The universe began approximately 13.7 billion years ago. The big bang theory describes how the universe was created, and began to expand rather rapidly.

If gravity dominates the expansion of the universe what would happen to the universe?
It would begin to collapse inwards towards its most massive points until finally it all met at one point, according to some theories.
When did the universe begin to expand?
As soon as it began its existence (13.7 billion years ago).
How did the universe started?
Science has advanced to the point where we can infer something about the entire universe. This has been a great challenge considering how unimaginably vast the universe is. The countless stars you see in the darkest sky constitute merely 3000 neighbors out of about 300,000,000,000 stars in our galaxy, and as many as 100,000,000,000 galaxies exist in the universe. Humans have always wondered: Has the universe always existed like we see it now, or did it somehow start all of a sudden? In the beginning of this past century, we found out in amazement that the entire universe is expanding. This led physicists to deduce that the universe started out in the finite past with a minuscule size. Realizing that the universe had a beginning, and awed by its vastness and its creations, people have asked: How did the universe begin? After all, we are here to be amazed by it because the universe eventually created lives like us. Now, after decades of observing and thinking, we have come to answer confidently the question of the origin of our universe... with what is known as the "big bang".
When did time begin according to Einstein's view?
When time began was not determined by Einstein.
When did universe begin where is the end?
We have no way of knowing the answer. Will the universe ever end at all? Again, we don't know. Right now, we suspect that the universe may expand forever; we cannot "see" enough mass to cause the expansion to slow down. But then, we can't see enough mass to keep the Milky Way together; it is spinning entirely too quickly for the mass that we know about to generate enough gravity. Some scientists have postulated some form of "dark matter", and perhaps even a corollary "dark energy" to account for the mass we cannot see. If there is enough (and if it exists at all!) then the universe may, perhaps, slow its expansion and collapse into itself, at some unimaginably distant date in the future. But we're guessing, and scientists try not to guess. Much.

What is inductivism?
According to inductivism, scientific research proceeds from observations to theories.Scientists begin with experiments, finding out what happens in specific cases. They then use the results of these experiments to develop general theories about what happens in all cases.
Are theories ever changed?
Theories are changed constantly. In fact, many known theories today are only theories from that of someone else only with an improvement. Many scientific theories for example are developed that way. Take this for example, many thought the world was flat, that theory developed (changed) to the fact that the world is round instead of flat. Current theories that are changing daily-- "How was the universe formed?" "How did life begin"? "Was there ever life on Mars"? "What is all that DNA for?" "How do we make more efficient solar cells?" "What will happen with global warming, and how can we modify it?"
If a scientific theory changes does this mean that it was not a good theory to begin with?
No. It means that it was the best theory supported at the time it was formulated. Theories can change if new scientific evidence provides new information.

When did time begin according to Einstin's theory?
None of the theories proposed by Einstein deal directly with when time began
What is the definition scientific question?
The definition of a scientific question is a question that can be answered using experimentation and factual reasoning. Some examples are:What is the universe made of?How did life on earth begin?What is consciousness?What is at the bottom of the ocean?

What are the different theories of personality?
There are four main types of personality theory. Begin with biological theories, behavioral theories, psychodynamic theories, humanist theories and trait theories.
Why do scientific theories change?
Non-scientists might think that changing a scientific theory means it was wrong. The theory may or may not have been wrong. Scientists are usually not upset when they have been found to be incorrect. Here's why-- Science is the best way humans have of explaining the world. Theories change all the time as smaller issues get resolved and revisited. Adjustments and changes to theories are common. When new tools get introduced (such as a bigger telescope), scientists know that theories will change and new discoveries will be made. Current theories that are changing daily-- "How was the universe formed?" "How did life begin"? "Was there ever life on Mars"? "What is all that DNA for?" "How do we make more efficient solar cells?" "What will happen with global warming, and how can we modify it?" For some of these we have pretty good ideas, for some of these there are major puzzles. But it is the best we know how to do.
When the big bang theory when did the universe begin?
The current theories of the big bang suggest an age of any where from 13.5 Billion and 14 Billion years old. The generally excepted figure is 13.8 Billion Years Ago.
How did the universe begin in judaism?
God created it.
