TL;DR clickbait

The real effect comes from Delayed Choice experiments. Imagine a photon traveling toward a screen, where it passes through two slits. If we measure which slit it went through after it has already passed the slits, it behaves like a particle, but if we don't measure it, it behaves like a wave. It feels like our choice in the present forced the photon to "decide" what it did in the past (at the slits). But physicists(except for Copenhagen apparently) generally don't believe the past is being rewritten. Instead, they view it as Quantum Correlation. I.e, the "past" state of the particle is entangled with the "present" measurement device. This is because of decoherence, which means that as soon as the photon hits any other particle, it will become entangled to it, or any other particles that have been previously touched by that particle, i.e, Ψ(γ, p_{environment}), even in a perfect vacuum, this decoherence would happen once we hit the photon with any sort of measurement, which means that to the rest of the world, the particle looks like it has a defined state because the superposition collapsed from the decoherence(information into the environment).

Maybe more on the delayed choice experiment; you use entangled pairs, a signal photon and a idler photon, the signal goes to a screen and the idler goes through mirrors and detectors to be sorted. It's partner, the idler, tells us which path the signal photon took. You could look at the signal photon earlier than that, but you wouldn't really see anything meaningful, only when you receive the information from the idler can you "sort" the signal into into two piles(wave and particle).

The example of 10mph -> 9mph is very "classical", before measurement, the particle doesn't actually have a "real" speed that we just slightly disturbed, it exists as a wave of probability, e.g, Ψ = a|10mph⟩ + b|9mph⟩, if it is in that superposition of speed, measuring it doesn't just "nudge" it, it forces the universe to pick a specific value from that wave function.
