The Overstreet Comic Book Price Guide (or Official Overstreet Comic Book Price Guide) is an annually published comic book price guide widely considered the primary authority on the subject of American comic book grading and pricing in the hobby/industry. Numerous observers connect the expansion of the direct market distribution system and the ...
Physical cosmology is a branch of cosmology concerned with the study of cosmological models. A cosmological model, or simply cosmology, provides a description of the largest-scale structures and dynamics of the universe and allows study of fundamental questions about its origin, structure, evolution, and ultimate fate.

Delayed until the end of World War II, the Red Book was published in 1946, providing collectors even more historical information as well as retail values (prices collectors could expect to pay coin dealers to buy coins) instead of wholesale values. R. S. Yeoman served as editor of the Red Book and Blue Book until he retired in 1970.
Astronomy portal. v. t. e. The Lambda-CDM, Lambda cold dark matter, or ΛCDM model is a mathematical model of the Big Bang theory with three major components: a cosmological constant, denoted by lambda (Λ), associated with dark energy. the postulated cold dark matter, denoted by CDM. ordinary matter. It is referred to as the standard model of ...
The Real American Hero series had spawned comic books and cartoons, and Hasbro hoped that the Hall of Fame line would have crossover appeal to the collectors of the 3.75" figures, and also the nostalgia appeal to the earlier generations that had grown up on the original G.I. Joe and the G.I. Joe Adventure Team. To accentuate that this figure ...

Using the values known in 2018 and Planck units for Ω Λ = 0.6889 ± 0.0056 and the Hubble constant H 0 = 67.66 ± 0.42 (km/s)/Mpc = (2.192 7664 ± 0.0136) × 10 −18 s −1, Λ has the value of = = = where is the Planck length. A positive vacuum energy density resulting from a cosmological constant implies a negative pressure, and vice versa.
