Name: FTL02 - Tachyons And Time Travel by Isaac Arthur
Duration: 17 min 46 s
Description: Our second installment of a new series looking at Faster Than Light, or FTL, concepts and technologies. In this episode we look at the Tachyon, a hypothetical superluminal particle than can travel back in time as well as looking at what theory tells us about Time Travel and Temporal Paradoxes.

A series looking at concepts for truly huge structures that we might see in the future. This is an audio-only compilation of videos created originally for Youtube, and is best watched rather than listened to, the video playlist can be found at:

MS10 Matrioshka Brains

MS09 Nicoll - Dyson Beams

In Episode 4 we look at the concept of wormholes, how they derive from General Relativity, the various different types and theories, and some under-considered uses of wormholes. We'll also discuss some myths and misunderstandings of the concept.

FTL04 - Wormholes

In Episode 3 we look at the concept of warp drives, a theoretical type of spaceship propulsion that warps spacetime to allow faster than light travel. We discuss the basic concept and the scientific and technological hurdles to developing it, along with clearing up many of the myths about it.

FTL03 - Alcubierre Drive

Our second installment of a new series looking at Faster Than Light, or FTL, concepts and technologies. In this episode we look at the Tachyon, a hypothetical superluminal particle than can travel back in time as well as looking at what theory tells us about Time Travel and Temporal Paradoxes.

FTL02 - Tachyons And Time Travel

Our first installment of a new series looking at Faster Than Light, or FTL, concepts and technologies. In this episode we review the basics of Special Relativity and some misconceptions about it, then look at Quantum Entanglement.

FTL01 - Quantum Entanglement

Episode 5 of the Habitable Planets Series takes a look at double planets and what sort of conditions would prevail, or need to prevail, for them to be Earth-like. As well as the Rocheworld, a special case of Double Planets where the two planets either share an atmosphere or have even begun to merge together.

Note: make sure to set units of both bodies to Earth Mass and period to hours or days if trying to look at double planet cases.

HP05 - Double Planets And Rocheworlds

By contemplating the idea of what true Kardashev 2 and 3 civilizations might look like, in the context of Megastructures, we re-assess the Fermi Paradox and come up with a new question, no longer "Why can't we see any alien civilizations?" but why we can see any stars in the night sky at all.

FP02 - Dyson Dilemma

A look at the Carter Doomsday Argument, which is uses a probabilistic argument and Anthropic Reasoning to estimate that humanity is running out of time.

EC03 The Doomsday Argument

An in-depth survey of the various technologies for spaceship propulsion, both from those we can expect to see in a few years and those at the edge of theoretical science. We'll break them down to basics and familiarize ourselves with the concepts.
Note: I made a rather large math error about the Force per Power the EmDrive exerts at 32:10, initial tentative results for thrust are a good deal higher than I calculated compared to a flashlight

The Spaceship Propulsion Compendium

This episode begins a three-part series focusing more on the specifics of colonization including human aspect of it. We lay the groundwork by looking at colonies just in our solar system before moving off in episodes two and three to look at life on colony ships and then on interstellar colonies.
