<p>Hi, Pradi_p.</p><p>&nbsp;Both Venus and Mars are visible in the western sky at the moment; you may indeed be seeing Venus as it is very bright.&nbsp; A bit farther southwest and you find Jupiter.</p><p>&nbsp;</p>

<p>From my general but relatively limited knowledge and grasp of physics, there is no reason in physical theory that the Universe must travel 'forward' in a time arrow. From what I've read (Kaku, Greene, et al), it can, theoretically, just as easily run backwards, effect to cause. Although, if we had the technological power to do such a thing, I don't think it would reverse or create anti-gravity. Neat stuff to ponder though...</p><p>Heck, reversing time would increase gravity on the macro scale if say, the Universe began contracting. Wouldn't it?</p> <div class="Discussion_UserSignature"> <p>ZenGalacticore</p> </div>

Someday relatively soon scientists will discover how gravity works, but I'm betting the answer will be found in one of the other seven dimensions that String Theory predicts.&nbsp; Until then, the only anit gravity is diet and exercise.&nbsp;
