How exactly does gravity work on earth, does it come from the atmosphere or from within the earth? If it comes from the atmosphere how does it keep us down and what exactly is making it push us down to stay on earth? If it comes from within the earth how does it pull us down and when we get in high altitude does the gravity get weaker and if it does, would we weigh less? If it doesn't, how does it keep a standard pressure on our bodies holding us down throughout all altitudes? Thanks for any information, just started thinking about that and was wondering so thought I would ask.

So I know this girl, we talk, text, flirt, and hang out (by ourselves) a lot. She knows I like her, when she learned I liked her she didn't act any different around me (just smiled a lot more), then on christmas she called me and said she wanted to hang out so we did and we were talking and she brought up some guy and started saying she wanted her to ask him out and said she was going to hang out with on New Years Eve and they were gonna start going out, well, that never happened. She hung out with some of her friends so I am think ok. The thing is we were texting all the time and then tuesday she just stopped texting me all the sudden. I didn't do anything I just text her and she didn't text back and I text her a couple days later and she didn't reply again and she has never done anything like that before and we would text all the time. We would both start the conversations so it isn't like she just replied so I wouldn't feel bad. I don't get why she did this, we didn't have an argument or anything she just stopped texting me all the sudden. The thing is that she acted like she liked me before this and I was actually was gonna ask her out Christmas day until she brought up that guy, kinda glad I didn't do it earlier then but what I would like to know is why is she doing these things driving me crazy? Thanks for any info.

I like this girl that I go to school with and I thought she liked me but now I'm not too sure, she is single and I want to ask her out but I also don't because I don't want to make things weird between us. We talk quite a bit at school and text, we have also hung out a few times (by ourselves). She used to talk to me all the time and now she doesn't talk to me as much. But I'm a freshman in highschool and sadly have never had a girlfriend and I'm kinda shy. I would like to know how to get over my fear of rejection if you can help at all. Thanks

I think this girl at school likes me but I am not sure. She is always talking to me and wants to do something after school. She wasn't always like this, just here recently. She is always playfully hitting me and sitting by me whenever she can. I don't know if she likes me or not, any information is apprciated.
