Getting to space is incredibly hard, expensive and needs a lot of resources.
A more efficient way to get there is a Skyhook (or Spacetether), an ever rotating cable with a counter weight, that catapults spaceships from earth orbit into the depths of space.

The Civil War Part 2: Crash Course US History #21 Teacherflix 3 Views • 2 years ago

In which John Green teaches you how the Civil War played a large part in making the United States the country that it is today. He covers some of the key ways in which Abraham Lincoln influenced the outcome of the war, and how the lack of foreign intervention also helped the Union win the war. John also covers the technology that made the Civil War different than previous wars. New weapons helped to influence the outcomes of battles, but photography influenced how the public at large perceived the war. In addition, John gets into the long-term effects of the war, including the federalization and unification of the United States. All this plus homesteading, land grant universities, railroads, federal currency, and taxes.

Check out the US National Archives Flickr. They have an awesome collection of Matthew Brady Civil War photography here: http://www.flickr.com/photos/u....snationalarchives/co

Song Lyrics:
The letter g has a "g" sound, like gummy, gulp, and goo.
Lots of words begin with g. I'll sing a few for you!

Turkeys all say gobble gobble!
Babies say goo goo!
Gorillas go ooh ooh ahh ahh!
Ghoulie ghosts will just say boo!

Gooey, gurgle, goopy, gushy—funny words that start with g!
Where would a word like giggle be without that goofy letter g?
Without that goofy letter g!

Goldie the goldfish and Gus the guppy
keep swimming to and fro.
When Gus gets going, Goldie goes
wherever Gus decides to go!

Gooey, gurgle, goopy, gushy—funny words that start with g!
Where would a word like giggle be without that goofy letter g?
Without that goofy letter g!

Now, Gary goes gallopin' in the rain.
Through mud puddles, Gary sloshes.
He keeps his feet from gettin' wet
when he wears his green galoshes!

Gooey, gurgle, goopy, gushy—funny words that start with g!
Where would a word like giggle be without that goofy letter g?

Gooey, gurgle, goopy, gushy—funny words that start with g!
Where would a word like giggle be without that goofy letter g?
Without that goofy letter g! Without that goofy letter g!

The letter that goes "g"! Uh, what was it again?
Letter g!

The Oort Cloud: Crash Course Astronomy #22 Teacherflix 5 Views • 2 years ago

Now that we’re done with the planets, asteroid belt, and comets, we’re heading to the outskirts of the solar system. Out past Neptune are vast reservoirs of icy bodies that can become comets if they get poked into the inner solar system. The Kuiper Belt is a donut shape aligned with the plane of the solar system; the scattered disk is more eccentric and is the source of short-period comets, and the Oort Cloud which surrounds the solar system out to great distances is the source of long-period comets. These bodies all probably formed closer to the Sun and got flung out to the solar system’s suburbs by gravitational interactions with the outer planets.
