This website is made by me, Subhadeep Sarkar, for Personal Project in Year 11 in Dubai International Academy (DIA).

The majority of the information and images are my own, but these are a few sources which were especially useful during my research.

Inside Black Holes
This is an awesome website made by Andrew Hamilton, explaining various phenomena inside and around black holes. Many confusing concepts are explained well here.

Falling Into a Black Hole
This website is also made by Andrew Hamilton, but it goes more into detail about physics around or near a black hole.

Carter-Penrose diagram and black holes
This PDF contains more information on penrose diagrams and their mathematics.

Cornell Astronomy
These pages contain really nice diagrams nad information about astronomy in general.

"Travel INSIDE a Black Hole" by Vsauce
A YouTube video which first got me interested in black holes. This channel has many amazing educational videos.

"What Happens at the Event Horizon?" by PBS Space Time
Another amazing YouTube channel. This specific video cleared up many misconceptions and explained the penrose diagrams really well.
