Purpose of the Lightspeed Sector:
To encourage parents/kidlings/students to think about:
The Speed of Light The times and distances involved
How wondrous the Cosmos truly is
Relaying this wonderment to offspring/students/friends
The brevity of a human lifespan, or all of recorded history for that matter,
as compared to the timescale in GEOLOGY and ASTRONOMY For the time being, the ONLY way an average inhabitant of Earth can travel through the visible cosmos,
is with imagination, and as much $ as possible for a telescope!
We'll miss you, Jack...we're looking up!
Enjoy the Journey.....begin at 14 billion....then zoom in:
An Atlas of the Universe
Your current speed is 186,282 miles/sec.
That's about 670,000,000 miles per hour.
It takes you 1 second to circumnavigate the Earth 7 times.
You are 8.3 light minutes from the Sun.
You are 4.24 light years from the nearest star (other than our sun) - Proxima Centauri.
A Light Year is roughly 6 trillion miles.
You are about
30,000 Light Years from the center of your galaxy.
You live in an average size galaxy...roughly 100,000-120,000 Light Years in diameter.
Your neighbor spiral galaxy, m31 (Andromeda), is about 2.5 million lt. yrs. distant.
Here is a bit of history on lightspeed research:
Olaf Roemer made the first quantitative measurements of the speed of light.
Albert Abraham Michelson
Carl Sagan - Time Travel / LightSpeed
Approximate Time - Distance Reference:
Our Sun - 8.3 Minutes
Pluto - 5.3 Hours
Proxima Centauri (Closest Star, other than our Sun) - 4.24 Years.
Andromeda (M31 - Our
Sister Spiral Galaxy) - between 2.3 and 2.9 million Years.
An interesting note: "The modern values for Galactic rotation and heliocentric radial velocity
yield that the Andromeda Galaxy and the Milky Way are approaching each other at about 100 km/sec."
- Quote from the S.E.D.S. website...which seems to be no longer in existence....
Whirlpool Galaxy (M51) -
Depending on which measuring method is used, the distance is between 23 and 35 million light years.
Sombrero Galaxy (M104) in
the Virgo Cluster of Galaxies - a beautiful object about 28 million LtYrs away
