How do i become a physicist or an astrophyscist

[yuganes warman]

Hey there. I am deciding to pursue my studies to physics or astrophysics course. The problem is i like space and really wanted to do researches on some of the impossibilities such as time traveling or space warping and black hole theories. What should i do and how many years will it take me in the long run ?
