It may take more than a nuclear-powered De Lorean or a spinning police box, but time travel could actually be a possibility for future generations, according to an eminent professor of physics.
Prof Amos Ori has set out a theoretical model of a time machine which would allow people to travel back in time to explore the past.
The way the machine would work rests on Einstein’s theory of general relativity, a theory of gravity that shows how time can be warped by the gravitational pull of objects.
Bend time enough and you can create a loop and the possibility of temporal travel.
Greetings, Earthlings!
I suppose you could attend your grandparents’ wedding or meet yourself. Interesting how the mathematics and the science eventually catch up with the imagination.
If people of the future become able to travel to the past, why don’t they come back and tell us how they did it? 🙂
Logically, the time machine should be Patent No. 00000001…
Wouldn’t time travelers have to also travel through space since the earth is moving as the galaxy expands? Traveling back and forth in time would mean one would also have to find out where the earth was, is or would be, at a given time, wouldn’t it?
If it will be possible it must already have happened. It hasn’t happened. Ergo, it isn’t possible.
No 6- for time travel to happen you need the first timeline in which we move from dinosaurs to present day to future to the invention of the time machine.
Then during the first visit a parallel universe is created in which someone did go back…and a paralel universe for each subsequent trip and that is where things get REALLY complicated.
For a general idea watch Donnie Darko then read a synopsis of it on the internet
I know what the first practical use would be–time machine snooze alarm clocks to set back time ten minutes so you could sleep in a few more minutes and still get to work on time.
#6 & #7, Larry Niven disposed of your arguments rather delightfully in his essay, “The Theory and Practice of Time Travel.” Summing up, he argued that, if time machines are possible, the universal timeline will be continually altered by time travelers until it finally reaches a state in which no time machine is ever built in that universe.
That is, of course, if the universe doesn’t follow Fritz Lieber’s Law of Temporal Stability (?) in which any changes to the past very quickly damp out so that the overall history of the universe is not changed.
#10 Fritz Lieber’s Law was explored ‘Back to the Future’. If his parents had not married, no Marty – a real dampener!
#10, you need a smiley there. 🙂
The illustration of the Law of Temporal Stability is Lieber’s first Time Wars story, “Try and Change the Past” — in which a man tries to prevent his own 32-caliber murder, only to find that — with the pistol removed from the scene — a 32-caliber meteorite hits him right between the eyes.
NWOA – did try the smileys, but they wouldn’t smile for me today. ‘Fraid my sci-fi reading was more HG Wells and Jules Verne. Interesting the Law is pretty close to reverse predestination. Thanks.
Must admit when I get into string theory and multiple dimensions my head starts to hurt.
