If I wanted to run a formula for the Volume of a Negitive Sphere on a computer which way would I write it?: V=(4pi/3)-r^3 or V=(4pi/3)r^(-3) or ? Has anyone else tried to run this formula on a computer? :shy:
PoPpAScience said:When one puts two mirrors in front of another, there seams to be an over lapping reflection, maybe into infinity. If at the moment of alining the two mirrors, the reflections take time to reflect back and forth into infinity, what would be a formula to describe this?
Even with pefectly reflecting mirrors, that would not work, because you need an integer number of photons with definite energy (color), as opposed to classical waves whose energy can be arbitrarily small.rgoudie said:each reflection absorbs an amount of light
PoPpAScience said:Tks Warren for your replies. I see I am going to have a hard time equating my thoughts on reverse expansion from a "Zero Point". The only time this can happen, is at the very beginning of our Universe. I can see it , but I can not express it. I feel the equation "(4pi/3)-r^3" would cover this, if a number generator starting at Zero is introduced to "r". This number generator can run into infinity, or have a stopping point. I have seen on tv animation where it looks as if you are falling forever into a smaller point (like a black Hole), or like my mirror example from before. This is the way I see it.
The current paradigm is that the expansion of the universe accelerates. That indeed implies an open universe with negative curvature. The fate of this universe would be a death due to dilution of energy.Zurtex said:I don't believe the universe is even close to a sphere.
As far as I understand "center of mass", this is mathematically defined as the barycenter point with respect to mass density weighting : this is a single well-defined spot. But the "center" of the black-hole is the singularity of spacetime, where the 4-curvature becomes infinite. This is classically a point where the General Relativity failure occurs. It is know strongly likely that QM theory of gravitation will somehow "blurry" the singularity, either through extended objects (strings) or due to granular spacetime (like in Loop Gravity) for instance.Zurtex said:a misconception of black holes is that the centre mass is infinitely small, this is not so
A negative sphere is an imaginary object that has a negative volume. It is commonly used in mathematical and scientific calculations, but does not exist in the physical world.
The volume of a negative sphere is calculated using the same formula as a regular sphere, which is V = (4/3)πr^3. However, in this case, the radius (r) would be a negative value.
No, a negative sphere does not have any real-world applications. It is a concept used in theoretical and mathematical models.
Yes, the volume of a negative sphere is a negative value. This is because the radius is negative, and when cubed, it results in a negative number.
The volume of a negative sphere is the exact opposite of a positive sphere. While a positive sphere has a positive volume and exists in the physical world, a negative sphere has a negative volume and only exists in mathematical and theoretical models.
