NASA Jet Propulsion
Laboratory reported that the astronomers who work with the Space Telescope,
"Spitzer", were able to conduct a more accurate calculation of the
rate of increase in the history of astronomy. In other words, this swiftness is
called the Hubble constant.
We live on a small
planet Earth, but this does not preclude our interest in the rest of the world.
But to know the size of this huge, compared to us, the world, to find out what
the age and expansion rate of the universe has. More recently, you can also add
the concept of "acceleration of the expansion." But the accelerated
expansion of the universe, you can still stick to the linear Hubble law.
