Title: Could we be living in more than 3 dimensions and just not sense it?
Post by: micron98 on 14/06/2014 06:51:39
Hi,
I have been thinking about multi dimension beyond 3d.

Our vision and sense is limited by our ability to see and touch and things we create.
What if we are tuned into current dimension?

For example, a FM radio to work, one need to tune the radio to specific frequency to hear clearly. Just by a few mhz off, you hear noise and a few more, cannot hear anything.

So what if our sense, vision, force are all tuned and we are only able to sense them with specific frequency?

Maybe there could be something much more faster than photon just that we are not tuned to see or sense them.

And in order to see the other dimension, we may need to increase energy level of ourselves or find a way to tune into it.

We know that at an atomic level, things are mostly empty space but I think it is not empty space. it is actually full of energy that is always surrounding us and trap us in current dimension.

If we are able to travel between the energy levels, we could sense dark force and dark matter.

It's not meaningful in physics to postulate things for which you don't have anyway to detect. You might as well be arguing about how many angels are dancing on the head of a pin. It's a useless theory. That and $1.20 will get you a cup of coffee.

Would that be a bit like suggesting that point particles are really vibrating strings?

Micron98, you might have to back up your ideas with some maths before scientists will take an interest.  I wish I had not slipped through the educational net where math was concerned; it’s the key to having your thoughts taken seriously.

I like reading , knowledge , thinking about physics but math that physicists do don't make sense to me.

I found an interesting youtube. However it is based on consciousness and I was surprised that one of speaker's description was quite similar to my theory.

It seems that theory of multi-dimension is not something that I can explorer here as it cannot be proved with calculation.
According to the video, I should know when I am on other side  [:D]

From what I hear there are theories which predict other dimensions. But it's my understanding that it can be verified so it's not what you're thinking, i.e. something that can't be verified.

Some of it is.  Some of it isn't explicitly verifiable yet (or more precisely falsifiable).  But the goal of all theories in physics is to be testable.

However, another feature all well-received theories have in common is that they make concrete predictions that at least match current observations.  That's why one has to do more than come up with a clever idea (which are a dime a dozen on the internet and are nearly universally incorrect).

Really!? That's quite interesting. I was under the impression that this is one of the things that the LHC was going to be searching for. See how wrong impressions gained through the news can be folks?

If we are living in nine dimensions - three we can "feel" and six that are far too small, then what would they look like if they were magnified a few zillion times?

OK, I suspect, you may say that they are mathematical concepts and don't have to mean anything - a bit like QM - but are they then real?

I don't mind shadows on a cave wall but if you're talking of mathematical caves and shadows only, where does reality occur?

The LHC can look for parts of certain theories that predict extra dimensions, but that's a small part of the various many-dimensions theories out there.

Oh, they'd be real if they are there.  Particles can move in these extra dimensions.  But we, being enormous compared to particle, can't move through these dimensions.  We should, however, be able to see their effects somehow.

It's a bit like subatomic particles.  We can't see them with our own senses, but with suitable experiments, we can detect them.  Plus, they're necessary to explain a lot of what goes on in the world.

Easiest way to think about it is to restrict one of our space dimensions so that if you step half a metre to one side you come back in from the other side and end up standing in the same place as you started. It makes little difference to anything if you make such a trip as you end up in the same place as you started. Restrict it further such that it happens on a 1cm scale and you won't have enough room to exist in, so you then need to start thinking about a fourth space dimension instead, giving all your atoms the ability to move about through this narrow dimension and giving them the ability to scramble you up. That would be a messy business, but you can then restrict it right down to the scale of atoms such that there is no scrambling of any molecules, although you may still mess up the way they atoms interact with each other. Restrict it down so much that it has no ability to scramble anything, and then it can have subtle effects without it being obvious that the extra dimension exists at all. There could be many such dimensions allowing things to wobble about sideways through them without any obvious side effects, but these extra freedoms may be vital for explaining how things work.
