Time is a River

---

In Einstein's equation, time is a river. It speeds up, meanders, and slows down. The new wrinkle is that it can have whirlpools and fork into two rivers. So, if the river of time can be bent into a pretzel, create whirlpools and fork into two rivers, then time travel cannot be ruled out. -Michio Kaku

The concept of time as a river fascinates me. The topic of time travel has always interested me. I loved seeing it in tv shows like Star Trek and Timeless. The Time Machine and Back to the Future were classic time travel flicks. Going back, and going forward, in time is simply a fascinating concept. Here are a few timely quotes. ツ

Time travel offends our sense of cause and effect - but maybe the universe doesn't insist on cause and effect. Edward M. Lerner

I distracted myself from the fear and terrorism by thinking about things like how the universe began and whether time travel is possible. -Malala Yousafzai

'Closed timelike curve' is the jargon for time travel. It means you go out, come back and meet yourself in the past. -Kip Thorne

The bottom line is that time travel is allowed by the laws of physics. -Brian Greene

Time travel used to be thought of as just science fiction, but Einstein's general theory of relativity allows for the possibility that we could warp space-time so much that you could go off in a rocket and return before you set out. -Stephen Hawking

“If time travel is possible, where are the tourists from the future?” -Stephen Hawking, A Brief History of Time
