I do not believe such a thing exists. Even considering the multiverse theorems out there, it would require much more energy than a human is capable of harnessing -- either naturally or artificially -- at this point, as far as we know.
But that does not mean you will not encounter people who believe they are making magical contact across plains of existence. Just be very careful of fantasy and make-believe. You could be pulled into a couterproductive group.
As far as i was taught all magick is interdimensonal
Our astral double projects the magick into the astral world and that is where the magick happens in this one..
The lesser banshing and middle pillar's would be nothing without us using our minds to imagine
A large part of my magickal practice has to do with accessing alternate dimensions to gain power for workings. For example, if I want to perform a healing spell, I will often access a dimension where that person is not and never has been sick and draw out some of that energy to pass to the subject of my experiment. I have, through this method, time and time again been met with excellent success.
It has become a bit of an annoyance that people think their beliefs and method of practicing are the only correct ones. It reminds me of the Christian Fundamentalism that I worked so hard to escape in my early life, and has no place among magickal people.
Much of my magical work revolves around summoning, so I am frequently with beings from other dimensions. I don't think using the dimensions to aid in your magic is far fetched at all. Shamans also learn to travel to these dimensions in astral form.
See, sidestepper: there have been several replies which prove my response. I do not believe personally that we can access other dimensions, but there are those who do. And there are also those who define the term a bit differently.
And I explained my belief without insult, opposite of what tou implied I did.
In terms of physics, in order to pass any of the known energy types between theoretical parallel universes, it would require immense amounts of energy -- think black hole singularity types of events. This is an amount of energy that a human being cannot access. But somehow you decided to create a dichotomy of all energy or none. You used a false dichotomy to create a straw argument.
But I also said there are those who believe it is possible, using magic, to communicate with other dimensions -- in terms of parallel universes. I never said they are wrong, only that I do not share that belief. There is no way to prove or disprove such personal gnosis.

Saying I did X is a false dichotomy.
X being "create a dichotomy of all energy or none"
Not sure where I said all areas use energy. I do recall mentioning areas which use energy.
Claiming "I" vs "You" could be considered an Ad Hominem. That said, it does help clairify.
Most arguments could be considered "Strawman". Largely because they are "set up" to be "knocked down". It is a false dichotomy to suggest they are not useful. Not that I am saying you are saying that. That would be an ad hominem.
Alas, stating terms is also just a "red herring", and distracts from the actual conversation.
Can personal Gnosis be proven? Well, there are methods of sampling that are used quite frequently in science. Psychology, for example, uses such sampling techniques. Though, correlation is not causation. That being said, when P-value is 5% then we can accept the null-hypothesis.
Of course, that is just Jargon indicative of my own educational background. For laymen it simply means with enough tries you can determine how reliable something is.
One could suggest that an inability to accept a possibility out right without taking the time to either research or try it could be suggestive of not accepting of science as a whole.
If you were, taking a scientific standpoint, you would have to rip a hole in the fabric of our universe (our dimension) and a hole in that universe/dimension which would take an incredible amount of energy, much more than a human would be able to harness. Talking is different, not much is known about the walls of our universe except that to destroy them would take a lot of energy, you might be able to talk through the walls, like yelling through a piece of corrugated cardboard, made out of pure matter and plasma. Good Luck!
So, we as humans experience three dimensions of space and one dimension of time. There are theoretically many more. I'm not sure why people are saying you need to "rip the fabric of reality" in this dimension and the one you are attempting to access. This is pseudoscientific woo taken from the pages of science fiction and fantasy, with nothing to support it in science or magick.
There is very little practical research done that we can refer to, but from my own study and experimentation, alternate realities are reached by "bending" them in toward you to align for a brief time with your own dimension and your perceptions thereof. Astral Projection, deep introspective meditation/trance/hypnotism, use of entheogenic substances, and ecstatic magick are just a few of the methods commonly used to attempt such a bending of reality.
