Dark matter

Sorry, my fault, but still, referring to your earlier post, we are not all experiencing and moving through space at the same speed. Some people are moving through space faster and slower than others.

I can agree. I flaw in this design is it does not show the curvature of space and time. Instead, you can look at like this; you have at first a perfectly flat dining room table with a cloth over it. You draw perfectly straight lines crisscrossing like a graph. (as described in my previous post) Now, in order to show the curvature of space and time you can take the cloth off of the table and throw it randomly on the floor. This imitates space because the lines should theoretically be a perfect graph, but when you throw in forces and energy, it clumps up and there are more lines in some places and less in others. The Elegant Universe Written by Brian Greene... Good book I would (and probably antimatter) recommend it.

Catapult.. I would like to keep this rather simple A bit.. this is just a simple science project, and the main objective is just to use three simple machines. I would say we only need to be able to launch like a 5 pound object about 30 feet, although being able to launch a tennis ball 75 feet would probably get us an A... "Bought this trebuchet as a kit several years ago, and put it together over the Memorial day weekend" Kits are lame..

What? It's extremely possible to make and do calculations required to simulate the gravity on earth. However, it is unpractical to make a space station like that because of costs and such. And why even make a space station like that in the first place when one of the most prized possessions of entering space is no gravity?

Me and my science "buddy" are building a catapult for science class and I was wondering if anyone had any suggestions for a basic design. (dimensions should be about 3' high and 2' x 3' for a base. All Suggestions are greatly appreciated...

Space is infinite yet finite. I look at it much like a really big coordinate plane with an x, y, and z axis because numbers on a grid never end.

But an observer can see time move faster on someone else.

most physicists and Astro-physicists believe that there is intelligent life in the universe because of the massive numbers of galaxies and planets. However; some biologists refuse to believe intelligent life exists because of how many things have to be perfectly right for a planet to hold intelligent life. In my opinion, I think the thought of intelligent life is a very real fact.

Time travel is possible. In fact, you are traveling through time right now, except you are just traveling forwards not backwards. Although traveling backwards may be a bit harder, it's still theoretically feasible. -David Goldstein

I personally prefer analog because it feels classic and it makes me feel I guess... closer to my watch. Another reason why i like my watch is because it teaches me discipline. The reason? I don't want any reminders or beeps coming from my watch to tell me when lunch time is, or when an appointment starts. I like to feel like I need to do things on my own and say if you forget your watch one day and you don't have that beeping? You don't know when lunch or that appointment is. Anyway, take no offense digital-users I mean no harm. Either way any Geek holds their watch, computer, and calculator close to their little Geek hearts... -David Goldstein *note - this post does not have any merit and does not make much sense.

I think this would feel incredibly... disjointed because the magnets would have more effects on some parts of your body than others. It's much easier to simulate a gravitational field with centrifugal force.

And then this continues until the black hole loses all of its Gravitational potential energy? So then this process happens over and over and over again until the black hole loses its energy..?

Wouldn't the black holes either cancel out or evaporate? Otherwise, that's a really neat concept. Maybe you could make a black hole binary in order to keep them from canceling out... Just a thought.

Technically, there is not shape of the universe since there is nothing out side the universe.

I like your theory. I believe that a black hole acts almost as a paradox upon itself by gaining objects, which then gain other objects and so forth.

Recently, me and my friend had a conversation about Black Holes and why they evaporate. I have read about Black Hole evaporation and know some; however, the books that I have read do not completely explain evaporation and how it works. If you have any information, feel free to share.

Black holes form from supernovae, and they get bigger because they build on themselves, for instance once you "suck in" another celestial body, then you gain more gravity and keep on gaining more and more mass and gravity. Correct me if I'm wrong.

isn't Jupiter not entirely made out of gas, and has a central core?

I am curious, what type of matter is it? (responding to martin)

It's slang for signature... I think.

When you mean observable universe, do you mean what we can see with waves, or what anything can see. Woa, major headache from reading this.

Hahaha

Question: if the universe was expanding into something, wouldn't that just be part of the universe?
