Has the big question about the origin of the universe finally been answered?
No. We have some theories that explain important aspects about how the Universe began. The current theories and understandings that we have get to fractions of second after the beginning, but we still have not gotten to the beginning yet. As to any purpose of the universe, science has not attempted to even discern such a thing.

What in astronomy is a thousand million years?
A trillion years is 1,000,000,000,000 years. In astronomy, it is probably a meaningless concept, because according to our current understanding of the universe, space and time began with the Big Bang around 14 billion years ago. So, looking back, there is no 15 billion years or more in astronomy. Looking forward, there is too much uncertainty about the amount of matter in the universe to judge whether it will continue to expand and eventually burn away, or reverse into a big crunch which may be followed by Big Bang 2. However, there will be no link between our universe and universe 2. So whichever way it works out, current theories suggest that the universe as we know it will not survive a trillion years. So many questions to answer, so little time!

Who proposed big bang and universe is expanding explain?
The history of the Big Bang theory began with the Big Bang's development from observations and theoretical considerations. Much of the theoretical work in cosmology now involves extensions and refinements to the basic Big Bang model.

How did the universe begin according to the best scientific theories?
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.
What is the meaning of theories of the origin of the universe?
The origin of the universe is just that - a theory. We can only speculate how universe began - based on the knowledge we have up to now. There may be other factors - that could change our perspective on how the universe began - yet to be discovered !
What year was potassium made?
Potassium is an element... it was created when the universe began, which, according to current theories, was between 13.6 and 13.8 billion years ago. Unfortunately, science has not discovered the specific date that the Big Bang happened. However, for the sake of the prompt, I will hazard a guess... June 23rd, 13,700,000,001 B.C.E.
How can observations about the universe be so exact when virtually all of the light to make these obsevations was less than 200 years away at the time that careful observation began?
More importantly than where the light was when precision astronomical measurements began is where/when the light originated from. Since the light samples a large range of space and time we can make useful and accurate cosmological observations.
What happened to universe right after big bang?
It began to expand in size. There is a hole at that point in our knowledge of the early universe but without a doubt the universe began to expand.

How and why have the scientific theories of earth changed?
Science is an ongoing process. Every day, scientists are doing research. They are performing experiments, and observing the natural world, and working on various forms of theoretical explanations for what they have observed. New observations and new logical analyses will lead to new theories. This process began with Galileo, and it is still taking place.
