This is not currently known. There does exist some asymmetry between matter and antimatter - meaning that they are not exact opposites in all aspects - but this asymmetry is not enough to explain why matter exists.
Under current understanding the Universe will be around for trillions of years - too many to even count or worry about.
scientist belive they have found another planet in a other universe with some sort of life
Why is it advantageous for astronauts to live on a space station rather than in a space shuttle
Current scientific meaning of the word universe, is that it includes everything. So there is only one universe - The Universe However the new idea of String Theory is starting to suggest that there may be more than one universe, and so the meaning of the work universe may change in the future. The scientist Brian Greene is one of the leading physicist working on this theory. Science-teacher
The word 'universe' may be defined as follows: NOUN 1) everything that physically exists; all of space and time together with matter, energy, and forces that are governed by the laws of physics; the natural or material world in which we live; nature; the cosmos 2) a reality that is separate and different from our own with its own dimensions of space and time and governed by its own natural laws 3) all people living on planet Earth; society; mankind; the world 4) planet Earth together with all its living creatures 5) the huge cluster of stars, gas, and dust of which planet Earth is a part; the Milky Way; the Galaxy 6) in logic, all items considered for discussion; a universe of discourse 7) in statistics, all the elements from which samples can be taken; a population 8) a sphere of activity, interest, or influence involving a person or a group of people
Sir Issac Newton had three laws of motion, which all concerned matter. The first was the law of inertia: an object is either still or moving at a constant speed, and will stay either moving or at the same speed unless acted on by an external force (such as friction - this is why you cannot slide forever on concrete). The second was the law of force: F=m*a (where F=force, M=mass, and a=acceleration). The third was the law of conservation of energy: for every action, there is an equal and opposite reaction (this is why, if you push off of the floor with your feet, you will go up - commonly known as jumping).
The physical environment is composed of matter, energy, space, and time. It is synonymous with the world or the universe in which we live.
In science, 'universe' denotes the physical continuum in which we live consisting of matter and energy arranged in four dimensions of space and time. It can also denote another such continuum hypothetically separate from our universe with its own dimensions of space and time and its own arrangement of matter and energy.
It is not currently known whether there are other planets with intelligent life... or with any type of life for that matter. It does seem likely, considering the huge amount of stars in the Universe, most of which seem to have planets.
The natural order of the universe is innately harmonious and well-organized. When people live according to the laws of the universe, they live in harmony with that universe and the natural environment.
