how much is the universe

The universe as a whole can be compared to this ball. The running counter of known … The universe (Latin: universus) is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy.While the spatial size of the entire universe is unknown, it is possible to measure the size of the observable universe, which is currently estimated to be 93 billion light-years in diameter. The radius of the visible Universe is estimated at 1.7e26 m (18 thousand million lightyears) plus or minus 20 percent or so. The observable universe spans some 28 billion light-years (93 billion light-years in diameter, as it is still expanding). When it comes to exoplanets that have been measured or counted in some way, the numbers are much smaller. This NASA page and this " Extension, Age and Mass of the Universe" article discuss different techniques that scientists use to estimate the mass. If the Universe is 13.8 billion years old, and the speed of light is truly our cosmic speed limit, how far away should we be able to see? If the primary content of the universe is inert matter, as in the dust models popular for much of the 20th century, there is a particular fate corresponding to each geometry. The mass of the universe is a source of debate right now because there is no easy way to put the universe on a scale. UK Contact: Claire Bowles claire.bowles@rbi.co.uk 44-207-331-2751. Because there are approximately $10^{11}$ galaxies in the Universe, we get $10^{101}$ bits of entropy carried by the galactic black holes which is much higher than the CMB entropy. Cosmic holographic bound on entropy Press Release From: New Scientist Magazine Posted: Wednesday, December 13, 2000 . Hence cosmologists aimed to determine the fate of the universe by measuring , or equivalently the rate at … Now, the size of the observable universe is about 14 billion light years, and using the above value of density gives you a mass (dark and luminous matter) of about 3 x 10 55 g, which is roughly 25 billion galaxies the size of the Milky Way. By studying the greatest structures in the universe, scientists reveal exactly how much of the universe we still can't fully account for. The next question is, "How much matter does the universe contain?" We are currently living approximately 13 billion years after the universe's start, but, given the different scenarios for its demise, it's unclear how much longer the universe will persist. It is home to about 10-billion superclusters (like the Virgo Supercluster). Initially, before the big bang, the universe-ball was at rest. The mass density of visible matter (i.e., galaxies) in the Universe is estimated at 3e-28 kg/m^3 (3e-31 times the mass density of water). How much does the Universe weigh?
