When the Universe was a tiny dense ball of matter, how much matter did it contain? Did it contain the exact amount of matter needed to make the Universe as big as it is today (and bigger as it's still expanding)? How would it know how much matter is needed? Does every object I see before me have a past of once being inside that dense ball of matter, or was matter created to fit the Universe's size when it began?

This is something that happened to me almost 10 years ago. I lived in Norway at the time(where I was born), and I hav'nt told anybody about this since that time. I did tell my parents and my brother, but they laught if off, so I have not spoken about it since. I lived just outside of a town called Stavanger in North Norway, and we lived in a small hamlet with 14 houses, a postoffice and a phonebox. We even had to be bussed to school in Stavanger itself, because the school that had been in the village had closed before I was born. My favorit past time as a kid was fishing, and there were ice on the water most of the year. As soon as I got home from school, and all day Saturday I used to go out, huck a hole in the ice and start fishing. Now, this happened on the 7th of November(I remember it so clearly, because it was on the day after my brother turned 18). I went to one of my favorite spots, and started to make a hole in the ise. Suddenly there was a strong white light coming >>> cont.

Is it because of the prehistoric glacier activity? Do people that live there experience selenium deficientcy even though the U.S. has a national food market so most of the food they eat may not be grown in selenium deficient soil? My friend takes selenium supplements and is recommending them because we live in Ohio.

In "Finding Nemo," a huge school of large fish are caught in a net. They escape when Nemo instructs them to all swim downwards, overloading and breaking the fisherman's crane, which projects out horizontally over the water. Assuming fish would do this, would it work? Give the fish every benefit of the doubt. This is, after all, a kids' cartoon.

From physics, we know that when a figure skater is spinning and pulls her arms in, her rotational velocity increases (to conserve angular momentum) However, the rotational kinetic energy increases. So my question is, where does this extra energy come from? I read that it is from biochemical potential energy (from your muscles), but I am not sure if this is correct. Thanks in advance! :)
