Title: Cheap Astronomy – Dear CA #74: The Big Questions

Organization: Cheap Astronomy



Cheap Astronomy answers the Big Questions.

Dear Cheap Astronomy – How long did the Universe take to complete the periodic table? 

So, this is really a question about nucleosynthesis, which began with the Big Bang and continues today in stars – and on a small scale in human-built laboratories.

Dear Cheap Astronomy – Is Interstellar travel really out of the question? 

Our current understanding of physics suggests that traveling to the nearest star within a human life time is pretty much out of the question. Regardless of what type of engine you use – even approaching, let alone passing the speed of light puts you at risk of destroying your spaceship through collisions with just specks of cosmic dust.
