73.5 million million million metric tons. or 7.3477 x 10^22 kilograms
Answer:
La distancia media de Venus al Sol es de 108.159.260,51 Km
La distancia media de la Tierra al Sol: 149.597.870,691 Km
La diferencia entre una y otra distancia media te dará el promedio de distancia de la Tierra a Venus: 41.438.618,181 Km.
Siendo la velocidad de la luz: 299.792,458 Km / seg
Divides: 41.438.618,181 Km / 299.792,458 Km / seg = 138,22433 segundos
138,22433 seg / 60 seg = 2,30374 minutos
Este tiempo es el que tarda la onda de radio en viajar del planeta Venus a la Tierra.
La velocidad de la onda de radio se conviene en considerarla igual al de la velocidad de la Luz en el vacÃo.

Answer:
The Cosmic Microwave Background radiation, or CMB for short, is a faint glow of light that fills the universe, falling on Earth from every direction with nearly uniform intensity. It is the residual heat of creation--the afterglow of the big bang--streaming through space these last 14 billion years like the heat from a sun-warmed rock, reradiated at night.
Since the early twentieth century, two concepts have transformed the way astronomers think about observing the universe. The first is that it is fantastically large; the portion of the universe visible today is a sphere nearly 15 billion light-years in radius, and that, we believe, is just the tip of the iceberg. The second is that light travels at a fixed speed. A simple consequence of these ideas is that as you look at more and more distant objects, you're seeing farther and farther back in time--sometimes very far back indeed. When you see Jupiter shining in the night sky, for example, you're looking about an hour back in time, whereas the light from distant galaxies captured by telescopes today was emitted millions of years ag0.
