I say a load, because its not the top one. String theory is notoriously hard to solve any of the equations and make predictions. It has been said...
The matter comes from the energy thats what E= mc^2 is all about. The kinematics are determined by special relativity and the mechanics, i,e, what...

No matter how many 9's there are it isn't equal to 1. The = symbol represents something being equal to another. For the instance of a limit there...
No. 0.999=0.999, 0.9999999999=0.9999999999, 1= 1. Why not just say that 5000 = 1? If you round to the nearest then you have to present any results...
The annihilation of two gamma rays will result in the creation of two 512 keV gamma rays. This process can happen in reverse. An electron will...
You can create matter. Two photons can combine to create an electron if they have an energy greater than 1/2 the mass energy of the electron. So...
Thats not a bad little puzzle, I may set it as a question some time. Still struggling to see what it has to do with planes though.
Are we talking about the geometry of spheres or the flight paths of planes. Projecting a 2D plane onto a 3D surface is something that always plays...
I've not heard anything that severe but I agree that people could suffer, though there is more than global warming at work, we also have to fold...
Well as a rule its thought that we are looking for a macroscopic process to give time a direction as quantum phenomena tend to be time symmetric,...
Someone has to do the groundwork. If the Curies and Bequerel hadn't started messing around with radioactivity over a century ago, we wouldn't have...
I just realised I made that post so I may as well respond. I guess the first thing ill say it that i was trying to raise the possibility that time...
Magnetic Monopoles are very contentious. After doing classical electromagnetism and relativity most people take the very defensible position that...
I suspect that the way out of this little mess is that surprise is not either non-existent or total. But there is a range of degrees of surprise,...
I think all we know from the gravitational measurements is the planets size and probably some measure of its distance. By other measurements we'll...
Thanks for the relativity lesson, let me have a go at this relativity lark. One postulate of special relativity is that the speed of light is seen...
I don't think you will turn into pure energy at the speed of light. Though thats largely irrelevant as you wont get there. Quite beyond the...
When thinking about possible ways life can exist its hard to know whether your being limited by a lack of knowledge of other ways of making life...
Well the discovery does bring the count up to 2, not sure that qualifies as full. But I do agree that as its only 20 light years away it does seem...
