I don't think that is the right way to think about it, it has more to do with trajectory bending. For example, let's say an object is going radially outwards away from the sun at 10 km/s when it encounters a planet that is or

Deepfakes are implemented with Generative Adverserial Networks (GANs), where one component is a discriminative network that is already trying to distinguish real from fake, to provide feedback to the generation. So I think any detection alg

On the other hand, if the virus spreads so fast that we can't keep up with burying the dead, then that might also cause social unrest, to put it mildly. In Ecuador, families have had to keep their dead for over a week while waiting for
