AI Thread Summary
The cosmic microwave background (CMB) temperature variation is not static and changes over time. There is a gradual increase in wavelength, indicating temporal variation. Additionally, the structural patterns of the CMB, which can span 10 Megalightyears, also evolve over a time scale of approximately 10 million years. This suggests that both spatial and temporal changes are inherent to the CMB. Overall, the CMB's pattern is dynamic and subject to change.

Is the pattern of temperature variation of the cosmic microwave background static, or does it vary over time?
 
Astronomy news on Phys.org
It varies with time. First of all, you have a slow increase of the wave length with time. Second, you have the pattern. This will vary in time just like it varies in space in a sense that when typical structural patterns are 10 Megalightyears in size, they will also change on a time scale of 10 million years.
 
Excellent! Thank you very much.
 

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. In case of failure to detect...

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...

Thread 'Could fast radio bursts be alien radar signals?'

Both have short pulses of emission and a wide spectral bandwidth, covering a wide variety of frequencies: "Fast Radio Bursts (FRBs) are detected over a wide range of radio frequencies, including frequencies around 1400 MHz, but have also been detected at lower frequencies, particularly in the 400–800 MHz range. Russian astronomers recently detected a powerful burst at 111 MHz, expanding our understanding of the FRB range. Frequency Ranges: 1400 MHz: Many of the known FRBs have been detected...
