There is Lisa Randall (eg Are there extra dimensions?), Nima Arkani-Hamed (eg Why is Quantum Gravity so Significant?), Juan Maldacena (eg Why Black Holes are astonishing), Lee Smolin (eg What do Black Holes and Dark Matter reveal?), Roger Penrose (eg Is Mathematics Invented or Discovered?), Fotini Markopoulou (eg What is a Theory of Everything?), Paul Davies (eg Do Science and Religon conflict?), and many more... Enjoy!
