Of course, in the sense of it being changed from matter into energy, and vice-versa. But if it were possible to count and weigh and tally every last scrap of matter and energy present in our universe today, you'd find it was exactly the same as it was after the creation of the universe.<br /><br />See, matter can be converted into energy; you know this from Nuclear reactors and Bombs. Coversely, we can see a Supernova torch off, and see present later numerous forms of matter that were created in the intense fireball of the explosion.<br /><br />But it's really all just converting one into the other. Nothing "new" is created.<br /><br />When the universe was very young, it was much much smaller. And it was terribly hot - so hot that it was difficult for matter to form and remain so, so in that early soup of "stuff," matter was forming, falling apart, over and over again.<br /><br />But the universe expanded, and that same amount of energy and matter now had a lot more room to spread out in. So everything cooled off, and continued to do so. Today, we can detect the 2.7 K CMBR (Cosmic Microwave Background Radiation), which is the "glow" remaining fom that beginning, just like you can see a faint glow of heat from coals that was once a raging fire.<br /><br />That what you needed to know? <div class="Discussion_UserSignature"> <p><em>Differential Diagnosis: </em>"<strong><em>I am both amused and annoyed that you think I should be less stubborn than you are</em></strong>."<br /> </p> </div>
