    Graduate Big Crunch may create time-reversal?

    Nothing with a mass can travel faster than the speed of light so Travelling faster than the speed of light and having mass is impossible. one of the main side effects of going that fast is actually having an increased mass, and slowed time. Please correct me if I'm wrong :)

    Graduate How Do Spiral Galaxies Maintain Their Shape?

    Yeah that star with the spiral arms is very interesting, i would like to see more pictures of it :S

    High School What Causes Sunspots and How Do They Affect Solar Brightness?

    They are caused by magnetic activity in which the specific area cooler than the area around it, showing a difference in colour. Usually 1000 degrees celsius difference.

    Impossible, Time can't go backwards only slowed or forwards.

    Physics What Career Paths Await an Aspiring Astrophysicist After University?

    Thanks guys, really reinforced my willingness to become a astrophysicist. In new south wales i need 75 percent on my HSC (higher school certificate) to do science in university and 80 to do it in Sydney University (i really want to go there, it's amazing, edwardian architecture for one of the...

    Undergrad Singularity in Astrophysics: Meaning & Etymology

    Quite Basicaly Mhozdag, "a location where gravity is so mad that space and time become indistinguishable" is a very good explanation on how a singulairty behaves (ones in black holes or the big bang)

    Physics What Career Paths Await an Aspiring Astrophysicist After University?

    Thanks Iby, I'm in australia, and yes 'middle' or High school as we call it in australia, I'm a year 10 doing phys,chem and bio. But i panicked when i found out the max salary for astrophysicists is 150K WITH a Ph.D. I've wanted to do it since i was 5, my father bought me a science book...

    Graduate Amount of nuclear power need to propel a shuttle at the speed of light

    Dw, sounded a bit hazy at first, traveling backwards is impossible.

    Graduate Amount of nuclear power need to propel a shuttle at the speed of light

    @ Cosmo Novice, this is from a Stephen Hawking Documentary actually, pretty cool, it's about time travel. Strongly recommend some really interesting facts on it.

    Graduate Amount of nuclear power need to propel a shuttle at the speed of light

    Sorry to spoil but traveling at the speed of light is impossible. The universe does everything to prevent you from traveling as fast. Increasing mass, reducing time and another which i sadly can't recall atm. Interesting fact: I have done some research on this and moving at 99.9999999% of the...

    Undergrad Singularity in Astrophysics: Meaning & Etymology

    In space a singularity is something that's concentrated to a point. common examples are that of the big bang and black holes.

    Undergrad Birth of a Planet: The Formation & Heavy Elements

    Yes, it is believed that the all elements heavier than helium and hydrogen are remnants of supernovae. The most plausible cause in my opinion would be planetary nebula.
