Well well I see this is a topic to be discussed. Oxygen is an oxidiser huh? Whats that high school physical science class. Bush has proposed a mission to Mars by 2020, but has no earthly idea on how to get there. I have submitted a few other topics to this forum but I feel the best about this...
Whats sup Tweet
I guess it would be fun to live in the imagination. As long as you were able to return back to the real world. Then you would not need a time machine.
If he went back in time and could not come back then his trip back in time did not work it was just suicide. That is not a time machine. The purpose of a time machine would be to go back in time, do whatever it is you have went back to do, and return home. Then there would be no proof needed. Is...
I had you .
I had you, but I lost my whole reply. 4000 characters down the drain.
Well thought out and articulated. I was just getting started good too. To sum it up I said the Mantle was kept at a constant temp. Heated by friction and cooled by cracks in the Earth's crust. I mentioned the...
What would a person need to do or show us to prove he is a traveler from the future. What would be the key piece of evidence that says, hey this guy is for real.
To me his technology as a whole should speak for itself.
But if?
But if that Apache Pilot fley back in time to WWII With information from the future the craft itself would be evidence. John Titor Had a shot Gun(not even a good one just some old chrome sawed off pump) and a Corvette. I can soup up a vette. Also he would know how his vehicle worked so...
Time Travel it's bout as logical as space travel
It is possible that a person was sent here to prevent some great catastrophe, but let's just be real. B.S military documents and pictures of some contraption you would find in radioshack(a well stocked Radioshack). We are sceptical by nature...
I love intellegent conversation
Sorry for the mistake. Heat IS the movement of molecules. Also a very good argument for Radioactive Decay. Maybe there is not just one source of heat, I believe that the amount of heat transferred down by plate movement ie friction between the two would be...
Pretty good
If you told me that the Earth was hollow I would say okay, Back that up with facts.
Theories should be proven. The statements I made were all facts.To disprove my theory would require facts of your own. The Cores heat is not generated but stored in the mantle. The illustration you...
Thank but No.
That was a cute website a lot of valuable information for my sons science fair project in which he won first place this past summer, but the skin of an apple is thick enough to hold in water just as the crust is thick enough to hold in heat. The only relevance that has is the...
Core Heat hmmmmmm. let's see.
Friction&Pressure.Duh huh. Now let's go deeper. Stop looking at the core and look at the mantle. The core is hot always been hot. The reason it won't cool is because it is surrounded by the perfect insulator(ie.molten rock). Then on top of that we have our...
Space Planes
Well First off we already have an orbital space plane with great payload capacity. The question is not do we need one, because that answer is yes. The question is should we commercialize it. The answer is not yet. When I read this post the first thing came to mind was unnecessary...

This is my first post to the physics forum and I see my input is well needed. First off Fossil fuels are like fossils they are history. We can't even get into orbit without tons of the stuff. O2 as a fuel Is just a band-aid on a larger problem. Sure it is lightweight such as hydrogen but since...
