    I believe one day we definitely will. Even Lord Kelvin once said “Heavier than air flying machines are impossible” He was proved wrong, today we have big birds like A380 and 777 dominating the skies. What are the odds that we will achieve something greater than aeronautics?

      We have species of insects that can't even perceive our existence. What on earth makes us believe that we could even perceive a being or entities beyond our brain's processing powers?

                    The interesting part of all of this speculation is that...we are making predictions about how long things will take to be developed based on what we know TODAY. If science makes some catastrophically significant breakthrough in physics or quantum science/science, this all may change...just like things did with the projections of air travel just over a century ago. There were people in those days, science people, who declared outright that flight for humans wasn’t even possible. For some things, we don’t even know what we don’t know...and we won’t know until we look back on it. A device you can carry in your pocket with the amount of power a smartphone has was barely even thought of, realistically, in the late 1980s. They projected discoveries of technology, but within the framework of what we knew then. That’s what makes predictions so limited in scope.

                              I sent some other intelligent lives to discover you, humans. They came, saw Kardashians and flat earthers and some seriously stupid stuff, they looked back at me like this: 😐😐😐 .They lift off and decide to pretend they didn't discover shit and marked earth as a waste of discovery time and energy for other Intelligent lives. 😐

                                This makes me sad we are just the in between generation we never got to explore earth and will never get to explore space but we get to here about all the cool shit we will never get to experience.

                                                              But, if we are moving at the speed of light, wouldn't time stand still? Wouldn't we, like photons, arrive at our destination at the same moment we left? In which case we wouldn't see anything during the travel. It would be over the nano-second it began. For example, if I traveled 20 light years away at the speed of light, I won't have aged at all, but everyone I know back on Earth will have aged 20 years. Or am I thinking about it the wrong way?

In the video he says, "If you were to travel at the speed of light...." so I was thinking about it terms of already being at that speed. I totally glossed over the fact that you couldn't go from zero directly to light speed. You'd have to speed up to get there. Derp. LOL. And after watching it again, he does say "near" the speed of light. So yea, I was thinking about it wrong.

There would still be photons in your path that would hit your eyes, but it would be blueshifted. You wouldn't see anything of value, that is.

The propulsion conference was wrong. They are being closed minded, unable to look into the far future which requires imagination. Apparently those scientists don't possess that. in 1000 years humans will definitely be able to stop comets and meteorites on a collision course with earth-we could probably even do that now. if called upon-we could shoot loads of lasers at it to redirect it or send a nuc to blow it up. so humans will not go extinct. humans will be unbelievably technologically advanced in 1000 years, and in one million years i fully expect humans will be able to do stuff like manipulate higg field to alter mass and allow for a human spacecraft to be massless and be able to manipulate spacetime. I even believe humans will definitely avoid even the heat death of the universe. A highly advanced civilization might be able to break open a closed universe and change the topology of space-time , create its own pocket universe, reverse entropy, change matter into energy, cause particles to vibrate again,
