So what reasonable expectation can we have from this mission?

We should be able to have far, far better constraints on the nature of the accelerated expansion. This kind of satellite can really do a great job at nailing that down. The website there mentions dark matter, but that's basically a solved problem, at least in terms of its effects on cosmology.skydivephil said:http://phys.org/news/2012-06-mission-go-ahead-probe-universe-darkest.html

Well, there are other ways to parameterize dark energy, but yes, this is essentially correct.skydivephil said:Are we talking about trying to measure w to a higher level of accuracy? If so the only revolutionary discovery will be if we got a non -1 answer right?

Well, what's usually done now is to take w_0 (the value of w today) and w_a (the derivative of w with respect to the scale factor a). But there are other possibilities as well. Either way, Euclid should offer some pretty tremendous constraints on dark energy compared to current constraints, no matter what sort of parameters you use.nicksauce said:I think they should also be able to measure/constrain the first time derivative of w as well?
The goal of this mission is to use advanced technology and scientific instruments to gather data and study the most mysterious and elusive objects in our universe, such as black holes, dark matter, and dark energy.
This mission will use a variety of cutting-edge technology, including powerful telescopes, advanced imaging techniques, and sophisticated spacecraft and probes. It may also utilize emerging technologies, such as quantum computing and artificial intelligence, to analyze and interpret the collected data.
By studying the universe's darkest secrets, we can gain a better understanding of the fundamental laws of physics and the origins and evolution of the universe. This knowledge can also have practical applications, such as improving our understanding of gravity, developing new technologies, and potentially discovering new sources of energy.
One of the biggest challenges is the vast distances and extreme conditions of space, which can make it difficult to gather accurate data. Another challenge is the complexity and unknown nature of the objects and phenomena being studied, which may require new theories and models to be developed.
The data collected from this mission will be made available to the scientific community and the public, allowing for collaboration and further research. It may also be used to inform and inspire the general public about the wonders of the universe and the importance of scientific exploration and discovery.
