Impossible?

Recently, on the Discovery Channel, scientists have confirmed the existence of more than one dimension in our universe.
Turns out that in every dimension of our lives can take place completely different or very similar ...what in our dimension is the past, as for example-the dinosaurs in another they may occur as the animals in the wild and no one is surprising;we do have a wife or a staggering career but when our lives in both dimensions are almost identical, then one experiences a feeling of De Ja Vu.
These dimensions are close to each other but do not penetrate each other, so there is no chance so we met each other ....However, scientists are working to create a black hole-type tunnel, which would allow the journey from one dimension to another.
Only if we will be able to find its way back? Suspected to be from different parallel universes slipping over each other ..
It is exactly like in the tv series Sliders-a boy-genius and his comrades travel to different parallel universes, trying to find their way back home.
And the movie is from 1995!!
What if Aliens are using these black holes to travel from one dimension to the other?
According to scientists, jumps to the parallel world is possible. What's more, this phenomenon still occurs in nature. We have alreadytechnology that allows us to observe neutrons traveling between dimensions.
