Hace 2 días · The time following the emission of the cosmic microwave background—and before the observation of the first stars—is semi-humorously referred to by cosmologists as the Dark Age, and is a period which is under intense study by astronomers (see 21 centimeter radiation).
Hace 3 días · Hubble's law, also known as the Hubble–Lemaître law, is the observation in physical cosmology that galaxies are moving away from Earth at speeds proportional to their distance. In other words, the farther they are, the faster they are moving away from Earth. The velocity of the galaxies has been determined by their redshift, a shift of the light they emit toward the red end of the visible ...

Hace 5 días · The basic relationship between the distance, speed and time that is $d = v \times t$ will help approaching the problem. Formula used - $\mu = \dfrac{c}{v}$, $d = v \times t$ Complete step-by-step answer: Given data: Thickness of the glass slab = t Refractive index of the glass slab = $\mu $
Hace 4 días · Data. The GOES X-ray plots shown here are used to track solar activity and solar flares. Large solar X-ray flares can change the Earth’s ionosphere, which blocks high-frequency (HF) radio transmissions on the sunlit side of the Earth.
