If we exclude time as the fourth dimension, is it possible that over many years of trial and study, that our thee-dimensional brains can comprehend a higher dimension?
Spastik_Relativity said:Just a random thought but would an aether be considered as another dimension or simply something moving through our three conventional dimensions?
If we exclude time as the fourth dimension
If we're in these dimensions right now, (let's assume) How come that over millions of years of existence, we still aren't able to "move" in a four-dimensional way. If we're in these dimensions, wouldn't our minds adapt to these dimensions over time?

General relativity is an extremely mind stretching way to think about the universe. And, why shouldn't it be? Humans evolved in a particular niche of space where the equation g=9.8 m/s^2 in the down direction. Human had no need to have any more sophisticated understanding. Additional understanding of gravity imparted no evolutionary advantage.
Likewise, in all but the last century of the hundreds of thousands of years of history, human have had no occasion to encounter matter engage in anything other than chemical reactions, except for a few naturally radioactive sites that could be chalked up to the much more plausible explanation of evil spirits. Why should humans understand quantum theory? And, in particular, why should they understand either nuclear strong force or nuclear weak force?
Humans are not finely tuned perceptual creatures. For example, we can't tell the difference between vision at twenty-four frames a second and a continuous view of an object. As long as we appeared in a common part of the 4th dimension every 24th of a second, who would notice the difference? Even artists, for example, took well over a thousand years before they could draw horses in motion with their legs the way they really worked, for essentially that very reason.
Now, don't get me wrong. A 4-D universe, three dimensions in space and time, would be a highly convenient physical relaity. BUt, imperfect human peception isn't necessarily the best argument for its existence.

Can you comprehend that?
3v1lk1djr said:Yes, but that is only a time continuum of a 3d shadow of a 4d object, not a 4d object itself
The 4th dimension refers to a theoretical dimension beyond the three dimensions of length, width, and height that we experience in our daily lives. It is often described as time or space-time.
The existence of the 4th dimension is supported by mathematical theories such as Einstein's theory of relativity and the concept of spacetime. Additionally, scientists have observed phenomena, such as gravitational waves, that can only be explained by the existence of a 4th dimension.
As humans, our brains are only capable of comprehending three dimensions. Therefore, it is difficult for us to imagine or visualize the 4th dimension. However, we can use mathematical models and computer simulations to understand and study the 4th dimension.
The 4th dimension, particularly the concept of spacetime, plays a crucial role in our understanding of the universe and how it operates. It helps explain phenomena such as gravity and the movement of celestial bodies. Additionally, technologies such as GPS and satellite communications rely on the principles of the 4th dimension.
While the 4th dimension may seem abstract, it has practical applications in fields such as physics, engineering, and computer science. Understanding the 4th dimension allows us to make more accurate predictions and models of the universe, which can lead to advancements in technology and innovation.
