Thinned array curse

The Thinned Array Curse is a problem with computer simulations of the universe. When scientists use computers to simulate the universe, they need to use a lot of data points, called an array, in order to make their simulations as accurate as possible. However, if they use too many data points, the simulations take too long and too much energy to run. To get around this, scientists sometimes thin out the array, which means they take some of the data points away, so the simulation runs faster and uses less energy. Unfortunately, thinning out the array can also cause inaccuracy in the simulation, because by taking away data points, it’s like looking at the universe with less detail. This is the Thinned Array Curse – thinning the array can make the simulation run faster, but it also makes it less accurate.
