nuclear fusion

BH* objects are not true stars because they lack nuclear fusion in their centers.

Throughout its life, a star keeps a stable spherical shape because gravity pulls inward while pressure from nuclear fusion pushes outward.

In documents released afterwards the areas for investment also included defence, drugs, critical minerals, aerospace and space, cyber security, quantum computing and nuclear fusion.

While nuclear fusion might solve energy-grid problems in the distant future, it could take decades to play out based on practical and recent history.

In the longer term, Google is looking toward nuclear fusion as opposed to fission: While the latter is used currently in power plants, the former can provide much more energy in a potentially safer process.
