That's what most physicists thought, in the early 20th century, until they became aware of the implications of quantum mechanics... Are you familiar with the Uncertainty Principle? • https://en.m.wikipedia.org/wiki/Uncertainty_principle https://en.m.wikipedia.org/wiki/Uncertainty_principle In short, it's fundamentally impossible to completely and precisely describe the current state (position & velocity) of any particle. The more precisely you measure one of those values, the more uncertain the other becomes, in proportion. This is a fundamental physical reality of the universe... It's not just an imperfection of how we take measurements. At a quantum level, the universe is actually random in it's behavior. You can make statistical predictions, which in larger & larger quantity can asymptotically approach certainty, under the right conditions... But at a macroscopic level, outcomes will always reflect some amount of randomness. By implication, you cannot fully predict the future behavior of a system by knowledge of its current state. This was a tremendous shock to the worldview of many scientists, including Albert Einstein. But over the last century, every attempt to disprove the reality of this fundamental randomness has failed.
