We could be entangled with someone from the past, or the future, and not be aware of it consciously? Weird.
But now, a new experiment has scientists believing that quantum entanglement doesn’t just apply to spatial gaps, but time itself.
Einstein famously battled with physicist Niel Bohr over the predictions and theories of quantum mechanics, such as the wave function. He also corresponded with Erwin Schrödinger—yes, of Schrödinger’s cat—and in one of his 1935 letters, Einstein stated: “I know of course how the hocus pocus works mathematically. But I do not like such a theory.”
The principle of entanglement held that it was impossible to independently describe two quantum systems that had once been united. One influenced the other instantaneously across vast distances, which meant that in some cases it appeared as though information was being transmitted and received faster than the speed of light, which Einstein believed was impossible.
This is the shocking suggestion by a team of physicists at the Hebrew University of Jerusalem, who believe they have used “entanglement swapping” techniques to show that quantum nonlocality also includes temporal nonlocality.
In other words, quantum systems can communicate instantly with one another not only over vast distances of space but vast distances of time.
The experiment involved measuring the polarization of pairs of photons and tracking their entangled relations.
The results showed “temporally nonlocal” correlations between particles. In other words, particles that never existed contemporaneously in space can still share an entangled bond over time. This suggests the possibility of a much more vast and deeper quantum connective tissue to the universe that transcends space-time.
The implications of this are stunning. As ScienceAlert noted:
“Prima facie, it seems as troubling as saying that the polarity of starlight in the far-distant past – say, greater than twice Earth’s lifetime – nevertheless influenced the polarity of starlight falling through your amateur telescope this winter.
Even more bizarrely: maybe it implies that the measurements carried out by your eye upon starlight falling through your telescope this winter somehow dictated the polarity of photons more than 9 billion years old.”
The anomalies of quantum physics troubled Einstein until the day he died. It seems now we’re getting even greater detail on why he was so disturbed by what scientists saw as they pulled back the curtain on the nature of existence.
The results of these experiments pose vexing questions that tear at the very fabric of reality: Could it be that our observations in the present are influencing events from the distant past, such as the Big Bang itself, and vice versa?
