Stephen Hawking's interment service is scheduled to take place at Westminster Abbey, Broad Sanctuary, London, on Friday June 15 at 12 PM. Members of the public who wish to attend may use here; there are 1,000 open spots and attendees will exist randomly selected. Only those who apply may notice an oddity. When asked for date of birth, the nautical chart runs to 2038. This is non a typo.

Stephen Hawking believed that time travel to the by was theoretically possible (you can read a lecture of his on the topic here, in language that's quite outgoing, even for the layman). The author even went so far as to throw a party for time travelers in 2009 to see if whatever might go far. (None did). There are a diverseness of theories on why this might exist and then, over and above the obvious "Time travel to the past isn't possible," including the thought that time travel to the by is possible, but that it cannot exist used to travel to a point before time travel to the past was possible.

In this theory, if time travel was somehow miraculously invented in 2022, you'd be able to utilise it to visit the by of 2022 in 2070 — but nothing could take you to a point before. Time travel to the future, in contrast, is known to exist theoretically possible, provided you lot observe a fashion to reach the relativistic speeds required. A better manner to frame the trouble is to say that we know, based on our electric current understanding of the laws of physics, that the laws of physics permit for travel to the time to come, while all theories of how one might travel to the past are much more vague.

A spokesperson for the Stephen Hawking Foundation said, "Nosotros cannot exclude the possibility of fourth dimension travel every bit it has not been disproven to our satisfaction. All things are possible until proven otherwise. But so far we have had applications from all round the world, and we practise hateful round — there are no flat-Earthers hither."

The chance of fourth dimension travelers showing up at Hawking's funeral are low, and the run a risk of them revealing themselves, one might presume, are even lower. In nigh all scientific discipline fiction, time travel is shown in just a handful of means:

  • One person/group is attempting to change the timeline, while another person/grouping acts to prevent this. (Terminator, Star Trek: First Contact)
  • A person/grouping attempts to remove an object from the timeline without changing history. This bones plot tin can also be used to remove information that was known in the past, but lost in the time to come, without the difficulty of transporting whales at warp speed within a Klingon Bird of Prey.(Star Trek 4: The Voyage Home)
  • A person/group attempts to change the timeline to avert catastrophe. (X-Men: Days of Future By)

In near of these cases, characters avert telling anyone they're time travelers to the maximum extent possible. Only Hawking manifestly didn't detect this particularly persuasive, noting in the lecture above that "even if there were sound reasons for keeping us in ignorance, human nature existence what it is, it is difficult to believe that someone wouldn't show off, and tell us poor benighted peasants, the secret of time travel."

My Own Theory

I've had a theory on this topic for years but never had a chance to share it. Permit me say up forepart that I'm sharing this in jest, rather than as a serious scientific concept. In fact, my understanding is that near physicists don't believe time travel of the sort I'm going to depict is possible in the first identify. But just for the fun of it, here it is.

Report history long enough, and you'll discover there are some incredible coincidences in our timeline. Stanislav Petrov, the Soviet officer who disobeyed straight orders and his own training by refusing to study that the United States had launched nuclear missiles at the Soviet Union back in 1983, wasn't even supposed to be on duty that night. Petrov was not a combat-hardened soldier, just an engineer. He troubleshot computer hardware for a living. When his board lit up with signals that indicated an American launch, he cleared the error. And then, incredibly, he cleared it once more when new launch signals appeared from multiple locations in Northward America. Petrov may take single-handedly prevented nuclear war. Soviet doctrine of the day taught that computers were infallible and were to be trusted in all circumstances; far from being rewarded, Petrov was reprimanded.

Everyone knows that the assassination of Archduke Franz Ferdinand kicked off Earth War I. Less well-known is the fact that the first ii bomb-throwers refused to act and the third scored an indirect hitting. Ferdinand survived. Subsequently completing a serial of remarks the Boondocks Hall of Sarajevo, Ferdinand decided to modify his schedule and visit the wounded survivors of the before flop attempt. The driver was to follow the Appel Quay to the Sarajevo Hospital, but was not informed of this. As a result, he turned off Appel Quay on to Franz Josef street, following the plan for Ferdinand'due south original visit, which took them past Schiller's delicatessen where Gavrilo Princip was waiting. Ferdinand'due south driver was notified of the direction change near the delicatessen and stopped the car to reverse information technology virtually direct in forepart of Princip's position. Princip fired from five feet abroad. World War I was the result.

And while the "evidence" for this concluding one is a bit weaker, I'm a longtime Titanic buff who can't resist tossing it in. Why did the Titanic sink? Information technology striking an iceberg. But information technology might not have sunk in the first identify, had seaman David Blair non walked off with the primal to the storage locker where the lookout'southward binoculars were kept. (The relative impact of this is disputed, just Lookout Frederick Fleet, who first spotted the iceberg with the Mark I Eyeball, believed information technology would have fabricated the difference). Alternately, the ship might've survived if Start Officeholder Lightoller had hitting the iceberg caput-on rather than attempting to pass it. And, of class, the passengers might've been saved if the SS Californian hadn't ignored its emergency rockets. But the sinking of Titanic had an enormous impact on ship designs, lifeboat regulations, and pop culture. The sinking of Titanic didn't invent the phrase "women and children kickoff," but it popularized and embedded it in public consciousness.

The Titanic raises steam and heads into history. This is the final known photo of the vessel.

And equally a point of reference, don't fifty-fifty go me started on "The Wreck of the Titan: Or, Futility" an 1898 novella about a fictional luxurious bounding main liner, the Titan, an 800-pes ocean liner (Titanic: 882 feet, 9 inches) with a maximum speed of 25 knots (Titanic: 22.5 knots), with a displacement of 45,000 tons (Titanic: 46,000 tons), designed as a triple-spiral steamer without plenty life boats, described equally "unsinkable," and which sinks in the North Atlantic, in Apr, at night, after striking an iceberg.

The practical explanation for this, of class, is that the writer of that novella had all-encompassing knowledge of ships and seagoing. But as a fun thought do (over again, non a serious theory), I like to imagine that these moments of sheer coincidence, in which events play out the style they did because of incredibly unusual coincidences, might exist the only bear witness of fourth dimension travel left to us. For want of a smash, indeed.
