►Is faster-than-light (FTL) travel possible? In most discussions of this, we get hung up on the physics of particular ideas, such as wormholes or warp drives. But today, we take a more zoomed out approach that addresses all FTL propulsion — as well as FTL messaging. Because it turns out that they all allow for time travel. Join us today as we explore why this is so and the profound consequences that ensue. Special thanks to Prof Matt.

Wormhole vs Black hole? Which one do you prefer? Most importantly which one truly exists?
Why don’t you watch this video and find out because the information will shock you! Today you’ll FINALLY find out if you can in reality TIME TRAVEL!
So spread the video to pass the word.
Wondering what would happen if you fell into a Black hole? How about if the whole universe got sucked into it? Scary but you’ll get the answers in this video as well.
Enough said. Black hole conversations can be pretty dark.
So do like, share and subscribe to our channel Because it’s Interesting!
From the cosmic microwave background to Feynman diagrams — what are the underlying rules that work to create patterns of action, force and consequence that make up our universe?
Brian’s new book “Ten Patterns That Explain the Universe” is available now: https://geni.us/clegg.
Watch the Q&A: https://youtu.be/RZB95znAGRE
Brian Clegg will explore the phenomena that make up the very fabric of our world by examining ten essential sequenced systems. From diagrams that show the deep relationships between space and time to the quantum behaviours that rule the way that matter and light interact, Brian will show how these patterns provide a unique view of the physical world and its fundamental workings.
Brian Clegg was born in Rochdale, Lancashire, UK, and attended the Manchester Grammar School, then read Natural Sciences (specialising in experimental physics) at Cambridge University. After graduating, he spent a year at Lancaster University where he gained a second MA in Operational Research, a discipline developed during the Second World War to apply mathematics and probability to warfare and since widely applied to business problem solving. Brian now concentrates on writing popular science books, with topics ranging from infinity to ‘how to build a time machine.’ He has also written regular columns, features and reviews for numerous magazines and newspapers, including Nature, BBC Focus, BBC History, Good Housekeeping, The Times, The Observer, Playboy, The Wall Street Journal and Physics World.
This talk was recorded on 28 September 2021.

This is a bit dated, but some famous scientists in here with really good info.; a must watch for those with interest in science based time travel.
Dr. David Deutsch discusses time-travel theories.
Antenna BBC 1992
A man, named John Titor, in 1998 claimed that he arrived from the year 2034. He described his time travel in great detail and vanished!
“PARADOX LOST: The Public Edition, by Marshall Barnes,” Oct 6, 2014.
This book is by internationally noted research and development engineer, Marshall Barnes, and is based on his special report for select members of the United States Congress on the coming reality of time travel, which is now here on the particle level. The only authoritative book on the subject of time travel, it scientifically answers all the issues around the topic, proves why paradoxes are impossible and why the world’s physicists have been so wrong about time travel for so long. Includes definitive analysis of errors by Stephen Hawking, Kip Thorne, Paul Davies, Tim Maudlin, among others. Answers Kurt Godel’s famous question of how can a past that hasn’t passed yet, be the past, and many other issues left unanswered by all other sources.
Among outstanding features, it details Marshall’s creation of the Verdrehung Fan™, the first time machine in the world, that is sending signals through traversable micro wormholes, as speculated could be possible in New Scientist magazine, May 20th, 2014. The Einstein related physics from which it works and how Marshall used it to defeat world famous Ronald Mallett in the race to build a time machine, is revealed as well as why Mallett is far less than the media has made him seem.
Easy to read but rich in detail, this book will be a challenge for scientist and non-scientist alike, with preconceived notions about the subject, as all cliches are dismantled and discarded, revealing stunning, hidden truths that are reached without ever taking a step off the path of known physics. This is the book for those wanting definitive answers backed by definitive proofs and calculations, without dealing with the heavy mathematics.
This paper discusses the quantum mechanics of closed timelike curves (CTC) and of other potential methods for time travel. We analyze a specific proposal for such quantum time travel, the quantum description of CTCs based on post-selected teleportation (P-CTCs). We compare the theory of P-CTCs to previously proposed quantum theories of time travel: the theory is physically inequivalent to Deutsch’s theory of CTCs, but it is consistent with path-integral approaches (which are the best suited for analyzing quantum field theory in curved spacetime). We derive the dynamical equations that a chronology-respecting system interacting with a CTC will experience. We discuss the possibility of time travel in the absence of general relativistic closed timelike curves, and investigate the implications of P-CTCs for enhancing the power of computation.
Look past the details of a wonky discovery by a group of California scientists — that a quantum state is now observable with the human eye — and consider its implications: Time travel may be feasible. Doc Brown would be proud.
The strange discovery by quantum physicists at the University of California Santa Barbara means that an object you can see in front of you may exist simultaneously in a parallel universe — a multi-state condition that has scientists theorizing that traveling through time may be much more than just the plaything of science fiction writers.
And it’s all because of a tiny bit of metal — a “paddle” about the width of a human hair, an item that is incredibly small but still something you can see with the naked eye.
