Weird Life: Must Life Be Based on Carbon and Water?

چکیده
When we look up into the sky, it is hard not to think about how vast the universe is. Our universe is estimated to contain around 100 billion galaxies with each galaxy having around 100 billion stars. And most of those stars are expected to harbor planets. That is a mind-boggling number of stars and possible planets. This leads inevitably to questions about whether there is life on planets orbiting those distant specks of light. If so, what might it look like? Are there alien civilizations out there with intelligence and technology similar to or even more advanced than our own? If so, can we communicate with them?

متن کاملThe Effect of Carbon Nano-tube on the Fatigue Life of Asphalt Mixtures
The fatigue cracks are observed in asphalt surfaces much more than ruts. This paper deals with the influence of carbon nano-tube on the fatigue life of asphalt mixtures. These samples are made up of the slabs cut by the asphalt cutting saw. Fatigue beams contain 0, 0.3, 0.6, 0.9, 1.2, and 1.5 percent of Carbon Nano-tube. The fatigue experiment was conducted using a 4-point semi-sinusoidal loadi...
متن کاملEnvironmental education as a solution tool for the prevention of water pollution
Water is the origin of life. 3/4 of the Earth's surface is covered by water and all living things must have water to survive. Life without water can not be considered. Despite this, of all living things only humans exploit, waste and pollute this vital natural resource. Raising awareness of the people on this issue is of great importance. At this point, environmental education is a key concept....
متن کاملSensitivity analysis of parameters affecting carbon footprint of fossil fuel power plants based on life cycle assessment scenarios
In this study a pseudo comprehensive carbon footprint model for fossil fuel power plants is presented. Parameters which their effects are considered in this study include: plant type, fuel type, fuel transmission type, internal consumption of the plant, degradation, site ambient condition, transmission and distribution losses. Investigating internal consumption, degradation and site ambient con...
