If youre going to suggest e The steep drop-off favors the merger of two white dwarfs because it predicts that most stars in the early universe are too young to become Type Ia supernovae. 93 billion light-years is only the diameter of the universe that we can see -- the visible universe -- reaches of the universe beyond this are concealed by the cosmic microwave background radiation, a field that is created by the hot plasma that was omnipresent in the first 300,000 years after the Big Bang. Not the observable universe, which is currently a sphere about 93 billion light years across and increasing all the time, but the much smaller portion that we could ever hope to reach. The visible universe is thus a sphere with a diameter of about 28 billion parsecs (about 93 billion light-years). A galaxy is just about the largest object in the universe. The observable universe is fixed at 13.7 billion light years in all directions from earth. How can that be when the universe is only 13.7 billion years old? If the universe is curved, though, it must be so colossal that the entire 93 billion light-years we can see isnt a large enough portion to reveal the curvature. One of the interesting things about the universe is that it is currently expanding. The Universe is getting smaller. It is unclear on how big it is, but a common answer that the universe is NOT infinite and is about 600 Billion Light years Across. A. Reset. As an illustraction, take the infinite 'universe' of the natural numbers i = 0 . The whole universe is at least 250 times as large as the observable universe. Also, how big is the universe compared to the Earth? So space is really big, but its not infinite. Here is how you can do it more effectively for the best results: Sleep. The age of the universe is about 13.75 billion years. Since the Universe is expanding, our cosmic playground is shrinking all the time. Only 4% of the universe is what we can actually see, stars, galaxies, planets, nebulae, etc.

More info available on wikipedia along with other cool info about super-clusters, filaments, voids, the Great Wall and the Great Attractor! Because space itself is expanding. There is a very common misconception about how the universe formed in the Big Bang: COMMON MISCONCEPTION: There The age of the universe is about 13.75 billion years. Furthermore, how many light years big is the universe? Scientists estimate that the observable universe, the part of it we can see, is around 93 billion light years across. So, the best estimate at the moment is that the edge of the observable universe is 46.5 billion light years away. The most distant thing we can "see" in our universe is the cosmic microwave background (CMB), the light of which has been travelling for about 13.6 billion years. It would take 93 billion years to cross what we know of the universe, but that hasn't happened, and we only have evidence that the universe is known to be only ~13.some billion years old. The universe is an object containing hundreds of BILLIONS of galaxies, nebulas, and more objects. Using the calculate speed of expansion, and the age of the light we can calculate that even though that light source was 13.8 billion light years away 13.8 billion years ago, it is now actually 47 billion light years away. And, after nearly 14 billion years of expansion since the big bang, the part of the Universe we can see -- the observable Universe-- is 93 billion light years across! The Andromeda Galaxy. Also, how big is the universe compared to the Earth? Continue Reading Adam Wu Question: We assume the universe is 13.7 billion light years old. via Wikipedia. The Incredible Shrinking Universe.

Edits thereto will be discarded in good faith. :-)] Its no secret that the universe is an extremely vast place. The distance is 6 trillion miles. The COBE data shows light from the very early universe. Multiply times 2, and you get 93 billion light years, the diameter of the observable universe. But can you imagine the expanding speed of the universe is faster than the light?

A logarithmic illustration of the observable universe. Hence the name Light Year. The universe is almost impossible to comprehend - 13.7 billion years old, 93 billion light years across and filled with over 100 billion galaxies, each containing hundreds of billions of stars. Doubling that gives you a diameter of 93 billion light years. What lies beyond that, we dont know we cant observe it in any possible way and were not really sure. As a reminder, a light-year is a unit of length equal to just under 10 trillion kilometres (or about 6 trillion miles).. During those 13.75 billion years, the universe was also expanding. 81 folds and your paper will be 127,786 light-years, almost as thick as the Andromeda Galaxy, estimated at 141,000 light-years across. Improve this answer. How can it be understood that the universe is 93 billion light years across and yet only 13.8 billion years old? [N.B. If youre going to suggest e The comoving distance from Earth to the edge of the observable universe is about 14.26 gigaparsecs (46.5 billion light years or 4.4010^26meters) i The size and age of the universe seem to not agree with one another. 93 billion years away 93 billion light years across - ANSWER 1 See answer Advertisement Advertisement alconextrem is waiting for your help. 93 billion light years . Its observable diameter is around 93 billion light-years and the universe was formed 13.7 billion years ago. Inflation is the answer, the universe got 10^78 times more volume in 10^-32 seconds. Crazy, but it has passed all the test so far. Inflationary exp 93 billion light-years 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..

Our universe is expanding with accelerating speed. radius of 13.8 billion light years only. It has an estimated 350-billion large galaxies (like the Milky way).

You may already know just how massive the universe is, stretching 93 billion light-years in diameter. Additionally, how big is the universe compared to the Earth? So what is the distance in miles that light can travel in a year, making up a light year. That is a diameter of 93 billion light-years. We will never see the light from objects that are currently more than 15 billion light years away, because the universe is still expanding. Despite the fact that the universe is vast approximately 93 billion light years across, galaxies still manage to run into one another. Though the age of the universe is around 13 billion years only. The Earth is about 3.5 million times larger than a human. This series explains the vast phenomena of deep space by re-examining the familiar on Earth. According my understanding it could have a max. There are two ways you can tap into cosmic energy. It has an estimated 350-billion large galaxies (like the Milky way). Now combine those two sets to get an expanded 'universe' and you obtain the natural numbers again. This means that the light that reaches us today from the background has traveled for 13.75 billion years to get to us. I take it that you're starting out in SR. Special relativity is "special," because it is a special case of GR, namely that there are no gravitational fields or accelerations, and that space is flat and static. The age of the universe is about 13.8 billion years. Note that each light year is the distance of which light travels in a year, or about 6 trillion miles. So the total number of stars is 10 22, which represents a huge number to make anyone amaze. So the earliest light we see is from roughly that time. This is just to give my inference, from the The teams preliminary evidence shows a sharp decline in the rate of Type Ia supernova blasts between roughly 7.5 billion years ago and more than 10 billion years ago. According to Cosmologists and Advanced Union Physics, there are other realities (Parallel Universes) which can be reached by That is See: http://scienceblogs.com/startswithabang/2009/07/31/the-size-of-the-universe-a-har/ This is an explanation of the size of the observable univer It is an unnecessarily confusing description of the size of the universe. Yes, it's due to the space expansion (about 70 km/s/Mpc).
