I would have to say "thought". My idea is that thought become things, they become matter that we experience. and so our thoughts whether it be negative or positive, will draw atoms together to create our experience of that thing. Just like thought, there are billions of possibilities existing at the same time on different levels, like energy. Thus, there are parallel universes happening at the same time.
However, being that we are physical those thoughts have a time barrier, that enables us to chose and re-chose. All the tools of electromagnetisim and general relativity are created by atoms, which combine to form a larger scale. The nucleus of those atoms contain thought. Like attracts like.Like thought attract like things or experiences.
General relativity and electromagnetisim are tools that are constant in the physical realm, that bring balance.Atoms are the energy that make things seem whole,but in fact, are constantly moving at a rate that we think something is there,but is not.

If I grow radish seeds in a germination BAG, (which is basically a plastic bag) is light a major factor in the seed's growth? (there will be 10 seeds in 5 bags each representing a different level of the independent variable, I chose light) The reason I am asking this is because in the teacher 's directions, it says hang the bag on a cabinet door or in another location if the ind. variable requires it. I was going to put the control as the reg. day/ night cycle, one in comple darkness for 10 days, one bag of seeds which gets 1 hr. of sunlight a day, another for 2, etc.. Does this sound ok? And can light be my independent variable if they are grown in bags? If this is not a good idea, what can my independent variable be?

Let's say there was a gigantic mirrior in space, one light year from earth, and angled directley at it! Supposing you could build a telescope cabable of focusing on this mirrior, would it be possible to view earth as it was one year in the past?

This is all hypothetical obviously, so please don't start nitpicking at little details! I just want to know! thanks!
