What is Virtual Reality and what we can use it for

 Virtual Reality (shortly VR) is a computer simulation that requires VR Goggles and sometimes two controllers that act as our hands. Virtual Reality can be used to many things like showing people how it may have looked like being a victim of the eruption of mt. Vezuvius in 79 CE by creating a realistic simulation. VR can also sometimes change perspectives of people on other countries by showing them people in poverty that need our help.  Over the years the industry for VR equipment and games has rose a lot but it very expensive and still in it's early times where there's still a lot of room for improvement. In the future Virtual Reality is said to play a big role in our lives, for example people will have distance meetings in it, use it for visualisations of a house that they are planning to build and it may even replace out TVs.
