AI Thread Summary
Gravitational shear is primarily associated with the focusing of light beams, particularly in the context of gravitational lensing, where it causes background galaxies to appear elongated. A calculation of Earth's orbital velocity reveals a velocity difference of approximately 1.27 meters/second between the side closest to the sun and the farthest side, raising the question of whether this difference can be classified as gravitational shear. The orbital mechanics involved indicate that this velocity difference is influenced by Earth's radius and its inclined orbit. While gravitational shear is commonly linked to weak lensing, the discussion suggests there may be broader implications or interpretations of the term. The exploration of gravitational shear's meanings extends beyond lensing phenomena.

Is there more than one meaning for "gravitational shear". It seems to refer to focusing of light beams.

When I calculate the difference in velocity, of Earth's side closest and farthest from the sun: the difference is about one meter/second. Is that gravitational shear?

Calculation

Orbital velocity is 2 times pi times the distance to the sun, divided by time, in this case the number of seconds in a year.

Velocity of Earth
v1 =2 * pi * 1.5 * 10^8 / ( 365.25 * 24 * 60 * 60 )
= 29.8653 km/sec.

v2 =(2 * pi * 1.5 * 10^8 - radiusEarth) / ( 365.25 * 24 * 60 * 60 )


Subrtact v1 - v2

The Radius of Earth is 6378 km.
The orbit is inclined to have a different velocity, at the sides nearest and farthest from the sun. This difference is, 1.27 meters/sec.

Usually, gravitational shear is mentioned in relation to gravitational lensing, mainly weak lensing. The shear causes background galaxies in relation to a foreground cluster to become elongated, and also curved towards the center of the cluster. Look up "weak gravitational lensing". . .
 
Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...

How does light maintain enough energy in the visible part of the spectrum for the naked eye to see in the night sky. Also, how did it start of in the visible frequency part of the spectrum. Was it, for example, photons being ejected at that frequency after high energy particle interaction. Or does the light become visible (spectrum) after hitting our atmosphere or space dust or something? EDIT: Actually I just thought. Maybe the EM starts off as very high energy (outside the visible...
