“Classical dynamics says if you know the state of a system at a particular time, this can tell us the entire history of the system,” said Germain Tobar, a student in the School of Mathematics and Physics at the University of Queensland.
“This has a wide range of applications, from allowing us to send rockets to other planets and modeling how fluids flow.”
“For example, if I know the current position and velocity of an object falling under the force of gravity, I can calculate where it will be at any time.”
“However, Einstein’s theory of general relativity predicts the existence of time loops or time travel — where an event can be both in the past and future of itself — theoretically turning the study of dynamics on its head.”
A unified theory that could reconcile both traditional dynamics and Einstein’s theory of relativity is the holy grail of physics.
“But the current science says both theories cannot both be true,” Tobar said.
“As physicists, we want to understand the Universe’s most basic, underlying laws and for years I’ve puzzled on how the science of dynamics can square with Einstein’s predictions.”
“I wondered: Is time travel mathematically possible?”
Tobar and his colleague, Dr. Fabio Costa from the Centre for Engineered Quantum Systems in the School of Mathematics and Physics at the University of Queensland, found a way to ‘square the numbers’ and their calculations could have fascinating consequences for science.

“Marty, Marty! Let’s go back in time to Nov 2016 and watch Hillary lose again!”
“ “Marty, Marty! Let’s go back in time to Nov 2016 and watch Hillary lose again!””
Now that would be a “Groundhog Day” scenario I would not mind exeriencing.

Even better, go back a few days early and bet all your liberal friends that Trump will win. Then relive election night by not only rejoicing all over again at their tears, but make them pay you for the experience as well!
I’d prefer Nov 2008...IF I could somehow perturb Obamao.
The problem is, the past isn’t there any more. You can’t go back to something that no longer exists.
Wow!
Trump has been doing this for years. :^)
If that’s the case, how many science fiction stories are now fantasy stories?
That’s excellent. thanks.
Uhh, sure, yeah. You first.
I came to this thread from the year 5780.
So the science isn’t settled?
Well where is my Gomer Pyle face?
Surprise, surprise, Surprise - Sergeant Carter you’ll never believe this!!
One problem with time travel that I’ve never had explained: the earth is not where it was in space an hour ago, let alone many years ago. And we’re not just talking about where it is relative to the sun in its orbit, because the sun and its solar system is moving though space; as is the galaxy.
So to go back or forward in time, one would have to move through space as well, find where you wanted to be and make sure you don’t materialize inside a tree or a wall.
Ok, then do it!!!! Similar to finding all those species that evolved from the previous “specie. “ Find those too. Fanciful buffoonery, just another clown filling up space to keep the money flowing in.
