Exploring the Impact of Space-Time on Falling Apples

In summary, the space-time curve affects the apple's movement by creating gravity, which is not a force but a curve in space-time. The surface of the Earth is accelerating upwards due to pressure in its core, causing the tree and apple to also accelerate upwards. However, the inertia of the apple causes it to lag downwards, putting tension on the stem and branches. When the stem breaks, the apple continues at its current speed while the tree and ground continue to accelerate. This explanation takes into account the concept of space-time curvature and how it allows opposing sides of the Earth to not drift apart despite their seemingly opposite movements.

I've been wondering since a long time how does the space time curve affect the apple. If the apple isn't attracted by any force but because of the space time, then help me visualise the correct picture of space time which makes the apple fall on the earth.

The surface of Earth is accelerating upward (due to the pressure in its core), pushing the tree to accelerate upward, pulling the apple stems to accelerate upward. By the inertia of the apples they lag downward and place tension on the stems and branches (and pressure on the roots and everything below). If the stem breaks then the apple stops accelerating and keeps going at the speed it already had, but the tree keeps on accelerating upward and the accelerating ground catches up with the apple. Just like if the apple tree were in a rocket-elevator in outer space.

Where does space-time curvature come into it? It allows the opposite sides of the planet not to be getting any further apart, despite their accelerating in seemingly opposite directions.

To cesiumfrog,
I'm not talking about Newton's discovery. If you have ever read about space time, you would surely know that it is the space time curve that creates gravity. Gravity is not a force. It is actually a curve in the space time. I want my answer in this context.

Cesiumfrog's claim that "The surface of Earth is accelerating upward (due to the pressure in its core)" is non-sense anyway.

No its not, his description was actually exactly what the OP was asking for.

The apple "accelerating" downwards is not actually an acceleration in GR but instead it is its movement along a straight line aka it have no acceleration. When it lies still it don't move according to a straight line any more and thus it must be accelerating, as such if you implement GR every part of the surface is accelerating upwards while if you throw an apple it stops accelerating upwards, while the rest do accelerate upwards making it look like the apple is accelerating downwards when it is actually the other way around.

@thinker93: read again, cesiumfrog gave the answer.
 

1. How does the concept of space time apply to apples?

The concept of space time refers to the interconnected nature of space and time. In the case of apples, space time affects them in terms of their growth and ripening process. The position of the apple in space (i.e. its location on a tree) and the time it spends in that location both play a role in its development and maturity.

2. Does the gravitational pull of objects in space affect the growth of apples?

Yes, the gravitational pull of objects in space, such as the Earth or the Sun, can have an impact on the growth of apples. This is because gravity affects the distribution of nutrients and water within the apple tree, which in turn affects the growth and development of the apples.

3. Can time dilation affect the taste of apples?

Time dilation, which is a phenomenon in which time moves slower in the presence of strong gravitational fields, can potentially affect the taste of apples. This is because the longer an apple remains on the tree, the more time it has to absorb nutrients and develop its flavor.

4. How does the curvature of space time affect the trajectory of falling apples?

The curvature of space time, as described by Einstein's theory of general relativity, affects the trajectory of falling apples in the same way it affects the trajectory of any object. As the apple falls towards the Earth, it follows a curved path due to the curvature of space time caused by the Earth's mass.

5. Can the expansion of the universe impact the growth of apples?

The expansion of the universe, which is the theory that the universe is constantly growing and expanding, can potentially impact the growth of apples. This is because as the universe expands, the distance between galaxies and stars also increases, which could potentially affect the amount of light and energy that reaches the apple tree, ultimately impacting its growth and development.
