In this video we answer the question “What is time?” We tackle this both conceptually and mathematically to demonstrate that time or “c” is a physical geometric side to the containing space of the Universe.

At the end of the video, we also dive into how this approach will make it easier to travel faster than light (FTL), understanding black holes, and what anti-gravity really is.

Keep in mind, this is CHAPTER 5. You can see the whole playlist here:

*note: In the video I joked about “killing the multi-verse” – just to clarify, this is A multiverse. There are other ideas of a multiverse I didn’t cover. But, they are on my hit list for later on.

Here are videos of “Real Scientists” telling you what they think time is:

As a note, obviously we are all playing around with the same “Minkowski Spacetime” here. This just goes to show how much of a difference interpretation makes and how little an equation alone really communicates.

Here is the article from Big Think talking about how scientists eschew anything that calls the Big Bang into question. Don’t skim it, slow down and read between the lines: https://bigthink.com/starts-with-a-ba...

Here is a link to the 1+3 (1 space + 3 time) paper I reference:

For those who have asked, I started working on companion articles for this series to complement the videos. You can follow the series on Medium.com here:   / christhebrain   – While they will largely cover the same content, I am “filling in gaps” and will dive into more math in them as I go.

Finally, my daughter has a stand-alone version of the “Mach’s Principle” animation you can see here:
