![]() The research, which appeared November in the online Journal of Cosmology and Astroparticle Physics, found that while inflation isn't the only viable model of the early universe, other possibilities would require strange physics - such as a speed of sound faster than the speed of light. That's the question that University at Buffalo physicists Ghazal Geshnizjani, Will Kinney and Azadeh Moradinezhad Dizgah set out to answer with their study, "General Conditions for Scale-Invariant Perturbations in an Expanding Universe." The theory's conclusions about how the universe should look match observations by NASA's Wilkinson Microwave Anisotropy Probe (WMAP).īut is inflation the only model that can explain the beginnings of the universe? ![]() – The widely-accepted theory of cosmic inflation states that our universe expanded rapidly in the moments after its birth, resulting in the immense expanse we see today.Ĭosmic inflation explains why the universe is billions of years old, as well as why the universe is nearly flat. past perfect progressive Paul owes Paula 35 cents and has a pocket full of 5-cent coins, 10-cent coins, and 25-cent coins that he can use to pay her.BUFFALO, N.Y.

Therefore, at mid-ocean ridges, where new oceanic crust is created through volcanic activity and then progressively flows away from the ridge, seafloor spreading takes place. Massive basalt volcanic eruptions result from molten rock rising to the seafloor as the plates divide.Ī ridge's structure is influenced by how quickly it spreads slower spreading rates produce steep, erratic terrain, whereas faster spreading rates result in considerably wider profiles and kinder slopes.Ī huge network of underwater volcanoes known as the mid-ocean ridge system encircles the planet like seams on a baseball and stretches for about 65,000 kilometers (40,390 miles). What do you understand by the Mid - ocean ridge?Īs the Earth's tectonic plates separate, new ocean bottom is generated along divergent plate borders, which are known as mid-ocean ridges. ![]() ![]() At mid-ocean ridges, where new oceanic crust is created through volcanic activity and then progressively flows away from the ridge, seafloor spreading takes place. ![]()
