Why is it so dark?
- In the beginning, it is always dark
- What is that?
- One grain of sand
It is all that remains
Light is the elusive, mystifying form of energy
Although invisible by itself
Light reveals most of what we know about our surroundings
How can invisible energy make things visible?
When the sunlight shines through the blackness of space
It's black
But I was in the sunlight and I was able to look at this blackness
- I mean, what are you looking at?
- Call it the universe, but it's the infinity of space
The infinity of time
I'm looking at something called space that has no end
And at time, that has no meaning
Open your hand
What are you going to wish for?
A laser produces a very intense beam of light
