If You Were Given 10 Trillion Dollars, A Team Of The World’s Best Scientists And The Use Of Any Scientific Facility Or Facilities In The World And You Were Told To Solve One Scientific Problem What Would It Be?

There are a few well known ‘hard problems’.

1. The unnecessary senescence of cells
2. A battery with the energy density of gasoline.
3. The constitution of dark matter (the missing ‘charges’)
4. General Artificial Intelligence.

I suspect that we will solve them in reverse order.
All of the problems are seemingly solvable – just very expensive.
