Today Catching Up With Tomorrow

We are living in the future!

This week marks a cinematic milestone. Tomorrow, the 21st of October, 2015, at 7:29pm Eastern time (4:29pm California time), will be the precise moment when Doc, Marty and Jennifer arrive in a flying DeLorean from the year 1985 (as depicted in the film Back to the Future Part II). In that movie, there were some really fascinating technological achievements displayed in that 1989 version of 2015. And with a few exceptions (flying cars, hoverboards), we are living, or on the verge of living, in a world where much of that technology is a real part of our lives.

The smartphone alone accomplishes much of what would have seemed unbelievable 26 years ago. There is not much depicted in that film that we have not yet accomplished or are not working steadfastly towards accomplishing. We might be approaching an 'innovation event horizon', where we are no longer able to be innovative, but instead we focus on being efficient.

Some examples: these technological advances which were once considered futuristic science fiction are all part of our reality: Cloning, replicating materials (a.k.a. 3d printing), life extension, space colonization, time travel, flying cars, giant fighting robots, virtual reality, flying robots, hyper personal advertizing (ie Minority report), etc. It can't be long before even flying cars are a part of our reality...when the technology of drones mixes with self driving cars, self flying cars are sure to follow.

If you have doubts that we're living in a radically futuristic age, then here are some recent headlines to back up my argument:

For the time being though, where we're going, we still need roads.

Distance To Hill Valley (in 1985)

We are on the verge of a major cinematic milestone – this coming Wednesday, October 21st at precisely 7:29 pm Eastern time (or 4:29 pm California time) is the moment when Doc, Marty and Jennifer will arrive from 1985! It's hard to believe that this date, from the movie Back to the Future Part II, which once seemed like the distant future, is nearly upon us.

One thing that kind of annoys me in movies about time travel, is that they rarely take into consideration the movement of objects in space. I guess they are taking for granted that as they travel through time they are also traveling through space, and very rapidly, or else time travelers would find themselves in some interesting places.

Doing some rough math, and knowing that the Solar System moves 250km per second through the Milkyway, and that the Milkyway is moving 300km per second through space in our local cluster of galaxies (and not taking into account leap days, or that the Earth spins at 1/2 km per second)...

(300 km/s (galaxy speed) + 250 km/s (solar system speed)) x 602 (seconds per hour) x 24 (hours per day) x 365 (days per year) x 30 (years since Doc Marty and Jennifer left 1985) = 520,344,000,000 km!

...that exact spot on Earth where they left 1985 would be up to 520.344 billion kilometers removed from the same location in space in 2015, give or take a few million kilometers (depending on the affects of the rotation of the planets and the solar system within the Milkyway)...which would put the DeLorean half way between Earth and Alpha Centauri. Well not really. Alpha Centauri is 41.32 trillion km from Earth but that's still pretty far from Hill Valley. Hopefully Doc packed some extra oxygen for the ride back! Great Scott!
