where our technology can't yet reach. way way out. I'm talking very intelligent, not nessicarily humans, but people/alien things that have smart advances like we do on earth, and are thinking the same thing we are. trying to find each other.
its a thought that really gets me exited. lol.
I do believe that there are little living organisms on other planets but I'm saying intelligent life,

and where does the universe end? can you keep going up and up and up and never end. spooky.

Which two liquids should i compare for my sci. project?

I am doing water rockets. I was going to put water in Rocket A, and put Milk in Rocket B, and see which one went higher.

I hypothisized that Water would go higher since it had a lower density.. but no I'm hearing that milk and water have similar densities.. so there wont be much of a difference in the heights of the rockets..

So now im thinking to compare Rubbing alcohal vs. Water..?

Is there a difference in densities for these two liquids?

Which two liquids should i compare?

Any other ideas?

Although I read somewhere that when its exposed to oxygen it oxides, I'm not sure how to answer this question, but I have it for a chemistry lab. "Although calcium is a metal according to its position on the Periodic Table it seemingly lacks luster. How can this be explained?"
Any ideas?

Hello, I know that question sounds stupid, but let me explain first. I know how to use telescopes fairly well and have been for years, but last year I was given a small 4.5" reflector scope that a friend didn't use any more, and I can't seem to get a crisp image with it at all. When looking at stars or planets I can never get it to focus sharp. where it should be sharp it has a fuzzy halo around the star/planet and you just see a blob of fuzz. It's so bad that I can't see the rings of Saturn or the cloud belts on Jupiter. I've checked and cleaned all the mirrors and eye pieces and they seem to all be in good condition. No scratches or anything that I can see. Any ideas on what's causing this or what I might be able to do to remedy this would be greatly appreciated. Thanks for your time and help.

Im very curious with these questions and they are on my mind :)

Theres a little bit for each type of paranormal enthusiast and the non-believers!

Have you ever lived in a haunted house but learned to deal with it?

For those who haven't had a paranormal experience in their home:

1.do you agree with someone selling a home and saying it's doesn't contain paranormal activity, but it does and they just lie to the people they are selling it to? (i know it is illegal to sell a home with that , just want opinions)

For the other Paranormal Investigators:
1.What is the most legit piece of evidence you have recieved from an investigation

For the Skeptics: ANSWER BOTH OF THE FOLLOWING
1. What do you need proof in order for ghosts to exisit.
2.Where is the/your proof they don't?

~Please do not come on here saying ghosts don't exist if you do please answer questions one and two under for the skeptics~

With anything, let it be ghosts, demons, murder movies, anything. It frightens us, yet we love watching the videos, shows, and movies about it. I know, I would be deadly afraid if something were to happen, yet I love watching horror shows. If I saw an alien in real life, I would be deathly afraid, but I love watching movies and looking it up online.

Anyone else feel this way? And why are humans amazed when it comes to the paranormal?
