A study by the University of California San Diego has claimed that by 2050, the Sun is expected to become cool. You might think “what’s the big deal,” but remember that this means the solar activities that create the heat of the Sun to sustain life on Earth may diminish. And the last time it happened was in the 17th century when the Thames River froze. Scientists call this the “Maunder Minimum”.
Physicist Dan Lubin at the university and his team studied the past event and concluded that we are in for a worse case. The Sun is expected to get much dimmer than last time and, in scientific terms, it is a “grand minimum” — a time period in the 11-year solar cycle when the solar activities are at the lowest point.
