So this has to do with something called Dark Energy; I may dedicate a whole lesson to it. On small scales (small meaning the size of galaxies and smaller) Dark Energy isn&#x27;t strong enough to overcome gravity (or any of the other forces that hold stuff together). However in the void of space where gravity isn&#x27;t too strong, Dark Energy runs rampant pushing things apart at high speeds.<p>If I were to do the math on how much Dark Energy there was in my tiny universe, it might actually be the case that the asteroids should&#x27;ve been torn to shreds by the immense amount of Dark Energy. In fact, there used to be an interesting doomsday theory called the Big Rip, which went something like this: If Dark Energy got more and more powerful with time, eventually it would overcome gravity and start pulling apart galaxies, then stars, then molecules, atoms and subatomic particles. This scenario is no longer considered likely, but it&#x27;s still crazy to think about.<p>Dark Energy - <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Dark_energy" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Dark_energy</a><p>The Big Rip - <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Big_Rip" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Big_Rip</a>
