To do that, go to the Network Tab and select the Connectivity sub tab. Then run the âConfigure a Virtual Private Networkâ wizard from the task pane on the right. Select âAllow users to connect to the server by using a VPNâ and the VPN wizard will run.
Measuring the strength of the polarisation due to gravitational waves gives us a ballpark figure of the amount of energy involved at the time of inflation and helps pin down when inflation occurred. *Not to be confused with a gravity wave (which is a wave driven by the force of gravity).
The waves are then very weak by the time they reach Earth. This makes gravitational waves hard to detect. How do we know that gravitational waves exist? In 2015, scientists detected gravitational waves for the very first time. They used a very sensitive instrument called LIGO (Laser Interferometer Gravitational-Wave Observatory). These first gravitational waves happened when two black holes crashed into one another.
