Tolkien and Time Travel

Did you know Tolkien started a story about time travel? That's the subject of this video, which also touches on C.S. Lewis' Space Trilogy. I didn't mention the name, but the story he started is called The Lost Road, and can be found in Volume 5 of the History of Middle Earth series, here: https://www.amazon.com/Lost-Other-Writings-History-Middle-Earth/dp/0345406850/ref=sr_1_1?s=books&ie=UTF8&qid=1475409102&sr=1-1&keywords=the+lost+road+and+other+writings. Lewis' Space Trilogy can be found here: https://www.amazon.com/Trilogy-Silent-Perelandra-Hideous-Strength/dp/1451664826/ref=sr_1_2?s=books&ie=UTF8&qid=1475409389&sr=1-2&keywords=c.s.+lewis+space+trilogy. Apologies for the quality of the video; I had this rough cut ready and was trying to polish up something else, but life got in the way and I wanted to have something new early this week because I won't be able to publish again for a while.
