The Sun gets lighter by 4 million tons (4×109 kg) every second. Using Einstein's famous equation --- E=mc2 --- figure out how much energy is released by the Sun every second (called the solar luminosity). Now let's make a comparison. Through a chemical reaction, one kilogram of the explosive TNT (dynamite) releases 4.2 million joules. How many TNT you need to provide the same amount of energy every second?

1) 4.25×10^15 kg

2) 8.57×10^19 kg

3) 4.25×10^9 kg

4) 8.57×10^12 kg
