With this week鈥檚 fireworks fresh in mind, we鈥檙e allowed to wonder: What is the universe鈥檚 most awesome energy? 

Right now, when early summer solar power is so strong, we might first say that 鈥淭he Sun鈥 is the most powerful force. Not a bad starting point.

The Energy of our Sun

We鈥檙e talking nuclear fusion, first revealed in 1920. Turns out, at a high enough temperature, four ordinary hydrogen atoms fuse into one of helium. This always releases energy. The Sun鈥檚 core emits 96 billion megatons each second. Essentially 96 billion H-bombs exploding continuously.

This conversion of mass to energy reduces the Sun鈥檚 actual weight by four million tons per second. Sounds worrisome, but it merely adds up to losing one Earth-mass since it was born.

The Explosions of Supernovas

A few blue, super-hot summer stars one-up the sun by releasing the energy of 100,000 suns. We call them stars, but they鈥檙e really nonstop explosions. 

Yet they鈥檙e popguns compared to supernovas鈥攚hich are exploding stars. A supernova is the largest explosion that takes place in space鈥攁s space bright as a half billion Suns. Read more in my article about supernovas.

The Power of Antimatter

But let鈥檚 not stop there. Say we want even greater power. Then we鈥檝e got to make matter collide with antimatter. This actually happens in our own Milky Way galaxy. It鈥檚 the 100% conversion of matter to energy.

A single gram of salami, fully converted into its innate energy, could power a 100-watt bulb for 30,000 years. A dollar bill weighs one gram. So squeezing the energy from a single paper currency note could run a 1 HP motor for 1,500 years. Einstein was right: Converting any object鈥檚 mass to energy yields frighteningly awesome power.

Zero-Point Energy

Yet there鈥檚 even an energy greater than when antimatter meets normal matter. It鈥檚 the unseen power that fills all of space. Called vacuum energy, or Zero Point energy, it鈥檚 so powerful, an empty mayonnaise jar of vacant space might be able to boil away all our oceans in three seconds.

So yes, we have learned how to make ever-bigger fireworks. But they鈥檙e cap pistols compared to what the universe has hidden in each bit of its seeming emptiness.
