Blast from the Past! What is the Distance to the Moon?

One little error - the speed of light is just UNDER 300,000 Km/sec to be exact 299 792 458 m / s in a vacuum.

There should definitely be comments on such a jovially narrated video! General Relativity says that things with mass generate acceleration and movement of objects in space by warping the fabric of space-time. This warp in space time, simply put (??), shortens the distance between objects in space allowing them to move towards each other and to move fast! Special Relativity says that the faster you go, the slower time takes, and so its possible to travel at great speed but not experience the same passage of time as one would on earth. I'm not sure about the maths but it's something like travelling at 99% light speed 'c' means you can travel 7 light years in one 'earth year'. Hence, a technology that is able to warp space time by replicating and enhancing the affects of mass would allow us to accelerate fast and travel to and from Proxima Centauri (9.4 light year round trip) in about 1.3 years. So this is for 'us' travelling at 99% 'c' - we will surely find the technology to 'squish' spacetime easility enough within the next 100K years - possibly within 10K years? HOWEVER - the great news is that we don't have to wait that long to find out what's out there. We can already accelerate protons to 99.999999.1c which means that time passes an enormous 7460 times more slowly for the protons than it does for us humans. A trip for a particle traveling at that speed from Earth to Proxima Centauri would measure a journey time of under 5 hours (a 10 hour round trip). Furthermore, we can quantum entangle particles so that one particle at Proxima Centauri can send information back to us on earth within 5-10 hours (I'm not sure about the real time for sending quantum entangles info - lets assume its not instant and takes 5 hours so we don't blow a hole in the light speed limit). So, all we need to do is to fire 100Billions of beams of quantum entangled particles (accelerated by the LHC) out into every corner of the galaxy and let them report back to earth their findings. Maybe it will take us between than 100-1000 years from now to find a way to entangle and fire out beams of particles which are capable of reporting back information. So, we would have the galaxy mapped within 40 years of starting - a mere 140 years from now. Eat your veggies, exercise and save up so you can afford to take advantage of gene therapy and you may just live to see it!
