The Second Avatar movie passed $2 billion in box office this weekend. The movie will likely pass Titanic for third highest box office. This will only be behind the first Avatar and Avengers Endgame. The movie has been out for seven weeks and made about $100 million is its seventh week with a 40% drop from the prior week.

The start of the first Avatar movie showed the Valkyrie Antimatter rocket design. This was an actual antimatter rocket design. The first Avatar movie made almost $3 billion in box office. The second movie should be able to reach $2.3 to 2.5 billion and could go higher as the first movie had exceptional late-release earnings. James Cameron's biggest hits just keep rolling with repeat viewings of Titanic and Avatar.

A startup did try to generate antimatter to catalyze fusion reactions. However, Positron Dynamics business failed, despite solid science and technology. Positron Dynamics was trying to use Krypton isotopes to generate positrons. They wanted to breed more Krypton isotopes. They sidestep the issue of antimatter storage, which is one of the biggest problems. We can make tiny amounts antimatter but cannot store what we make for any long amount of time. It would take 10 school buses of volume at the Brillouin limit to trap 1 microgram. They were slowing the positrons that are generated. Krypton 79 isotope generates hot positrons. They were using a system to moderate (slow) the positrons so they can be used.
