1 <\/sup>Dayuling Super Science Center, Wang Chen, Changsha, Hunan, China<\/p>\n\n\n\n2 <\/sup>GL Geophysical Laboratory, USA<\/p>\n\n\n\nLike in the situation where there was no previous imaginary number i =\u221a(1) , , we can not solve equation x2<\/sup>+1=0. <\/p>\n\n\n\nWhat happens, if science did not accept imaginary number i=\u221a(-1) ?<\/p>\n\n\n\n
The same thing is happening: Invisible science problems cannot be solved if science does not accept “Positive Space and Negative Space”.<\/p>\n\n\n\n
We ask question : in polar coordinates of a two-dimensional plane, (\u03c1,\u03b8),\u03c1\u22650, is a point in the plane; for the same \u03b8, where is (-\u03c1,\u03b8) ? This question can interest students from middle school to university. This topic concerns professors and scientists at all levels. In this paper, we propose positive space and negative space and invisible science .<\/p>\n\n\n\n
Let ( x,y,z) be a point in 3D space, r = \u00b1\u221a( x2<\/sup>+y 2<\/sup>+z 2<\/sup>), the r =+\u221a( x2<\/sup>+y 2<\/sup>+z 2<\/sup>), used only as the radius of the point<\/p>\n\n\n\n ( r, \u03b8, \u03c6 ) of the 3D spherical coordinates in sciences previously. In 3D spherical coordinate, the set of the points<\/p>\n\n\n\n
( r, \u03b8, \u03c6 ) with positive radial coordinate,r \u22650, 0\u2264r\u2264+\u221e , called to be 3D positive space, the conventional three dimensional space we inhabit. For same ( \u03b8, \u03c6 ) of the points in the positive space, no point ( -r, \u03b8, \u03c6 ) exists in conventional three dimensional positive space. Thus, we propose a negative space, we now select the r =-\u221a( x2<\/sup>+y 2<\/sup>+z 2<\/sup>), a new negative space is defined as the set of these points (- r, \u03b8, \u03c6 ). In 3D spherical coordinate, the set of the points, (- r, \u03b8, \u03c6 ),with negative radial coordinate, -\u221e <r\u2264-0, is defined to be the 3D negative space.The origin +0 of positive space can be an arbitrary location. For a given 3D sphere coordinate in positive space, point, ( r, \u03b8, \u03c6 ),in the positive space and point, ( -r, \u03b8, \u03c6 ), in negative space are defined as corresponding points with the same latitude and longitude ( \u03b8, \u03c6 ). The origin +0 of the positive space and the origin -0 of the negative space are corresponding points, but distinct points. The 3D negative space is corresponding space of the 3D positive space.<\/p>\n\n\n\nBy 3D geometry knowledge, every sphere surface is a 2D double-sided curve surface or bilateral curve surface. The positive space lies on the outside lateral of the spherical surface, with the normal directed outward and with a positive radial coordinate ; the radius from the positive origin to the point is positive. The negative space lies on the inside lateral of the spherical surface, with the normal directed inward and with negative radial coordinate , the radius from the negative origin to the point is negative. The 3D positive space and negative spaces are not connected. The negative space and the positive space have no intersection. The negative space and the positive space are Euclid geometry space, Gravity, acoustic, elastic and electromagnetic equations and science hold true in positive space and negative Space.<\/p>\n\n\n\n
The debate on negative space theory resembles arguments over the scientific merit of Copernicus, Newton, Maxwell, and Einstein’s initial publications.<\/strong><\/p>\n\n\n\nPlease read “Based on negative space theory, an advanced GLHUA cloak discovered in [22] can be made from <\/strong>ordinary materials with a finite refractive index greater than one without metamaterials.<\/strong> Creating and product producing completely perfectly GLHUA invisible cloaks is not a myth but a practical task for the next step.”<\/strong><\/p>\n\n\n\n“<\/strong> <\/strong>The G sphere can be understood scientifically, and the negative space that induces it can also be understood scientifically.
