Scientists realized that under the ground lay an energy producing gas waiting to be extracted. Today when a company is looking for natural gas, they seek out a particular type of rock formation above ground. Tests are run that can measure sound waves and gravitational pulls in a particular area. If the tests appear promising, the drilling begins. Drilling only returns natural gas half of the time. In order to tap into the underground reserve, the drilling team must dig about 6000 feet into the ground

Armando I Cortes Nov. 17. 2025 Mrs.Lisa Smith The Formation of a Star The basic idea of star formation is gravitational collapse – the contraction of a region of gas under the influence of gravity. This is a simple process that would be expected to occur in any region of material dense enough for collisions between atoms to radiate away energy. However, the gas must be dense enough for collisions to occur and the temperature must be low enough for the atomic velocities not to be able to escape

Abstract Eight planets, fifty-eight moons, thousands of asteroids, and billions of meteoroids and comets and one dwarf planet named Pluto orbit the grand star, the Sun. Around and around they go. These planets and other object came from a huge explosion. The Big Bang Theory, which states that the universe began as a dense and hot point that was less than a fraction of an inch and has continued to evolve into what it is known as of today. The origin of the galaxy seems a mystery. But over time

Chapter 2 Theory Motion: In physics, motion is a change in position of an object with respect to time. Motion is typically described in terms of velocity, acceleration, displacement

------------------------------------------------- Structure of the Interior of Earth Earth has a diameter of about 12,756 km (7,972 mi). The Earth's interior consists of rock and metal. It is made up of four main layers: 1) the inner core: a solid metal core made up of nickel and iron (2440 km diameter) 2) the outer core: a liquid molten core of nickel and iron 3) the mantle: dense and mostly solid silicate rock 4) the crust: thin silicate rock material The temperature in the core is hotter

Background of LISA detection rate: LISA is a joint ESA–NASA mission aiming for cosmic gravitational wave detection and analysis. It has been shown that the passage of one asteroid in the neighborhood of one of the LISA spacecrafts can generate a signal detectable with the standard LISA data analysis, and this has led to the issue of quantifying the rate of such events. P Tricarico et.al do a lot of research on LISA detection technique[2006,2009]. In 2009, he proposed a method to evaluate the

causing this.” “Alright, well thanks for the update.” Harold hangs up the phone. “Radio waves?” Dr. Winford wonders out loud. “Why would it be emitting radio waves?” Harold questions. “Is it sending a signal?” Dr. Winford deliberates. “What signal would it be sending, and for what purpose?” Harold asks. “We need to be intercepting those radio waves now!” Dr. Winford exclaims. 6:02 PM “It seems the radio waves we’ve intercepted from the outer-galactic object has been nothing but white noise.” A
