thanks, all, useful and interesting information.

so...after thinking that stars burn most if not all of their hydrogen over that 10 billion year period, I am actually right in calculating that the sun will only burn 7% of its hydrogen? many MANY thanks to both merryjman and mgb_phys for putting me back on the right track, and possibly...

merryjman: youve got me thinking now :D (or :(( I am not sure) i reread my question, and it told me to assume hydrogen->helium is the only nuclear reaction occurring in the sun. there is another reaction which involved helium, beryllium, boron and back to helium, and there is also the CNO...

the distance is 1,000,000 light years. light travels at 3x10^8 m/s (300,000,000 m/s). therefore at 300,000,000 m/s it will take 1,000,000 years to reach your destination. to get there quicker, you would need to travel faster. let's say you wanted to get there in 10 years, not 1 million years...

hey guys, I am new here and thought you might like to help me out. I am a first year astronomy student at Curtin University in Western Australia. my current assignment has asked me to calculate the mass of hydrogen converted in the sun to helium and energy over 10 billion years (10 billion...
