Scientists have created the most accurate way yet of simulating the way the universe expands. Dubbed "gevolution", the tool will for the first time allow researchers to take into account the effect of ripples in spacetime - known as gravitational waves - and could help shed light on dark energy, the mysterious force driving the universe's accelerated expansion.

The article is about how with the discovery of gravitational waves, they are creating a model that will now have the element of gravity/ 'the effect of ripples in space-time'. This will allow researches to now explore dark energy and if it exists. Here the Stakeholders are scientists and programmers making the model and simulation. The scientist, as they will be using the simulation and the programmer as they'll create the programs for it to run on. Mathematicians too will be involved, as they will have to take what is research and transform in into equations. The main social ethical significance will be that science advancing forwards with a new understanding of the universe we live. This will allow us to come up with new models for everyday life as well as optimization of existing models. However some people see this idea as a waste of time as the newton's model work well already at simulating the universe. The new model however will cost a lot and time to program the software involved, but will allow for a greater degree of detail and accuracy to models of the universe. The main IT systems involved are super computers that have to compute the models of the universe inside them. These will have to compute complicated equation together to then develop a simulation that can be further observed by researches. Software will be a major aspects as it will have to be programed to use new equation along side exist equations to generate a new model.

Both models each serve the specific needs and circumstances of the environment where the software is to be deployed. And such needs and circumstances ultimately determine what factors are relevant and applicable, and whether certain advantages and disadvantages of the open source or commercial software model should be given more weight and consideration in determining the approach for that implementation and deployment.

For many, new health insurance is not providing access to affordable care, and the ACA will not address the physician shortage. To bridge that gap, we must find innovative ways facilitate hassle free access to a provider that is more cost-effective. Telemedicine is a growing model that is a part of the answer.
