Great & funny show guys. @warzan
From Wikipedia,
1. A lightyear a unit of astronomical distance equivalent to the distance that light travels in one year, which is 9.4607 × 1012 km (nearly 6 million miles).
I read Hawkins’s a brief history of time. Hardly understood a thing.
2. The galaxy
The Milky Way is a barred spiral galaxy that has a diameter usually considered to be roughly 100,000–120,000 light-years but may be 150,000–180,000 light-years. The Milky Way is estimated to contain 100–400 billion stars, although this number may be as high as one trillion. There are probably at least 100 billion planets in the Milky Way. The Solar System is located within the disk, about 27,000 light-years from the Galactic Center, on the inner edge of one of the spiral-shaped concentrations of gas and dust called the Orion Arm. The stars in the inner 10,000 light-years form a bulge and one or more bars that radiate from the bulge. The very center is marked by an intense radio source, named Sagittarius A*, which is likely to be a supermassive black hole.
3. The term dwarf star refers to a variety of distinct classes of stars. The term was originally coined in 1906 when the Danish astronomer Ejnar Hertzsprung noticed that the reddest stars—classified as K and M in the Harvard scheme—could be divided into two distinct groups. They are either much brighter than the Sun, or much fainter. To distinguish these groups, he called them “giant” and “dwarf” stars, the dwarf stars being fainter and the giants being brighter than the sun. The scope of the term “dwarf” was later expanded to include the following:
• Dwarf star alone generally refers to any main-sequence star, a star of luminosity class V.
o Red dwarfs are low-mass main-sequence stars.
o Yellow dwarfs are main-sequence (dwarf) stars with masses comparable to that of the (Sun).
o Orange dwarfs are K-type main-sequence stars.
• A blue dwarf is a hypothesized class of very-low-mass stars that increase in temperature as they near the end of their main-sequence lifetime.
• A white dwarf is a star composed of electron-degenerate matter, thought to be the final stage in the evolution of stars not massive enough to collapse into a neutron star or undergo a Type II supernova—stars less massive than roughly 9 solar masses.
o A black dwarf is a white dwarf that has cooled sufficiently such that it no longer emits any visible light.
• A brown dwarf is a substellar object not massive enough to ever fuse hydrogen into helium, but still massive enough to fuse deuterium—less than about 0.08 solar masses and more than about 13 Jupiter masses.
the game Scythe looks good reminds me of the BBC show tripods
