Though we may appear to be quite satisfied with the possibility of defining location of a point by specifying its distances from the reference-point – known as the “origin” – by assuming that the coordinates of the origin are 0, 0, 0 it can’t be denied that the system of defining the location of a point through only three basic dimensions, does not give us even a hint whether the point is stationary or mobile.
We know that the Sun travels at a speed of 230 km per second around the center of the Milky Way and the Earth travels at an average speed of 29.78 km per second around the Sun. But the Sun does not travel alone. It carries its all planets also along with it. So effectively the Earth covers a distance of 259.78 km – not merely 29.78 km per second.
It leads us to assume that an extra dimension gets added to an object if it revolves around an object that may be also revolving around some other object, just like the Earth.
I may make it clear that when we talk of extra dimensions, we talk of such dimensions only.
Much the same way, you would find that a dimension gets added if something may be revolving around an axis and the axis may be also moving around some other object the way the planets move around the Sun.
To conceptualize the existence of multiple dimensions just think of an aeroplane flying over you in the sky.
We may specify its location through the following coordinates.
- The latitude, say, Θ°.
- The longitude, say, Φ°.
- The altitude, a above the ground level or above MSL.
- The time, τ expressed as the date and the GMT.
We may add the angle Ψ°, howsoever small, by which the Greenwich line may have turned around since midnight as the fifth dimensions of the aeroplane.
Now think of adding the angle by which the axis of the Earth may have wobbled around from its position at the midnight as the sixth dimension of the aeroplane.
But the Earth is not simply revolving around its axis or is not just wobbling in the space. It is also revolving around the Sun as shown below.
If we may treat the angle the Earth may have subtended to the major axis of its orbit at the midnight as 0° and it may have travelled through an angle α° since midnight, we may treat the angle α° as the seventh dimension of the aeroplane.
But when the Sun heaves above the Galactic plane or heaves below the Galactic plane as shown below the Earth also heaves along with the Sun and so does the aeroplane.
This adds the distance of the Sun from the Galactic plane as the eighth dimension of the Sun and 1, 2 3 or 4 as the ninth dimension, as follows.
- If the Sun may be moving away from the axis (Galactic plane) upward.
- If the Sun may be descending toward the axis from its zenith.
- If the Sun may be moving away from the axis below the Galactic plane.
- If the Sun may be ascending toward the Galactic plane upward.
Now think of the movement of the Sun along its orbit around the center of the Milky Way.
It carries not only the Earth actually it carries all of its planets along with it when it revolves around the center of the Milky Way. No wonder, the aeroplane also moves at a speed of 29.78 km per second along with the Earth around the Sun and at a speed of 230 km per second along with the Sun.
If we may regard the angle the Sun may be subtending to the Sagittarius at the midnight as 0° and it may be subtending angle β° at the time τ, the angle β would become the tenth dimension of the aeroplane.
The way the aeroplane seems to have ten dimensions, the physicists are of the view that the subatomic particles should also have some additional dimensions.
But it is not yet clear how long it may take them to establish such possibility according to Quantum Mechanics.
