I have a paradox that states mathematically, in the univere, a straight line cannot exist; however, it probably was thought of before me. That's the problem these days... hehe... no room for anymore ideas! A straight line may exist if it leaves the fabric of spacetime, but if it stays within the universe, and the universe curves, then the line will no longer equal 180 degrees, and thus is not a straight line. So, it depends on how you think about it. But as long as the line exists within the universe, it will not be a straight line.

This is my idea. It's not yet a theory or even a hypothesis; just an idea: What is time? Time is the fourth dimension. I've wondered if the fourth dimension could actually be visualized. I noticed on one of these threads, someonequestionedwhy we haven't seen people from thefuture in our time. My argument to that would be that the future hasn't occured yet, but maybe it has. I think that the 4th dimenstion(time) is divided intobillions of sectors, some of them further along in time and some behind us in time. Each one of these sectors evolves over time to be like the one ahead of it. Maybe time travel isn't possible. Or, maybe we will discover it so far in the future that we will only go just so far back into the past. Let me know what you think.

Really? Where did you read that? I guess I'll have to work really hard! Good luck at Cambridge! -Jennifer

You are a scientist? what field do you work in? I want to be an astrophysicist when I graduate. I would love to chat with you. Feel free to send me a private message. -Jennifer

Noah, Unfortunately I am only an amateur astronomer, but when I get out of school, I want to be an astrophysicist. I do study astronomy all the time. I'll be happy to dicuss astronomy-related topics with you! -Jennifer
