Astronomy 309 Gebhardt Homework 2 1. The idea that the Large Hadron Collider will cause a massive black hole is absurd for many reasons. For one, there are similar collisions in our earths atmosphere all the time, so if there would be a black hole it would have already happened. Another reason is because it is almost impossible because the odds are so small that they are negligible. 2. If the size is less than 5 suns than the white dwarf can take pressure because of degenerate electrons. A neutron star happens because there is enough force to force electrons and protons together into neutrons. 3. It is the center of a black hole where matter is crushed into infinite density, gravity, and causes an

R: Schwarzchild Radius SM: Solar Mass (kg/kg) Earth Earth->Solar Mass = 1/109 R = 3 km * 1/109 SM (kg/kg) R = 3/109 km Universe R = 3 km * 1*10^22 SM (kg/kg) R = 3*10^22 km 5. Earth V = 4/3*(3.14)*((3/109km)^3) = 87287.6 m^3 M = 5.9736×10^24 kg D = M/V D = 6.84*10^19 kg/m^3 Universe V = 4/3*(3.14)*((3*10^22km)^3 = 1.1304*10^77 m^3 M = 1.9891*10^52kg D = M/V D = 1.7596426*10^-25 kg/m^3 Air = 1.2 kg/m^3 The Earth's black hole density would be a lot more than air while the universe's black hole density would be a lot less....
