Jan 5, 2016 · Nothing, at least as far as we know. The most distant reaches of the visible universe, the known universe, sit some 45 billion light years away. They are early constellations and stars. Problematic to that is the fact that they are moving away from us and that motion is accelerating. This 45 billion light years away is in all directions possible from our galaxy. But you have to consider that we live in a universe that is approximately 13.8 billion years old and accept the fact that nothing ...
May 21, 2016 · 1. The meaning of the word universe. Universe literally means all existing matter and space. So that excludes any other existing matter and space. Any existing other matter and/or space would fall under the definition of this universe and so be part of it. 2. The word is. If it is meaningful to speak of something beyond our universe, then what ...
Jan 13, 2016 · Explanation: The observable universe extends 45 billion light years in all directions. However, that does not mean there is more of our universe to be found beyond that distance. As of now, it is about as far as we can "see." That may well be the boundary of our universe or it may extend for another 45 billion light years, we just do not know.
How many stars are in an average galaxy? How many galaxies are there in the observable universe? One estimate is that there are 1010 stars in the Milky Way galaxy, and that there are 1010 galaxies in the universe. Assuming that the number of stars in the Milky Way is the average number, how many stars are in the universe? How do astronomers ...
Is the universe expanding in one direction? Edwin Hubble discovered the universe was expanding by measuring the light of distant stars, and by showing that those distant stars were moving further away from the earth. If this is so, then why is the Andromeda Galaxy moving closer to us? Why is the universe expanding? How can it do that?
Aug 14, 2017 · The "observable" Universe is literally that. All that we can see and measure. Outside of that we have no idea. As time goes by we can see further and further and it appears that more of the Universe becomes visible, leading to the hypothesis that there is more and more Universe to see, but we have no way of knowing what exactly is beyond our sight.
Mar 19, 2018 · As the universe expands matter and energy will become increasingly spread out and diffused. Eventually matter will become so spread out that there will be no matter only energy. Energy will move to the lowest possible level where there is no usable energy left. The universe will have effectively ended. It is expanding into nothing. Technically ...
Aug 13, 2017 · No, the noun "universe" is a common noun. A common noun is only capitalized when it is the first word in a sentence. The noun universe is a common noun as a general word for space and everything that exists in it, including the Earth and all the other planets; a general word for a particular sphere of activity, interest, or experience; a word ...
Mar 25, 2018 · Debatable. In mass, matter, and energy yes probably finite. In time and space, infinite. The Universe is expanding ( in fact is increasing in its rate of expansion) This means that the universe will continue to expand creating more of the space, time, matter and energy continuum. The first law of thermodynamics is that matter and energy can not created or destroyed. This would mean that the amount of matter and energy the universe started with is the amount of matter and energy that the ...
Apr 12, 2018 · Explanation: The universe as we know it is constantly expanding at an accelerating rate making a sort of boundry of where the universe ends. If there really is one is unknown and it's probable that the universe continiues forever, just in empty space. It's hard to know if the universe has an end as we can't just go there and see for ourselfs.
