Blair: Hey guys, have u heard about VR?
Dale: Virtual reality? Sure.
Tiffany: What's VR?
Blair: VR stands for virtual reality. It's used in many fields. For example games.
Dale: Knew you'd mention games first ;) 
Tiffany: So, except games, where can it be used?
Dale: There are really numerous applications! For example, designing a building. U can do the maths, draw the lines and finally see the product or show it to your client!
Blair: Or in medicine! For example, the doctors scan the faulty organ and then make w VR projection and decide what the best treatment or surgery is.
Tiffany: Or for example, medicine students can learn by performing surgeries in virtual reality?
Blair: Absolutely!
Dale: The possibilities are countless! I've even heard it can be used for weather forecasting. Don't know how, though.
Blair: And I've just read you will be able to fly to the moon with VR!
Tiffany: Can't you do that now? Like in a game or something?
Dale: SpaceX?
Blair: Exactly!
Tiffany: What's SpaceX?
Dale: A company set up by Elon Musk.
