure constant α, which characterizes the strength of the electromagnetic interaction, is dimensionless.
