Practical Cosmology: Examples of How it Helps Our Ventures

AI Thread Summary
Cosmology has practical applications primarily in understanding the universe's large-scale structure and evolution, which can influence space travel and technology. Discussions highlight that while cosmology contributes to advancements in areas like cryogenics and detector technologies, its direct impact on daily life is limited compared to broader astrophysics. The conversation distinguishes between cosmology and astrophysics, clarifying that many cited benefits stem from the latter. There is a consensus that while cosmology is valuable for theoretical insights, its tangible outcomes are less pronounced. Overall, the practical implications of cosmology remain a topic of debate within the scientific community.

Not sure if this is OT for the cosmology forum.. pls move if so.

I'm wondering about examples of where cosmology science has helped in a practical way. Not being facetious.. genuinely curious (and I think knowledge for knowledge sake is almost always a good thing).

Cosmology has helped with our space travel ventures. Transpolar flights know to be guarded against solar radiation. And we know the effects that solar radiation has on electrical/electronic devices, weather and to some extent geological activity. We also know that solar radiation plays a part in evolution and genetics.

Physics on the other hand can be credited with many inventions and refinements.

In what other ways has cosmology had a practical outcome?

I don't think anything in the second paragraph is an outcome of cosmology.
 
I agree with Vanadium 50. The things you have cited, narrator, can reasonably be claimed as benefits from astronomy, since that is a more general and encompassing term. But none of them stemmed from the study of cosmology in particular. I supposed it could be argued that the industry of CMB observations has led to advances in cryogenics and millimetre and submillimetre-wavelength detector technologies. But those are about the only things I can think of. The reality is that the study of cosmology has very little tangible impact on the day-to-day life of the average person.

Hi narrator, I think you're confused about what 'cosmology' is specifically. "Cosmology" is generally a subset of astrophysics which describes the large-scale structure and evolution of the universe. This can be anything from soon after the very beginning of the universe, to the formation of the first stars, to the formation of galaxies and galaxy clusters etc.

Cosmology can also refer to a subset of theoretical physics, when applied to the very beginning of the universe itself: inflation, the creation of particles/matter, and dark matter/energy.

It sounds like you're referring more to 'astrophysics' in general (actually, it sounds like you're referring to another subset of 'astrophysics' generally referred to as 'space physics' which deals specifically with things like Earth's particular local environment, the solar system, etc.)

Wikipedia is always a good place to start:

https://en.wikipedia.org/wiki/Recombination_(cosmology) Was a matter density right after the decoupling low enough to consider the vacuum as the actual vacuum, and not the medium through which the light propagates with the speed lower than ##({\epsilon_0\mu_0})^{-1/2}##? I'm asking this in context of the calculation of the observable universe radius, where the time integral of the inverse of the scale factor is multiplied by the constant speed of light ##c##.
The formal paper is here. The Rutgers University news has published a story about an image being closely examined at their New Brunswick campus. Here is an excerpt: Computer modeling of the gravitational lens by Keeton and Eid showed that the four visible foreground galaxies causing the gravitational bending couldn’t explain the details of the five-image pattern. Only with the addition of a large, invisible mass, in this case, a dark matter halo, could the model match the observations...
Hi, I’m pretty new to cosmology and I’m trying to get my head around the Big Bang and the potential infinite extent of the universe as a whole. There’s lots of misleading info out there but this forum and a few others have helped me and I just wanted to check I have the right idea. The Big Bang was the creation of space and time. At this instant t=0 space was infinite in size but the scale factor was zero. I’m picturing it (hopefully correctly) like an excel spreadsheet with infinite...
