There\u2019s a lot of discussion about \u201ctime\u201d in the world of quantum physics. At the micro level, where waves and particles can behave the same, time tends to be much more malleable than it is in our observable realm of classical physics.<\/p>\n

Think about the clock on the wall. You can push the hands backwards, but that doesn\u2019t cause time itself to rewind. Time marches on.<\/p>\n

But things are much simpler<\/em> in the quantum realm. If we can mathematically express particulate activity in one direction, <\/i>then we can mathematically express it in a diametric one. <\/span><\/p>\n

In other words: time travel actually makes sense through a quantum lens. Whatever goes forward must be able to go backward. <\/span><\/p>\n

But it all falls apart when we get back to classical physics. I don\u2019t care how much math you do, you can\u2019t unbreak a bottle, untell a secret, or unshoot a gun. <\/span><\/p>\n

As Gid\u2019on Lev points out in a recent article<\/a> on Haaretz, this disparity between quantum and classical physics is one of the field\u2019s biggest challenges. <\/span><\/p>\n

Per Lev\u2019s article:<\/span><\/p>\n

\n

Hawking demonstrated that regarding black holes, one of the two major theories leads to an error.<\/span><\/p>\n

According to his calculations, the radiation emitted by the hole is not a function of the material the hole swallows, and therefore, two black holes that formed by different processes will emit the same exact radiation. This meant that the information on every physical particle swallowed into the black hole, including its mass, speed of movement, etc., disappears from the universe.<\/span><\/p>\n

But under the theory of quantum mechanics, such deletion is impossible.<\/span><\/p>\n<\/blockquote>\n

Hawking was wrong, then he was right<\/h2>\n

Lev\u2019s article goes on to explain how Stephen Hawking eventually conceded (he lost a bet<\/a>) that the information entering a black hole wasn\u2019t gone. He, of course, couldn\u2019t explain exactly <\/span>where<\/i> it went. But most physicists were pretty sure it had to go somewhere \u2013 nothing else in the universe just <\/span>vanishes.<\/i><\/p>\n

Fast forward to 2019 and two separate research teams (working independently of each other) published<\/a>pre-print papers<\/a> seemingly confirming Hawking\u2019s hunch about the persistence of information.<\/span><\/p>\n

Not only were the papers published within 24 hours of each other, but the lead authors on each ended up sharing the 2021 New Horizons Breakthrough Prize for Fundamental Physics<\/a>.<\/span><\/p>\n

What both teams discovered was that a slight change in perspective made all the math line up.<\/span><\/p>\n

When information enters a black hole it <\/span>appears<\/i> to be lost because, for all intents and purposes, it\u2019s no longer available to the universe.<\/span><\/p>\n

And that\u2019s what stumped Hawking. Imagine a single photon of light getting caught in a black hole and swallowed up. Hawking and his colleagues knew the photon (and the information that was swallowed up with it) couldn\u2019t be <\/span>deleted<\/i>. <\/span><\/p>\n

But, according to Hawking, black holes leak thermal radiation. And that means they eventually lose their energy and mass and\u2026 fade away. <\/span><\/p>\n

Hawking and company couldn\u2019t figure out how to reconcile the fact that once a black hole is gone, anything that\u2019s ever been inside it appears to be gone too. <\/span><\/p>\n

That\u2019s because they were looking in the wrong places. Hawking and others were trying to find signs of <\/span>the missing information leaking out simiarly along a black hole\u2019s event horizon<\/em>.<\/span><\/p>\n

Unfortunately, using the event horizon as a starting point never panned out \u2013 the numbers didn\u2019t quite add up.<\/span><\/p>\n

The 2021 New Horizons Prize winners figured out a different way to measure the \u201carea\u201d of a black hole. And, by applying the new lens to measurements over various stages of a black hole\u2019s life, they were finally able to make the numbers add up.<\/span><\/p>\n

Here\u2019s how this relates to time travel<\/span><\/h2>\n

If these two teams did in fact demonstrate that <\/span>even a black hole<\/i> can\u2019t render information irreversible, then there might be nothing physically<\/em> stopping us from time travel.<\/span><\/p>\n

And I\u2019m not talking about that hard-to-explain, gravity at the edge of a black hole, your friends would get older while you stayed young kind of time travel.<\/span><\/p>\n

I\u2019m talking about real-life Marty Mcfly time travel where you could set the dials in the DeLorean for 13 March 1986 so you could go back and invest in Microsoft on the day its stock went public.<\/span><\/p>\n

Now, much like Stephen Hawking, I don\u2019t have any math or engineering solutions to the problem at hand. I\u2019ve just got this physics theory.<\/span><\/p>\n

If information can and does<\/em> escape from black holes, then it\u2019s only logical to assume that other processes which we only see in quantum mechanics could also be explained through classical physics. <\/span><\/p>\n

We know that time travel <\/span>is <\/i>possible in quantum mechanics. Google demonstrated this by building time crystals<\/a>, and numerous quantum computing paradigms rely on a form of prediction that surfaces answers using what\u2019s basically molecular time-travel<\/a>.<\/span><\/p>\n

But we all know that, when it comes to quantum stuff, we\u2019re talking about particles demonstrating counter-intuitive behavior. That\u2019s not the same thing as pushing a button and making a car from the 1980s appear back in the old Wild West<\/a>.<\/span><\/p>\n

However, that doesn\u2019t mean quantum time travel isn\u2019t just as mind-blowing. Translating time crystals into something analogous in classical physics would mean creating donuts that reappear on your plate after you eat them or beer that reappears in your glass no matter how many times you chug it.<\/span><\/p>\n

If we concede that time crystals exist and information <\/span>can<\/i> escape a black hole, then we have to admit that donuts \u2013 or anything, even people \u2013 could one day travel through time too. <\/span><\/p>\n

Then again, nobody showed up for Hawking\u2019s party<\/a>. So, either it isn\u2019t possible or time travelers are jerks. <\/span><\/p>\n
