could einsteins theroy of special relativity be put into practice with regards to time travel into the future? i have run and rerun this theory and can only get to the same conclusion - if time travel is possible then it is only possible to go back in time and not forwards in time.

In order for human race to live on other planets we first have to get there.But how with what technology?

If the universe has no start and no ending and is always moving outwards the longer we take to get to other planets is getting more difficult as we speak what technology would we need to get there we would need a major advancement in future engines to take us to the speed of light in order to reach these planets in our lifetime and what would happen if we did reach the speed of light maybe Dr Hawking can answer this do we send out motherships with breeding couples so the children can reach a planet that we could live on i agree with Dr Hawking our planet is on time limit and i think we do need to get out there and explore new planets to live on.

What's the trick of solving collisions with friction?

A block of mass m lying on a rough horizontal surface is given an initial velocity of vo. After traveling a distance d, it makes a head-on collision with a block of mass 2m. How far does the second block move before coming to rest?( Assume that the coefficient of friction, uk, is the same for both blocks).

I use V2=Vo2 +2ax for m2 but keep getting half the right answer.

answer: 2Vo2 -4d
9ug 9
What am I doing wrong... how do you solve this one.

What's your personal vote on the Pluto issue? Why?

Pluto's planethood is in question and the IAU will give the final word on its status next month. One thing is certain, we won't have the same number of planets in our solar system. If Pluto is demoted to the Kuiper belt, we'll have 8. If it maintains its status, bigger 2003 UB313 will likewise be considered a planet, making it 10. What are your views?
