Experiment with multiple instrument places all over the earth

AI Thread Summary
The discussion centers on designing an experiment with instruments placed globally to ensure at least one can observe the sun at all times. Participants suggest that visualizing the Earth as a circle can aid in understanding the problem. It is noted that since the sun is visible from one hemisphere, the maximum separation of instruments should be half the Earth's circumference. The confusion arises from the initial steps of solving the problem, emphasizing the importance of visual aids. The conclusion drawn is that proper visualization can clarify the maximum distance for instrument placement.

I want to design an experiment with multiple instruments places all over the Earth in such a way that at any time, at least one of the instruments can observe the sun. What is the maximum separation of instruments permitted?

I am really confused. Please help me with this!

please give some ideas about tem sir. I am just a class 9th student :)
 
Ideas about what? He said draw a picture! A picture of the Earth starts with a circle...

Ok! the sun will be visible from one hemispher for sure, am i right. So I think it should be 1/2 the circumference of earth.
 
Why the frown and uncertainty?

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

This thread is dedicated to the beauty and awesomeness of our Universe. If you feel like it, please share video clips and photos (or nice animations) of space and objects in space in this thread. Your posts, clips and photos may by all means include scientific information; that does not make it less beautiful to me (n.b. the posts must of course comply with the PF guidelines, i.e. regarding science, only mainstream science is allowed, fringe/pseudoscience is not allowed). n.b.
