Well when I watch movies I see space time as 2d. But how do we see the space time from Earth to a region lower than earth.
Space-time is 4D. But we cannot visualize this, so we usually just show a 2D slice, with the relevant dimensions.6thgrader said:Well when I watch movies I see space time as 2d.
There is no "lower than earth" in space. All radial directions (away from the center) are the same. Space-time along the radial line looks locally like shown here:6thgrader said:But how do we see the space time from Earth to a region lower than earth.
The fabric of space-time is a concept in physics that describes the four-dimensional continuum in which all objects and events exist. It combines the three dimensions of space with the dimension of time.
According to Einstein's theory of general relativity, the fabric of space-time is four-dimensional, meaning it has three dimensions of space and one dimension of time. Therefore, it is not accurately described as being either 2D or 3D.
Scientists have conducted numerous experiments and observations that confirm the existence of the three dimensions of space and the dimension of time. Additionally, Einstein's theory of general relativity has been extensively tested and has proven to accurately describe the fabric of space-time.
The concept of a 2D fabric of space-time is often discussed in popular culture and media as a simplified explanation of the complex concept of space-time. However, it is important to understand that this is not an accurate representation of the fabric of space-time according to current scientific understanding.
Some theories, such as string theory, propose the existence of additional dimensions beyond the four dimensions of space-time. However, these theories have not yet been proven and are still being studied and debated among scientists.
