Great video. One day we will visit the binary star system of *Alpha Centauri.*

[@glennpearson9348]

Or, it will visit us...

[@xoqvuz]

Actually, Alpha Centauri is trinary/ternary star system.

[@goteverlastinglife]

Yeah, but it will be a long ride!!!

[@stylesrj]

Chances are we'll send a spaceship full of the best and brightest... then their Captain will be killed shortly before arriving and the colonists would be split between various factions... I think the only real choices would be the University or the Morgans...

You know on the Internet whatever data you put can never be removed. It will always be there. This means same thing in the universe. Whatever we do, say or whatever happens everywhere by even animals and trees and inner dimensions is being saved. The more I study science the more I believe that there really is a creator of all.

[@shanewilson7994]

I love seeing a video where I come in expecting to ask a question about it from just the Title, and my question get answered by the video instead. Question was going to be "can planets form in these systems, and if so, how bright would the other suns be." But kinda got the answer to that, but I do have one if you read this. So the Alpha Centari system is trinary. I know those stars are spaced out, but if there is a planet around, lets say Alpha Proxima at around the Earth's orbit, would it be affected by the gravity of the other two stars, or would they be so far out it would be negligible (kind of like Jupiter is to us).

The Great Year (narrated by James Earl Jones) makes a compelling case that our Sun is in a binary system with a yet to be detected mass such as a brown dwarf or black hole and suggests an orbiting Sun better explains the precession of the equinox than the lunisolar theory of a wobbling earth. Have you seen the documentary? Do you think it's a possibility?

[@mr.rousseau.4655]

What happens to the second binary star after the first one explodes?

[@danacollins2625]

Unary star systems are commonly referred to as "uncommon", but this is a bit misleading. Star systems with a single star comprise about _half_ of all star systems. Binary star systems comprise _about_ the other half. Meaning, one third of all stars are unary, and two thirds are binary. Trinary and quaternary star systems comprise a tiny percentage of the rest. So, star systems with a single star make up about 33% of all star systems. This might be _less_ common than stars in binary systems, but it is hardly "uncommon".

[@artkoenig9434]

Would the inverse square law only apply in the planetary motion around a single star?

I just wanted to write and say how much I've been enjoying your astronomy series. I'm 46 and, in truth, poorly educated. My knowledge of, and fascination with, astronomy is something that I have gleaned from various sources over the last 25 years or so but it is still very much a lay-person's level of understanding. Your series, being incredibly easy to digest, has filled in a lot of the gaps in that knowledge whilst being very entertaining. So, thank you Prof. Dave and keep up the good work.

[@zak6502]

What's the meaning behind all this phenomena? And most importantly why are we aware of it? Don't get me wrong it's very interesting and intriguing but at the same time, very confusing as of its ultimate meaning, and thinking that all this happens without any reason nor involvement of "something" or "someone" is just as absurd as its happening itself. Great video Mr Dave

There's no inherent meaning in the universe, create your own meaning.

Hey, Dave. A little over 5 months ago, I ran the numbers on a video of Team Skeptic's, a video involving Bruce Lipton. Bruce Lipton claimed a human has 70,000,000,000,000 volts inside their body, which can be "focused through training and meditation to be used for healing". ...let me rephrase that: "focused through training and meditation to be used for healing 3/4 of the Contiguous 48 into a glass floor". Could you make sure I didn't miss anything in translation along the way to the 1.2-petaton final result?

[@ProfessorDaveExplains]

Sounds like hogwash to me.

[@SahilYadav-ck4qe]

@@ProfessorDaveExplains i know right, that's absurd

[@Tornadopelt]

@@ProfessorDaveExplains I know, but I was running the numbers on a point Team Skeptic missed. Bruce claimed a human had 70 trillion volts that they could unleash at will. And I factored in two scenarios: a human with dry and unbroken skin, and a human with wet/broken skin. The former: 100 kilo-ohms. The latter: 1 kilo-ohm. As you probably already know, current (I) is voltage (V) divided by resistance (R). For the first human, I got 700 million amps, and for the second one, I got 70 billion amps. I then wanted to find the power the humans contained, using P = I * V (Power = Current * Voltage). First human: 4.9e+22 watts. Second human: *4.9e+24* watts.

[@xiaozhang7103]

Tornado In A Junkyard now you know how to apply formulas! Although the 70 trillion volts thing is... not a thing.

[@Tornadopelt]

@@xiaozhang7103 Mind you, Bruce Lipton MEANT 70 trillion... he did, however, say 700 trillion. Continuing onward... After I found out how many watts each person could generate, I converted to joules, since a joule is a wattsecond. To prevent numbers that went out of control, I assumed that this energy would be stored and released in one second. So, the first human has an energy of 4.9e+22 joules, and the second human has an energy of 4.9e+24 joules. But it gets worse, because I then converted the joules into kilotons of TNT. First human's yield: about 12 billion kilotons (12 teratons). Second human's yield: About 1.2 TRILLION kilotons (1.2 *petatons).* I then plugged those numbers into Nukemap Classic. Both shots were centered on St. Louis. The first blast reached out to Davenport, Iowa. The *second* blast reached out to Phoenix, Arizona.
