The universe |
Made some notes on paper , but asked myseelf if i'm right .
If as satellite flies to Mars , it has to go the other way then the earth .
And the energy needed :
Potential energy :
m * ( v2^2 / R2 - V1^2 / R1 ) * ( R2 - R1 )
Kinetic energy :
m * ( v2 - v1 )^2 / 2
Energy :
E^2 = E^2 potential + ( E kinetic earthroute - E kinetic marsroute )^2
with v1 = speed earth
v2 = speed mars
R1 = distance to earth
R2 = distance to mars
m = mass satellite
the tirth law of Kepler :
T^2 = cte * R^3 so
v = 2* Pi * R / T
v = 2 * Pi * ( 1 / cte / R )^0.5
it is independent of mass what the speed is of a certain distance . And you
need the changing of this speed for calculating the force needed .
So if you go to mars then you win in potential energy but you lose kinetic
energy . ( it's not the left - right vision but perpendicular )
And something else :
Time from big bang ( A ) / plancktime( B ) = Em force ( C ) / gravity of
protons ( D )
And mass of the universe ( E ) / mass proton ( F ) the square of the
previous comparison
So E / F = A^2 / B^2 = C^2 / D^2
E / A = F * C / ( D * B )
So the mass of the universe / time from big bang =
mass proton / plancktime * Em force / gravity of protons
Can you say then that there is birth of mass in the universe , that the
universe started with a little mass and that bij changing Em force you see
difference in massproduction , but the total amount of mass production stays
the same ?
And what if you multiply the mass of the universe / time from the big bang
with the spedd of removal of the universe ? Is that the force of the
universe ?

""""
V3 = 24.177 km/s
Comparing to
V2 = 21.632 km/s
we see that Mars is the one moving faster, and will be overtaking the
spaceship. To match velocities with Mars, the spaceship must generate an
extra boost of 2.545 km/s .
"""""""
If V2 is different of V3 , are the formula right then ?
They say the potential energy + kinetic energy = 0
But , isn't it perpendicular ?

Incomprehensible. Please rephrase.
And the energy needed :
Potential energy :
m * ( v2^2 / R2 - V1^2 / R1 ) * ( R2 - R1 )
Where did you get this formula from?
Kinetic energy :
m * ( v2 - v1 )^2 / 2
And this?
Energy :
E^2 = E^2 potential + ( E kinetic earthroute - E kinetic marsroute )^2
Why on earth do you add the squares of the energies?
with v1 = speed earth
v2 = speed mars
R1 = distance to earth
R2 = distance to mars
m = mass satellite
the tirth law of Kepler :
"third"

Why don't you run the numbers and then compare with empirical
observation? The Large Numbers Hypothesis is only that.

No.

No.
