Paradox-Free Time Travel is Mathematically Possible: Study
Sci-news ^ | 09/25/2020

“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.

“Think of time as a continuous flowing stream with no beginning nor end.”

Is there a reason why I should?

"Are those quotes from the article or the paper?"

I don't know, but they are quotes from the author. That tells me enough.

Actually no. They disconnect the soul from the body but drug users usually get stuck in the lower frequency dark realms.

A friend of mine is an ER physician at a major metro hospital and he asked me why the drug users that OD and die tend to pop back into their bodies and come to life when it is beyond reasonable, while accident victims tend to die and leave their bodies without returning when their injuries are not that bad.

It has to do with the amount of pain experienced when they depart the body. Drug users tend to have less physical pain so they are more likely to return.

Why did an ER physician at a major metro hospital ask you that?
