Technoratiam I correct or wrong
AM I CORRECT OR WRONG? (NOTE THAT I MIGHT MAKE SOME STUPID MISTAKE BECAUSE I AM ONLY IN YEAR 10...):
A way to measure gravity --> gmn/r^2
A black hole gravity --> infinite
g is a constant
m is first mass
n is second mass
r is range of the two planets
either m or n is a black hole
m/n --> infinite
Lets say m = infinite
n is positive as cannot be negative and should not be 0
From now on i will call Whatever that is less than infinite but more than 0 --> X
infinite times X = infinite
infinite times n = infinite
Now it is g times infinite/r^2
g is positve so:
infinite times X = infinite
infinite times g = infinite
Now it is:
infinite/r^2
r is positive
r = X
X^2 = X
infinite/X = infinite
So if this is the case then any black hole would have infinite gravitational pull that acts over infinite distance
Time = K times 1/G
G is gravity
G is infinite in this case
1/G is the negative infinite
K is positive so G times K = negative infinite
Time = negative infinite
so in theory everything in the universe would be sucked in a black hole within negative infinite seconds...
BUT THAT IS NOT THE CASE AND HERE IS WHAT I THINK ARE THE REASONS
1) A black hole is a singulaity and breaks the laws of physics
2) infinite is not the higest number as there is no highest number, it is only a number so high that we cannot measure or write down, one infinite can be bigger than another infinite
if infinite is calculatorble in this case then infinite becomes X
When that happens then the gravity is no longer infinite but X so time is not infinite but X1 and distance is not infinite but X2 which makes sense
so in our real world it is either reason one or reason two
There is no such thing as a "black hole".
It's just made up nonsense, part of the same breed of crap that brought us "dark matter", "dark energy" and "dark funding".
1/g would not be negative, just really small
and the gravity of a black hole isn't infinite as far as I can rememer anyway.
Gravitaional forces fall off as 1/r2, so the force extends to infinity.
"infinity" is a philosphical absurdity though.
If you believe in gravity, it is a function of mass and black holes have a specific mass (at least two solar masses, but definitely not infinite, so the gravitational strength is not infinite. Black holes are black because at the surface, the escape velocity exceeds the speed of light; this btw was originally a reductio ad absurdum argument to prove that gravitational collapse (= neutron stars) was impossible, because if you exceed the Chandrasekar limit, then the escape velocity exceeds the speed of light and the consequences (black holes) were "unimaginable".
All you have 2 do then is apply Goedel's theorem.
If you dislike Black Holes, u can always deny the existence of gravity.
well funny you should mention that,
since basically all telescope observations reveal that
"gravity" fails to obey Newton's Laws when you get to galactic scales and beyond,
hence the need to "dark matter", "dark energy", "dark funding" and "dark tenure"...
I thought the real reason for dark matter was to stop the expansion of the universe; without the extra mass there is nothing to overcome the inertia of the big bang and we are forced to predict that eventually the universe will fade out of existence; add the extra mass and the expansion has a limit and after reaching a maximum it all rushes back together in an oscillating universe, a really repulsive model.
Er no, you need to go back to library!
The primary impetus for dark matter came initially from observations of the rotational movements of galaxies, and then clusters of galaxies.
They don't follow Kelperian orbital motion:
instead, all the stars seem to rotate around the centre with constant angular velocity!
ie. they move as if they were in big spokes of a wheel, similarly to Saturn's rings.
This is, of course, because stars are not powered in gravitionally-induced internal thermonuclear fusion at all, but because they a anode focii for galactic discharge currents :wink:
