We know some animals can interact/detect with magnetic fields and it isn’t fully understood. With all the talk about aliens having concerns with our nukes (because they damage more than we can perceive) it got me thinking, could humans have invisible aspects of our anatomy due to our inability to perceive a fourth dimension? What about animals?
How could we scientifically test for this?
By “four-dimensional”, I mean the three girls exist in four dimensions of space and one dimension of time as opposed to three dimensions of space and one dimension of time.
Found this article about scientists who created a light field that mirrors the structure of four-dimensional space. It's only in German, unfortunately, but there's a link to the original Nature publication in English at the end.
Particularly, representation of the fourth dimension and what the fourth dimension actually is. The "4D" movies always have scent and moving chairs...but I know that the fourth dimension is time.
If someone were to actually make a 4D animated movie or a 4D video game, how would this look? How is time represented graphically? What exactly is the fourth dimension?
Can we ever develop ways to view our 4th dimension?
The bare bones of some of our understanding of world geometry is laid out below. It has implications for consciousness studies because geometries akin to the Cartesian Theatre are permitted.
The constancy of the length of a rod (h) in three dimensions is given by a simple formula that uses the extension of Pythagoras' Theorem to three dimensions:
h^(2) = x^(2) + y^(2) + z^(2)
Where h is the length of the rod and x,y,z are projections of the object in the three independent directions in space.
You are probably thinking that this is a crazily complicated way of measuring the length of a rod but the calculation is actually about the independent dimensions attached to each of us, the observer. That the length of a rod can be calculated from how it lies in three dimensional space shows that there are no hidden directions in which the rod might be tilted: the rod seems to be wholly present in the three dimensions of space.
Until the twentieth century everyone thought that the three dimensions in space were all that was needed to describe the length of an object. Whichever way a rod is placed in space, the three dimensions of space that it occupies appear to always give the same value for the length of the rod. It is said that the length of the rod is "invariant" in three dimensions. This process of calculating a constant length from the projections of a rod on the dimensions in space is important because it shows that we seem to have captured all the possible ways in which a rod can be arranged.
However, in the twentieth century physicists made a monumental discovery, they found that the three dimensions in space are not sufficient to describe the length of a moving object. It was necessary to include time as a "negative" dimension and use a conversion factor "c" to express seconds as metres.
s^(2) = x^(2) + y^(2) + z^(2) - (ct)^(2)
The new, four dimensional length of the rod is "s" and remains the same, provided all four dimensions are taken into account, it is invariant however the rod is moved and also invariant between observers. "s" is known as the "space-time interval".
(The version of Pythagoras' Theorem given above is closely related to what physicists call the "metric of space-time" (which is ds2 = dx2 + dy2 + dz2 - (cdt)2). )
It is the nature of things to be four dimensional objects in a four dimensional universe.
The most interesting space-time interval is an interval of zero which permits simulta

Now mind you i am just an armchair scientist but while i was reading the other day and listening to some you tube i had an odd thought/idea. I would not mind being proved wrong just ask everyone is polite if they do not or like this idea.
Now. 3d space is measured in width, height and length if i am correct. and i understand how that works. But humanity also has one more measurement. time.
Time itself is another dimension we travel and can be measured. so my thought was.. what if that's the 4th dimension and the reason we have some issues. i got more here just wanted see anyone thoughts.
Saru isn’t being stupid offering Tilly the first officer position on a temporary, possibly permanent basis. He’s the Star Trek version of a Pierson’s Puppeteer, a scheming and manipulative herbivore descendant.
Remember, he immediately saw that the ship was turning sentient thanks to the sphere data and just rolled with it. He’s not slow on the uptake.
So why did he pick silly Tilly for his number one? He’s thinking four dimensionally. Literally. He wants to see how much of Killy is buried away in Tilly. After all, mirror universe versions of people aren’t wholly dissimilar, just dark reflections.
The magnificence of the universe is often overshadowed by negativity. When we think of space, we think of the vast emptiness and our insignificance as humans in that vast expanse. We focus on all the bad that can happen to us. But these four-dimensional superstructures are bringing beauty and wonder back into our lives.
An expanding balloon is often used as a metaphor for the expanding universe, as dots on the surface all get further away from each other like galaxies do. But does it violate any principles of relativity if we take the idea rather literally, albeit with one more dimension?
