I found this chart here: http://sci.esa.int/science-e/www/object/index.cfm?fobjectid=36827&fbodylongid=1729 and it has adjacent galaxies listed with a factor that says "R.A." (relative age?).....how would you go about reading it?

Thank you very much for your help. I will look into all of this information in the near future. Thanks again!

Can someone point me towards some links or sources that would help me explain how to estimate the relative age of galaxies and how to estimate the adjacent galaxy's ages. Thank you.

I am trying to contact either Hydroponicists or people that work with vegetation for a Science Fair Project. All I want is a few questions to be answered...very broad and general questions about hydroponics, nothing very specific. Thank you very much if anyone is able to help me either with the questions or find a Hydroponicist. Just please tell me if you are able to answer these questions, and I will contact you if you may be able to give me contact information. I spend a lot of time looking this up on Google.

I would like to research the effect of magnetism on plants, which does have a proven effect, but there is no explanation of why this happens. Also, the idea of Solar Light vs Artificial Light is a good area to reaseach also...but I am not sure how either will turn out.

Hello. I am doing a required High School level Science Fair exhibit. I am planning on using this subject as the main focus. The problem is that I do not know whether electricity has any adverse effects on vegetation, and therefore I am not going to take any chances to see if it does anything or if it just sits there. So I am wondering whether anyone knows if electricity does anything to vegetation. I looked on google, and I am having a hard time sifting through the results. If no one can give me an answer, can someone please give me another reccomendation for a High-School Difficulty project? Thank you.
