1. ### Any ideas or solutions?

I have a problem of where to start on this equation. sqrt(x^2-x-10) = 10 + sqrt(x^2 - 11x) Solve for x.

3. ### Quantum fluctations and singularities.

Can one say that it is the same factors (whatever they may be, I don't know) in M-theory/String theory that puts away the effects of quantum fluctations, and also puts away the need/possibility of a singularity in a black hole? I see a connection since M-theory sets a limit of size (planck-...
4. ### Problem and a paradox

You must also remember that the mass is relative to an objects resting mass divided by the square root of (1 minus (v^2/c^2)). Taking this in account you get that as an object gets closer to c, its mass will increase, and thus the spaceship won't really be able to travel by the speed of light...
5. ### Quantizing speeds with the cosmological constant

Yes, Marcus, it was this kind of discussion I wanted. Thank you. However it would also be interesting if someone who knows Livine's work could answer (I remember you mentioned someone). If the theory is accepted and furthermore taken in account in today's other big bang theories, I believe...
6. ### Sequences - factorial r, !

Yes!:smile: Thank you! //Martin

8. ### Sequences - factorial r, !

Can anybody help me solving this? Write in terms of factorials n((n^2)-1) The correct answer is (n+1)!/(n-2)! but I don't know how to get there, and since it's week- end I have no chance to ask anyone teachers, etc. //Martin
9. ### Quantizing speeds with the cosmological constant

When Cosmological constant was large. Another interesting affect of Livine's new paper is the effects quantizised speed has when Cosm. const. is big (as it were in the early phases of big bang). His paper proclaims that speed then only could have a few certain values, something that has a great...
