Because all of science's theories are based on assumptions. Just study up on the Philosophy Of Science.
they wont answer for ever
Science cannot ever solve social problems, and doesn't try for that reason.
It is, but so is gravity. In science, 'theory' means 'idea that has been proven over and over and is generally accepted as truth'. It's a pity it doesn't mean the same in everyday language. ^^
Yes, in fact nothing in science is ever considered to be 100% without a doubt factual. Gravity is a prime example in the sense that we're not starting to question if gravity is even real because we can not observe it.
he was the best scientist the world has ever known
All the time. Science is the act of questioning everything, including what you already think you know.
Now why would you ask that, there is nothing on the internet that will ever give you that answer
None ... there is no danger in doing this, at least nothing has been ever proven against this practice.
No. Nothing has ever been found that can influence sexual orientation.
That is an interesting question, and a very difficult one to explain. Science has always been in existence, ever since the beginning of the universe. But since humans evolved, we have been discovering new branches of science almost all of the time.
Yes it should be so nothing dangers would ever happen and that is for your own safety
It can not be proven they ever had one.
Cancer is the result of natural phenomenon. The purpose of science is to explain natural phenomenon. Therefore, science is used to explain cancer. Medical care is considered a scientific field. Every doctor you have ever known has undergone extensive training in scientific knowledge and methods. Doctors who treat cancer, oncologists, are scientists too.
There is some evidence that Martin Luther King, Jr. was unfaithful to Coretta. However, nothing has ever been proven nor will there likely be.
Nothing has ever been manufactured that could move anywhwere near the speed of light, and according to the best current science, nothing in nature can ever move faster than the speed of light.
No one truly knows, scientifically. In many religions, Adam was the first human on Earth. But nothing has been proven.
If they are proven to exist, and then the process is clearly defined then they would no longer be paranormal they would become a part of the natural world. There is no reason to think they aren't a part of the natural world now, it is just that science can't explain or quantify it. Thus making it paranormal. At one time things we know as perfectly natural were at one time paranormal. Even lightning in the prehistoric times to primitive people seem to them like magic.
