anyway tantum, about the hydrogen in stars, sol burns 2,000,000 tons of hydrogen every second. i forgot how much it was exaclty, heard it from that sunkis comercial. the sun's gravity forces the hydrogen to fuse together, causing nuclear fire. nuclear fire fights against gravity by keeping the star from collasping on itself. when it runs out it will fuse whatever other element it has before dying. scientist say that 5,000,000,000 from now, the sun will bollon into a red gaint, swallow mercuary and venus, and cook earth' surface to 2,500 degrees.
closes nebula is....................horsehead nebula?
