The Food and Drug Administration (FDA) does not recommend that you get ultrasounds done for fun or bonding purposes, citing the use of ultrasound as a medical technology. With three dimensions the space is shown by coordinates, while the four dimensions of the time (t) are not displayed in that coordinate system with some angle (dimensional) that is constant or real. As such, the concept of 4d has arrived – based on the Einstein’s theory of relativity – where the time is added as an additional variable. 3 dimensional or something and how can they keep adding dimensions to … So 4D radar is just a sales-promoting buzzword that has nothing to do with the fourth dimension in physics.
