SETI's Quiet Skies

The universe is immense.
The nearest star is 4 light years away - 8 years for an answer to hello at the speed of light.
Tens of thousands of years of travel to.
And that our nearest neighbor.

There are 200 billion stars in our galaxy some 100,000 light years across - the distance light, traveling at 186,000 miles/second, travels in 100,000 years.

There are at least 1200 billion galaxies in our universe, millions, even billions of light years away.
The speed of light then too slow for meaningful interstellar communication or travel.

But the speed of light is as fast as anything can travel. Are we then to be imprisoned by time and distance to just this tiny speck of a solar system while nearly everything there is remains forever out of our reach?

No

Then, what?

We will find a way. Intelligence always finds a way.

And when we do prepare to meet the intelligent universe.
