"Yes, Really," Bruce Teased Back. He Sped Along To The Next Stoplight Just As Iron Man Hurtled Through

"Yes, really," Bruce teased back. He sped along to the next stoplight just as Iron Man hurtled through the intersection. Bruce sighed and pressed his fingers into his temples.

"Should we just ignore it, or do you want to join them?" he asked, as Captain America sprinted past them after Iron Man.

"Are you sure this is legal?"

"If not I know a couple of brilliant lawyers that would be more than willing to help us out." Andie shrugged, looking over at him. "Don’t worry so much."

Bruce laughed and clapped her on the shoulder before he buckled himself in and started up the car. They peeled away from the building and he sped away until they settled into the comfortable normalcy of highway traffic on their way back into the city. "What's the file say, anyways? What're we doing here?"

"Are you sure this is legal?"

"If not I know a couple of brilliant lawyers that would be more than willing to help us out." Andie shrugged, looking over at him. "Don’t worry so much."

Bruce laughed and took the file from her. "Will do, boss." He gave her a joking salute before sliding out of the car. He was gone for about ten minutes before he jogged back to the car and hopped back in. He grinned at Andie, the monitor strapped to his wrist beeping with his heightened pulse.

"Are you sure this is legal?"

"If not I know a couple of brilliant lawyers that would be more than willing to help us out." Andie shrugged, looking over at him. "Don’t worry so much."

Hulk smiled and grunted. Happy Lady was pleased with Hulk. Hulk made Happy Lady happy again. Hulk smashed two more witch, and- Metal-man. Metal-man here, and Flag-man, here to help Hulk smash witches. Hulk roared in delight. Hulk smashed another witch and roared at one that tried to get near Happy Lady. Banner tried to talk to Hulk, but Hulk ignored Banner. Banner stayed in the back.

"Are you sure this is legal?"

"If not I know a couple of brilliant lawyers that would be more than willing to help us out." Andie shrugged, looking over at him. "Don’t worry so much."

We May All Be Made of Stardust, But What Makes Stardust? Most of my followers should know that the atoms that comprise your body and just about everything around you were forged in stars. If you didn’t know this I urge you to spend more time avidly watching Cosmos. But how does this process actually occur? The secret lies in nuclear fusion which is essentially the opposite to fission (which causes radioactive decay). Fusion is simply the combination of two nuclei into one larger nuclei. In the process a large amount of energy is released. The energy that is released is what powers stars and gives you sunlight.  The cornerstone of this process lies in a property called binding energy, which is essentially the energy that holds together an atom’s nucleus. The important thing is to relate this to the mass of nucleus by referring to it as "binding energy per nucleon" (protons and neutrons essentially). Of all the elements iron has the highest binding energy per nucleon which means that combining atoms smaller than iron releases energy, whilst combining atoms that are larger requires an energy input. Heavier elements than iron are typically only produced during supernovas (a remnant of which is pictured above) which also have the effect of distributing the atoms in shells or jets.
