Has science proven which stars are legally not allowed to have comets on them or is that part of the new grant they are preparing to investigate laws in space?

Let's say I have an ant farm that I started say 10 years ago.
Let's say I applied radiation and/or other factors to cause the ant farm to evolve at an accelerated pace. (Assuming I developed the technology to do this)
This evolution turned 6 legged 1/8th inch black ants into 8 legged 1 inch green spiders and this evolution took 10 years.
Lets also say that I had a preservative in the soil so that the bodies of the animals would not decompose.
What would I find in the soil when I dug it up at the end of the decade?

...and is everything now neatly sorted out? or are we still confused about supposedly basic stuff like gravity?

Each numeral series stands on its own.
Their relationship is among the first/second/third numbers.
The relationship is the same for each numeral series.
But each numeral series does not affect each other.

Sorry for this tired conversation...I was having a debate and I was wondering what are the actual facts that evolution happened. I know there has to be something beyond theory. Have any examples or facts to prove evolution?

I was watching television a few days ago and there was a show on about how scientists think love is not real. They think it is a chemical reaction in the body and it happens to trick you into thinking you love someone, so you will stay with them long enough to mate and continue the human species.
What do you think of this?
I believe this is probably somewhat true, but I also believe love is very real.
