New model ‘permits time travel’

The concept of time-travel is laden with uncomfortable paradoxes
|
If you went back in time and met your teenage parents, you could not
split them up and prevent your birth - even if you wanted to, a new
quantum model has stated.
Researchers speculate that time travel can occur within
a kind of feedback loop where backwards movement is possible, but only
in a way that is “complementary” to the present.
In other words, you can pop back in time and have a look
around, but you cannot do anything that will alter the present you left
behind.
The new model, which uses the laws of quantum mechanics, gets rid of the famous paradox surrounding time travel.
