As others have said, you cannot copyright ideas. However, that is not really what you want to achieve here is it?
What you really want is to be credited with coming up with the ideas in the first place in the event that either you or someone else is able to do the science to prove them right. It's the recognition you want.
If you want to profit from the exploitation of your ideas, then you would need to come up with a method of exploiting them and copyrighting, patenting and otherwise protecting the exploitation.
My suggestion would be to publish as widely as you can. Write a self-published book; create a blog; physically print everything off and post (mail) it back to yourself so you have date proofs.
A suggestion: read the history of how Charles Darwin came to publish his internationally famous On The Origin of Species and then ask yourself why you have never heard of Alref Russel Wallace.
The key is not to procrastinate but to publish, publish, publish. If you do not blow your own trumpet, no-one else will and - worse - others may gain the credit for what you have done.
Finally, it is highly unlikely that the ideas you have are unique to you. Others may well be thinking along similar lines. There is never a perfect moment to go public, never a moment when you have everything carefully marshalled together. In the real world, there is intense competition in every aspect of life ... so act now, act fast and work out how to support your ideas later.
