As far as we can tell from modern science, there's no upper limit to temperature. There sure is a lower limit, though. We call that absolute zero, measured as -273.15 °C (-459.67 °F). Scientists have ...

The LIGO gravitational wave observatory in the United States is so sensitive to vibrations it can detect the tiny ripples in space-time called gravitational waves. These waves are caused by colliding ...
