you know what I got from that video?
Light is just not that fast. It only seems fast to us. I think at some point we are going to discover a whole new natural paradigm. The speed of light limit is just an illusion we are currently stuck in by our current limitations.
I wonder who the Einstein will be that will break this thing wide open and how far off is it?
It's important to note that due to time dilation, photons perceive no passage at time at all. So, really, at very high velocities it wouldn't feel like it was taking you a long time to get from one place to another. A lot can happen in that time frame of course but honestly our concept of time frames is at least partially to blame. Taking 10,000 years to travel (in what feels like almost nothing to us) is negligible on a galactic scale.
It's not really possible to exceed that speed limit in traditional terms as it would violate special relativity. Instead, it's more likely we would find a way around space. Many ideas are suggested for that, mainly ones involving changing the medium or using other tricks to shorten the distance rather than go faster. Personally (I have a degree in physics FYI) I believe the dark matter and energy existing between galaxies will likely provide us a solution, and traveling locally or to the edge of our galaxy won't be a big deal at near-light speeds once we shrug off our mortal frames. Again, even 10,000 years is nothing.
Keep in mind we'll still have the issue of information transfer which likely is a consequence of relativity because, theoretically, information could take the place of matter. Our understanding of black holes and other singularities is insufficient to know whether or not we could utilize them to bypass this limitation. Information theory is strongly linked to singularities for a variety of reasons but that is simplifying the issue.
How far off? A long time. I personally believe we'll be effectively artificial by that point and the problems that plague mankind today will simply no longer exist. One reason I suspect we haven't had alien contact is because any sufficiently evolved species will likely also be artificial and well beyond such concerns, keeping in mind an advanced life-form is much more interested in resource-heavy planets than ones that can support life.
