[00:00:00]Right now, this exact second, >> [music] >> the sun is losing 4 million tons of mass.

[00:00:04]In its core, hydrogen atoms are slamming together to form helium.

[00:00:08]>> [music] >> Four hydrogens go in, one helium comes out. But the helium weighs slightly less than the four hydrogens did. That missing mass becomes pure energy. E = mc squared in action.

[00:00:19]>> [music] >> The sun does this fast enough that every second, 4 million tons of its mass >> [music] >> become the light and heat that warms Earth. It's done this for 4.6 billion years and will keep going for another 5 billion.

[00:00:32]We're fine. Comment the science topic you want next. [music] Black holes, time travel, or quantum.
