We cannot know for sure, but we're sure that the universe expanded faster than the speed of light. While it is physically impossible for any object to move through space faster than the speed of light (according to Einstein's theory of relativity), it is possible for space itself to expand faster than the speed of light since it is not an object, but the area in which all objects and laws of physics are contained. In fact, space is still expanding faster than the speed of light.
The short answer is about 71 km/s/Mpc (kilometers per second per megaparsec).
The value that expresses this is the "Hubble Constant", first measured by Edwin Hubble when his studies of galaxies indicated that the Universe was expanding. His original figure was far too large, due to the incomplete state of relevant knowledge at the time, but modern understanding and measurement (including observations made with the Hubble Space Telescope, named after him), have narrowed it down.
The Universe is expanding because space is stretching. What this implies is that the more space there is between two galaxies, the faster the expansion of the Universe is carrying the galaxies apart. So the relevant question is: for a given distance between two points, how fast is space stretching between them?
The distance unit astronomers use on this scale is the megaparsec, or one million parsecs. A parsec is about 3.26 light-years (a light-year is a distance -- it's the distance light travels in a vacuum in one year).
So if there are two galaxies one megaparsec apart, how fast is space stretching between them? The best current measurements, from several sources, all give answers in the area of 71 kilometers per second, so we say that the current value of the Hubble Constant is about 71 km/s for every megaparsec of separation, or 71 km/s/Mpc.
Note that this is the value of the Hubble Constant today; due to the ongoing effect of something called "dark energy", the rate of expansion of the Universe is increasing. This means that the value of the Hubble Constant is not really constant, but is actually getting larger with time, albeit at a rate that is far too small to affect observations over human time scales.
The Universe is not expanding. The Universe is in equilibrium. The idea that the Universe is expanding results from a mis-interpretation of Hubble's redshift measures and the Biblical Creation Story. Einstein observed that the universe was not contracting under gravity and added a cosmological constant to "account" for the lack of contraction. This cosmological constant is an anti-gravity feature that adds expansion. mathematicians claimed that Einstein's Equations only allowed for expansion or contraction. When the redshift was discovered the deal was sealed. Hubble did not interpret the redshift as an expansion, he called it "an hither to unknown principle of nature". Hubble was correct and the current view of expansion is wrong. There is a herd mentality in physics like in Stock Market Bubbles. The Big Bang is a Bubble, there is no expansion.
So quickly that no matter how fast you went, you could never catch the edge of it.

The "Big Crunch" idea was that the expansion would eventually stop and the universe would collapse. All evidence today says no way. The "Yo-Yo" says the universe repeatedly expand, collpses and then expands again of a roughly 70 billion year cycle. There is no evidence for this. The "Big Rip" says the universe will simply expand forever, with other galaxies gradually getting so far away that they fade in the distance, and then stars burn out and everything gets cold and dark forever.
Well, since the end of the Universe is constantly expanding, and since it would depend on how fast you are going, it could take 1 year to 10000000000000000000000 years or more. There is also very little evidence that the Universe actually has an ending.
I didn't check the year... But the cosmic background radiation is said to support the big bang theory, because it agrees with the radiation that is expected from an expanding Universe.

The Sahara is currently expanding south at a rate of up to 48 kilometers per year.

Through the process of desertification, the Sahara is growing rapidly each year.

Miss Universe is an American organization, but it is held somewhere different each year. Miss Universe 2014 was held in the USA.
How much what is generated each year
A light year is the distance that light can travel in a year.
Each year, Miss Universe will live stream the event on their website. The show can also be watched from your home live.
In the Milky Way galaxy, around one star is born each year and around one star dies each year. Throughout the universe, around 100 billion stars are born and die each year.
