It is true what is on black it is just a word i agree with you but if you compare really the math itself ( put on the side the word) at the universe no start with 0 and 1- ++++ and no end
Yup our radio telescopes tell us that our Universe (the big bubble that we live inside of which contains everything that we can see including all stars and galaxies) started somewhere in some direction with a big explosion and continues in all directions at increasing speeds.
This is only possible according to the laws of physics that we know of if (1) the force at the middle propelling everything outwards is STILL THERE emitting force, and (2) there are no other forces outside of the bubble to STOP it.
That's all that we know about it -- precious little else.
We must learn to live with uncertainty.
Okay, as the big bang is also an uncertainty.
What would have caused this explosion coming for nowhere ?
Where is the center of the Universe?
The universe has no center, because it has no edge. In a finite universe, space is curved in such a way that if you could travel billions of light years in a straight line, you would eventually return to your starting point. It is also possible that our universe is infinite. In both cases, groups of galaxies completely fill the universe and move away from each other at all points, following the expansion of the universe
An example of a tiny universe containing only 48 stars. A spaceship traveling among these stars can not find the edge of this universe. If it goes out through one side of the universe, it will reemerge through the other edge. The travelers aboard the ship see an infinity of stars all around them. This universe has neither frontier nor center.
(Where did the Big Bang take place in the Universe?
It is often said that the Big Bang was an explosion in an empty space, and that this explosion developed in this empty space. This is false.
The Big Bang created space and time. At the beginning of the universe, space was completely filled by matter. The material was originally very hot and very dense, it then expanded and cooled to end up giving the stars and galaxies that we see today in the universe.
Although space may have been concentrated at a single point at the time of the Big Bang, it may also have been infinite from the beginning. In both scenarios, space was completely filled by matter at its inception.
There is no center for this expansion, the space 'swells' at all points. An observer in any galaxy sees most of the other galaxies in the universe moving away from him.
The only answer to the question "Where did the Big Bang take place" is thus that it occurred at every point of the universe.
Is the Earth also expanding in the universe?
The Earth is not expanding, nor is the Solar System, nor the Milky Way. These objects were formed under the influence of gravitation and ceased to expand. Gravity also retains the galaxies in groups and clusters. It is mainly groups and clusters of galaxies that move away from each other in the universe.
What is outside the universe?
Space was created by the Big Bang. Our universe has no edge or boundary - there is no 'outside' to our universe (see question 1). It is possible that our universe is only one of an infinity of universes (see question 4), but these universes do not necessarily need a 'space' to exist.
What was there before the Big Bang?
Time was created by the Big Bang - we do not know if it existed before the Big Bang. However, it is very difficult to answer such a question. Some theories suggest that our universe belongs to an infinity of universes (called a 'multiverse') in perpetual creation. This is possible, but extremely difficult to prove.
If the universe is 14 billion years old, how can galaxies be more than 14 billion light years away?
It is probable that our universe is infinite, and filled with matter everywhere since the Big Bang (see question 2). There is also serious evidence that in the early days of the universe, the universe had expanded at a much higher rate than light. It is possible to create such an expansion, in which the particles do not move at high speed but where the space between the particles increases considerably.
We can imagine galaxies as balls laid on a sheet of rubber that represents space. If we stretch the sheet, the balls move away from each other. Two close balls will only move slowly. Very distant balls will appear to leak at high speed. There is no limit to the rate of expansion of space.
Space is the geometry of our universe. Changes in the size or shape of space can occur due to shifts of matter or energy in the universe, or because of changes in the universe's content in terms of matter and energy.
