ELECTROMAGNETIC FIELD OF EARTH INTRODUCTION The motions of the liquid iron and nickel outer core of the earth are thought to create the earth’s magnetic field. This magnetic field resembles a dipole as if a giant bar magnet was embedded inside. However, the axis of the dipole is not aligned with the rotational axis of the earth. Neither is it centered in the earth. EARTH'S MAGNETIC FIELDS PROTECT US FROM SOLAR WIND AND SPACE RADIATION. The Sun is a burning ball of gas that reaches such extreme temperatures that gas flies out from it at very high speeds. In fact, many of the electrons in the Sun’s atoms have enough energy to actually leave the atoms. The abandoned charged atoms are called ions. These ions and electrons flow outward from the Sun, and together they are known as the solar wind. When the solar wind travels with...
KUIPER BELT INTRODUCTION kuiper belt is an area of ou r solar system t hat is e stim ated to stretch across 20 AU of space.it is contains s mall asteroid and some big asteroid size of Pluto.this things made mostl y of ice and other g ases such as ammonia,nitrogen ,m eth ane and water. the kuiper belt ext ends from rough ly the orb it of neptu ne at 30AU to 55AU from sun.the main objects o f th is belt covers much of this r egion . FAC TS ABOUT THE KUIPER BELT 1. there cou ld be more than a trillion comet nucl ei in the main body of the kuiper belt. 2.the largest kuiper belt family members are pluto, makemake , haumen, lxion, quaoar etc. 3.the ices in the kuiper be lt data back to the formation of sol ar system . There have been more than a thousand objects discovered in the Kuiper Belt, and it’s theorized that there are as many as 100,000 objects larger than 100 km in diameter. Given to their small size and extreme distance from Earth, the che...
IS TIME TRAVEL POSSIBLE ?? IN TO THE FUTURE... We cannot avoid moving into our futures, but we can control the rate that we move through time. This is a consequence of another lesson from relativity: Not all clocks are the same. The speed at which you move through space determines the speed at which you move through time. In the succinct phrase: Moving clocks run slow. IF you could build a big enough rocket (don't ask me how, that's an engineering problem) to provide a constant acceleration of 1g (9.8 meters per second per second; the same acceleration as provided by the Earth's gravity at its surface), you could reach the centre of the Milky Way galaxy — a healthy 20,000 light-years away — in just a couple decades of your personal time. You could stop for a few hours, have a picnic near Sagittarius A* (the black hole at the centre of the galaxy), and then hop back into your rocket and come back to Earth. By th...
