Why can’t I go faster than the speed of light?
Q1. Does the future already exist? I realize this might be purely philosophical, but if I leave Earth, and fly through space near c kph, and return home a few hours later to find everyone aged 50 years... are they the &quot;same&quot; people, or are they a future-instance of the people left? To clarify, theoretically I could leave earth, and return home in exactly 1 hour (from my ref frame), and basically make people whatever age I want by varying my speed. Since the same 1 hour passes for me no matter the age for them I chose, it seems like I&#x27;m selecting an already existent future from a stack, not fast-forwarding the present I left.<p>Q2. How do black holes exist if time stops inside a black hole? That is, they continue to move through spacetime, even though spacetime is not moving within the hole? I accept that a black hole can form, and can stop time, I&#x27;m just curious how something that stops time continues to persist in the present. The way I&#x27;m visualizing this, is like a lava lamp about to bleb off some goo from the top [1]. As the object gets more and more dense, it curves and drags spacetime more and more, until eventually its density passes the Schwarzschild radius and blebs off.<p>[1] <a href="https:&#x2F;&#x2F;m.media-amazon.com&#x2F;images&#x2F;I&#x2F;615deDvfDkL._AC_SS450_.jpg" rel="nofollow">https:&#x2F;&#x2F;m.media-amazon.com&#x2F;images&#x2F;I&#x2F;615deDvfDkL._AC_SS450_.j...</a>
