What is the 3rd dimension? - Relativity - Science Forums
2020年10月14日 · You can visualize each by moving 90 degrees away from every point along the previous dimension (moving from a line to a plane, then from a plane to a cube). The third dimension is equally pictured as height, depth, and thickness, and lends a quality to objects we think of as solid.
Can you make a concept of the 5th dimension?
2011年8月21日 · We know that the 1st dimension is length (a line), the 2nd dimension is length + width (a polygon), the 3rd dimension is length + width + hieght (a cube), and the fourth dimension is length + width + hienght + time (a moving cube). Does anyone know what is the 5th dimension? Is it heat, colour, c...
Why is time considered the 4th dimension? - Science Forums
230. 752. Posted March 7, 2012 (edited) Time is labelled as the fourth dimension in relativity because it is in many ways interchangable with the three spatial dimensions. In SR, the spatial dimensions in one frame are a mixture of spatial+time dimensions in another.

What is the 5th Dimension exactly? - Science Forums
2013年9月23日 · The second dimension has two axes, the [math]x[/math]-axis and the [math]y-axis[/math] forming the [math]xy[/math] plane. Likewise, the third dimension has three axes forming an "xyz space" (very informal wording). When we go beyond the 3rd spatial dimension, things get hard to visualize, but conceptually it all follows the same basic principle.
Possible explanation for Dark energy, Dark Matter and the 4th …
2011年7月13日 · 3rd: xyz-axis Now, for the 4th dimension, lets say we had a sphere in the 3rd dimension and measures 1 unit in each direction. The 4th dimension would expand the sphere in all three directions without changing the 1 unit length of the ball. Therefore, the 4th dimension is the ability for expansion of matter.
Why ct instead of t - Relativity - Science Forums
2006年2月8日 · Higher level books on relativity do use t for the 4th dimension. ct is used in elementary treatments because students are still used to old systems of units (SI, English, what-have-you) that necessitate a conversion factor c with the dimensions of velocity.

Can you really square a second? - Science Forums
2020年10月20日 · g (or a) is coefficient used in equation of distance traveled by body i.e. d = 1/2 * a * t^2. "second square" unit of a, cancels out with "second square" unit of t^2. Simple cancellation of units. m/s^-2 * s^2 = m. To calculate acceleration of the body, you transform this equation from. d = 1/2 * a * t^2.
Does our consciousness exist in a higher dimension?
2010年1月12日 · It can be argued that we are interdimensional beings since we can physically enter the 1st, 2nd, and 3rd dimensions. Although it is impossible to physically represent a 4th dimensional object, our brains are still able to imagine or see a 4D object purely in thought, which seems to me should be impossible if our brains existed only in just 3 ...
