Usain Bolt is the fastest human on record, with a foot speed
of almost 28 mph. The speed of sound is about 770 mph in dry air. The
circumference of the earth that we whip about on is about 25,000 miles. An
object that wants to leave earth must achieve escape velocity, around 25,000
mph. The speed of light in a vacuum is about 187,000 miles per SECOND.
According to relativity, this is the ultimate speed limit of this universe;
nothing can actually achieve it, except light.
The sun is 96 million miles from all us, which means that it
takes a ray of sunlight about 8 minutes to travel through space to poke you in
the eye on the drive home. A light year is actually a measure of distance, it
is the distance that light travels in a year, or 5.87849981 × 1012 miles.
Big number, huh?
But not really. In astronomy, distances are measured in
parsecs, equal to about 3.25 light-years, kiloparsecs, megaparsecs (1 million
parsecs) and gigaparsecs, which represent a billion.
Sounds like a lot of Han Solo talk, right? This is the basic
language needed to describe the largest scale structures of our home, this
universe - filaments, sheets and walls, formed by patterns in gigantic clusters
of BILLIONS OF GALAXIES, which are separated by mind-bogglingly immense voids,
creating a web or sponge-like structure...made of stars. We could reverse the process and visit the molecular, atomic and quantum worlds.
I went through all of that as sort of an exercise for all of
us to appreciate a few things. The first is the idea that structure and
symmetry exist on the most immense scales imaginable – look at some of the
images of the galactic superstructures, they are quite beautiful. The second
thing it brings to mind is the immensity of this place, this ever expanding
universe that we share, and the tremendous capacity for knowledge and
understanding we acquire through the instruments and techniques of reason. We
should never surrender the capacity for investigation and the right to question
traditional explanations.
We have the power to solve our problems. We have the capacity to understand them and
the power to resolve them. Perhaps we can look to our children for the wisdom
to not repeat them. But it is up to us to deal with those hostile, nihilistic
voices in our global community who do not seek solutions, those who profit from
problems and treat our one and only spaceship as their private property, with
no regard for progression of ancestors stretching behind us, nor the children
waiting to be born.
We all love Star Trek and Star Wars, right? Those incredible
programs that used the power of imagination to show us what is possible, to
show us ourselves among the stars….
I am telling you that we will never reach the stars until we
deal with the less evolved here on Earth. It is not okay to be hateful or cruel or
discriminatory because of outdated superstitious customs or ethnic vendettas. It
is not okay to own the earth and let many starve so that a traitorous few may
rule. It’s not okay to not evolve, to want to return to the image of a past
that never was. It's not okay to pretend corporations are people, or that people are disposable, or that the planet can be replaced.
Let’s proceed, instead, into the future, together…
