How long would it take to walk across the Universe?
It is currently unknown if it is even possible to walk across the universe because the universe is constantly expanding and its size is beyond comprehension. Even if it were possible, the sheer vastness of the universe, with its estimated diameter of 93 billion light-years, would make it an impossible journey for any human being.
If flying at light speed for an Eon is it possible to go beyond the universe?
The universe is about 90 billion light years across. An eon is about 550 million years. Flying at the speed of light for 550 million years you would travel 550 million light years, less than 1% of the distance across the known universe. So, probably not. It would make no difference how long you travel at light speed. If you travel for a billion trillion eons, you would still not pass through the boundries of the universe. For one thing, you would have a serious problem timing your journey, since for you a trip of any length would seem instantaneous.
How long would it take a light beam to go across a galaxy 50000 light years in diameter and return?
It would take 100000 years.
How many miles across the universe?
The universe is 78 billion light years in radius, 156 billion in diameter. 1 light year is how long it will take you to travel at the speed of light so if it's 78 billion light years in radius then it would take you 78 billion years to travel that far. Also people have said that if you go far enough the number of partial combinations will run out and you will start to see exact replicas of the world you know and love.
How long would it take to travel from the end of the universe to Earth?
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.
Why was light year invented?
It is a simpler way of measuring very long distances, which is what we have in the Universe.
How long does it takes light traval across the diameter of earths orbit?
It takes about 997.186 seconds for light to travel across the diameter of Earth's orbit.
How many miles long is space?
The observable universe is about 29 gigaparsecs across. You'll have to convert to miles yourself.
Can gravitational force act at a distance?
If it didn't everything in the universe would have gone flying apart long ago and there would be no universe!
Why would it take long for alpha centauri light to reach earth?
Alpha Centauri is 4.37 light-years away from Earth, which means it takes light, the fastest thing in the universe, 4.37 years to travel that distance. Although light travels at a speed of about 186,282 miles per second, the vastness of space makes this journey take years.
Giva an example of a non testable hypothesis?
A test to find how long it would take to send a 100 ton space ship at the speed of light, to the very end of the universe. 1) An object at the speed of light has infinite mass and would require infinite fuel. At present both of these are impossible to test. 2) The end of the universe changes frequently, by the time the ship reached the end, the end would be further away, and the universe also grows at varying speeds.
What happens when you reach the edge of the universe?
The Universe is approximately 14.6 billion light years across (radius), which gives a total of around 30 billion light years from edge to edge. The Universe came to exIstence 14.6 billion years ago and has been expanding ever since. The expansion process occured very rapidly and exponentially, resulting in expansion close to the speed of light, 3 * 10^8 meters per second. Therefore, the edge of the Universe, from the center, would be around 14.6 billion light years away, theoretically. It turns out that these theoretical calculations are accurate, as astronomers have recently detected the light from stars around 14 billion light years away. As the Universe ages, it will expand even more quickly due to the effects of dark energy.
