Yes, theoretical astrophysics is a branch of astrophysics.
I am most interested in, Theoretical Astrophysics.
Cosmology
Yes, Stephen Hawking is a scientist, specializing in theoretical astrophysics and cosmology.
A picture of a white hole in astrophysics is significant because it represents a theoretical concept that is the opposite of a black hole. While black holes pull in matter and light, white holes are thought to expel matter and light. However, white holes have not been observed in nature and remain a theoretical concept in astrophysics.
Astrophysics deals with physics of the universe, and is considered a branch of astronomy, but with more specific emphasis on physics, laws and properties of the cosmos.
No. There is a separate branch called astrobiology, where knowledge of biology may be helpful.
Science can be broken down as either practical (or physical) and theoretical. Any of the purely theoretical sciences are difficult to quantify as to their complexity although theoretical astrophysics with their work with string theory and n-dimensional interactions would rank as being very obtuse from the layman's point of view.
Theoretical Chemistry is the branch of chemistry that studies chemical behaviors and principles using math and computers.
<p>Astronomy or Astrophysics depending on which objects... large or small.<p>
John Richard Bond is an astronomer and a member of the Canadian Institute for Advanced Research and helped establish the Canadian Institute for Theoretical Astrophysics.
Theoretic probability is a branch of mathematics: it is not a profession.
