There are some physicists who believe that time travel can be done.

At the University of Queensland, Australia a team of scientists have examined how time-traveling photons react; proving that, at the quantum level, the grandfather paradox-which makes time travel impossible-could be fixed. In the study, photons (single particles of light) to play out quantum particles traveling back from time. Through behavioral study, scientists have unveiled much stranger aspects of modern physics. 

“The properties of quantum particles are ‘uncertain to start with, so this gives them enough wiggle room to avoid inconsistent time travel situations. Our study provides insights into where and how nature might behave differently from what our theories predict,” says co-author Professor Timothy Ralph.

The Daily Mail further states: In the simulation, the researchers examined the behavior of a photon traveling through time and interacting with its older self. In their experiment they made use of the closely related, fictitious, case where the photon travels through normal space-time and interacts with another photon that is stuck in a time-travelling loop through a wormhole, known as a closed timelike curve (CTC).

Simulating the behavior of this second photon, they were able to study the behavior of the first – and the results show that consistent evolutions can be achieved when preparing the second photon in just the right way.

Physicists believe that due to Albert Einstein’s theories of general and special relativity, time travel is indeed a possibility. Special Relativity means that time and space are the same aspect, known as the space-time continuum, and time can either speed up or slow down, depending on your speed, relative to something other.

General Relativity states that it would be entirely possible to go back in time through a space-time path. In 2012, physicists Serge Haroche and David Wineland shared the Nobel Prize in Physics for the demonstration of “quantum weirdness” and how it can’t exist at the subatomic micro-world level, and how it can appear itself in the macro-world.

“The question of time travel features at the interface between two of our most successful yet incompatible physical theories – Einstein’s general relativity and quantum mechanics. Einstein’s theory describes the world at the very large scale of stars and galaxies, while quantum mechanics is an excellent description of the world at the very small scale of atoms and molecules,” says Martin Ringbauer, a PhD student at University of Queensland’s School of Mathematics and Physics, and a lead author of the paper.

In a documentary from the BBC, astrophysicist Stephen Hawking finds that it isn’t possible to go back into time. There isn’t a lot to look forward to at all.

Now, there are some developments in quantum theories that could deliver understanding of how to take on time travel paradoxes.
