The expansion of the universe is the increase in distance between gravitationally unbound parts of the observable universe with time. It is an intrinsic expansion; the universe does not expand "into" anything and does not require space to exist "outside" it. To any observer in the universe, it appears that all … See more

The simplest scenario of an expanding universe would be one in which R increases with time at a constant rate. But you already know that life is not so simple. The universe contains a great deal of mass and its gravity decelerates the expansion—by a large amount if the universe contains a lot of matter, or by a negligible amount if the universe is … By precisely determining the expansion rate, called the Hubble constant, the cosmic clock can be rewound and the age of the universe calculated. However, Edwin Hubble's estimates of the expansion implied that the universe was younger than the age of the Earth and the Sun. Hubble, therefore, concluded that the redshift phenomenon was an unknown ... What does it mean when they say the universe is expanding?

It can’t be static. After 30 years of meticulous work using the Hubble telescope's extraordinary observing power, numerous teams of astronomers have narrowed the expansion rate to a precision of just over 1%. This can be used to predict that the universe will double in size in 10 billion years. The measurement is about eight times more precise than Hubble's ...Oct 28, 2016 · One of the criticisms the new paper levels at standard cosmology is that the conclusion that the Universe is accelerating is model dependent. That's fair enough. Usually cosmologists are careful to say that we are studying 'dark energy', which is the name we give to whatever is causing the apparent acceleration of the expansion of the Universe.
