lots of energy needed for accelerating the earth

I read this somewhere in FE-theory: "there is no gravity, it's an fictive force. The earth is accelerating upwards at 9.81 m/s?."

I've some calculations:

• The speed the earth has now should be 1,39*10¹⁵ m/s, this is more then 4,5 billion times the speed of light 
• The energy needed to get to this speed is 2,415*10⁵⁹ J, this is the energy that is produced by the burning of 2,108*10⁴⁹ kg coal (this mass is approximately 10 quadrillion times the mass of the sun  )

Is there any explanation of the source of that massive quantity of energy?

some people believe that it is the same mechanism scientist refer to as 'Dark Energy'.

If we could get the same energy out of the earth as out of a nuclear fusion we need a mass of 3,513*10²⁰ times the earth. The amount of dark energy in the universe is something about 74%, there is also 22 % dark matter an 3,6 % galactic gas and 0,4 % stars, planets, etc.
Every star, planet, etc needs this great amount of energy to get this acceleration. And there is approximately 250 times the energy of the masses of the stars, planets, etc. and we need  3,513*10²⁰ times this mass, so it isn't possible.

If you could all mass convert to energy (e=mc?) and as I posted in my previous post there is due to dark matter and dark energy 250 times more mass than the one that's accelerating you can have an energy of 2,25*10¹⁹ J/kg. The energy that is necessary to get the earth at this speed is 4,04*10³⁴ J/kg. => you need more mass (1,80*10¹⁵ times more, only in dark energy and dark matter)

So we can make this conclusion: "There isn't enough mass in the universe to get this energy."

• The speed the earth has now should be 1,39*10^15 m/s, this is more then 4,5 billion times the speed of light 

The Special theory of Relativity allows any object with mass to accelerate forever and never reach the speed of light.

m=m(0)/(1-v²/c²)^(1/2)
F=m*a
=> There is always a bigger force needed for the same acceleration, if you get to the speed of light this force is infinity. In the Special theory of Relativity the maximum speed that can be reached is the speed of light.
=> You can't accelerate forever.

So you believe in the Special theory of Relativity but not in gravity or in a round earth. 

Except you can accelerate in your own FOR forever. As time slows down the same force will appear to give you the same acceleration.

In the Special theory of Relativity the maximum speed that can be reached is the speed of light.

Uh, I believe in SR no object can ever accelerate to the speed of light.

I've some calculations:

• The speed the earth has now should be 1,39*10^15 m/s, this is more then 4,5 billion times the speed of light 

Math, please. 

This thread proves nothing.

Isn't it nice to have Engy back? 

I don't know what you people did without me for all those months.

You call yourself "TheEngineer and you can't even calculate it yourself?
The earth is about 4.5 billion years.
A small calculation: 4.5*10⁹ year *365 days/year * 24 h/d * 3600 s/h = 5.913*10¹⁵ s
v=v(0) + at:
Lets say v(0) = 0 m/s
acceleration is 9.81 m/s²
v = 5.913*10¹⁵ s * 9.81 m/s² = 1.39*10¹⁸ m/s
speed of light: 3*10⁸ m/s
1.39*10¹⁸ m/s/3*10⁸ m/s = 4.63*10⁹
=> speed of earth is more then 4.5 billion times the speed of light

You call yourself "TheEngineer and you can't even calculate it yourself?
The earth is about 4.5 billion years.
A small calculation: 4.5*10^9 year *365 days/year * 24 h/d * 3600 s/h = 5.913*10^15 s
v=v(0) + at:
Lets say v(0) = 0 m/s
acceleration is 9.81 m/s?
v = 5.913*10^15 s * 9.81 m/s? = 1.39*10^18 m/s
speed of light: 3*10^8 m/s
1.39*10^18 m/s/3*10^8 m/s = 4.63*10^9
=> speed of earth is more then 4.5 billion times the speed of light

Oh.... I see what you did wrong.

GeertD, you can't apply a relativistic situation into a non-relativistic equation. Here,

Special Relativity forbids an object from ever reaching the speed of light.

w =     (u + v)     
        (1 + u*v/c²)



Where w is the new velocity, u (or 0m/s in this case) is the initial velocity, and v is the final velocity (or 9.8m/s for 1 second from universal acceleration). Now, after you find the w, plug it into the u on the new equation. Keep doing it until you reach 299,792,458m/s. Good luck.

What you are saying is:
u = 0 , u is the speed of the reference in space (earth in this case) => earth stands still
v is speed of object on earth
w is speed of object in space
if we calculate this we have the wonderful conclusion that v=w
if u and v are little compared to the speed light this is reduced to w = u + v
This is a complete wrong formula to prove this

F = m * a
m = m(0) /(1-w²/c²)^1/2

where m(0) is the mass at speed 0, w is the speed of the object in space and c is the speed of light
Here you can see that you need an infinit force to accelerate an object at the speed of light
=> acceleration stops

@ "TheEngineer": Do you want an explanation for the magic in your sign?

This an equation to convert the speed of an object on earth to the absolute speed with u the speed of the earth (in this case it's earth it could also be the moon or something else)

Then enroll in a Relativity course.

And check your math.  Your equations are wrong.

What's wrong with my equations?
a = dv/dt (classic and relativistic)
=> dv = a * dt
integrate this and you have (a = constant (constant acceleration of 9.81 m/s²):
v = v(0) + a*t
where v(0) =start speed

There is a power between to objects:
F = c* m*M/r²

where c is a constant factor this can be experimental verified
m is mass of object, M is mass of other object
r the distance between the objects

here: M is mass earth
m is the mass of the object (eg a person)
r the distance to the center of earth

There is a power between to objects:
F = c* m*M/r?

where c is a constant factor this can be experimental verified
m is mass of object, M is mass of other object
r the distance between the objects

here: M is mass earth
m is the mass of the object (eg a person)
r the distance to the center of earth

Wow, Nobel Prize in Physics here I come.

I don't think you can get a Nobel prize for saying you have an explanation or saying something is wrong without explanation.

Lol, everyone can see that you edited your post.

I had seen that if you want to get the "2" in superscript you can't use the key on your key board: it becomes a "?"
