We have planets moving around the sun at high speed, we have galaxies traveling like speeding bullets, billions of stars moving through space at tremendous speeds with their unimaginable masses. Let's do some math. <br /><br />mass of earth m=6x10<sup>24</sup> Kg. <br /><br />speed around the sun v=28962 m/sec (18 miles/sec) <br /><br />With these, kinetic energy, KE=(1/2)mv<sup>2</sup>=2.5x10<sup>33</sup> Joules <br /><br />Hiroshima bomb had equivalent energy of 8.372x10<sup>16</sup> Joules. <br /><br />Which means earth's kinetic energy is equivalent to 3x10<sup>16</sup> Hiroshima bombs. That is 30 million billion bombs. <br /><br />Our earth is absolutely an insignificant object in the universe. Now imagine how much energy was required to put all these objects in the universe in motion, if Newton's first law is correct? <br /><br />It is possible the concept of big bang arose from these enormous speed of massive objects, specially the fast receding galaxies. Can internal energies also set these objects in motion? Anyone wants to touch this touchy subject?<br /><br /><br /> <div class="Discussion_UserSignature"> <font size="2" color="#ff0000"><strong>Earth is Boring</strong></font> </div>
