According to Theory fo relativity - that “borderline” radius of 2955 meters "is" the so-called [b]Schwarzschild’s radius[/b] of our Sun, and the gravitational potential on the surface of such an object is so strong it stops the course of time entirely, or in other words – time dilatation reaches infinite values with the Gravitational Blueshift (GBS) also being [b]infinite. [/b]The impact speed of everybody (on the surface of the[br]Sun) in this scenario equals the speed of light.[br][br]According to TT, in this scenario - nothing “dark or black” would happen:[br][br]The [b]gravitational potential [/b]would be [b]0.5[/b]; the [b]spacetime angle[/b] would be approx. [b]0.84 rad[/b] (48°); the [b]external velocity[/b] of the body (during impact) would be approx. [b]0.75[/b] while the [b]internal velocity[/b] would be[br]approx. [b]1.12[/b], which would be caused by a [b]time contraction[/b] of the value [b]2/3[/b] (meaning the time dilatation would be 1.5)![br]Not even the [b]Gravitational Blueshift[/b] (GBS) would be this close to the “limit”; instead - the value[br]would be “just” ca. [b]1.65[/b]![br][br]In the real world - the "creation" of a Black Hole will not occur – it is because the [i]sine[/i], [i]cosine[/i], [i]tangent[/i], and [i]exponential[/i] behave “reasonably” even in a strong gravitational field![br][br]More info at [color=#1551b5][url=https://timetheory.net/]www.timetheory.net [/url][/color]
