5 Advanced Space Drives (That May Or May Not Work) | Answers With Joe

1 Newton = force exerted against your hand by an apple. Well played, Joe.

Arthur C Clarke has one of my favorite quotes ever. “Either we are alone in the universe, or we aren’t. Both are equally terrifying.”

"Or maybe pursuing this is all just a waste of time" -- No. Not a waste of time. A caveman decided to sharpen a stick once and that, through a chain of extremely unlikely and fortunate (or unfortunate) events, we got to discussing making warp drives in the first place. A caveman is already convinced we possess magic. And space travel, and the pursuit of it, has lead to so many innovations in just one human lifetime that our own parents have trouble keeping up. The future is built on the backs of all of these, often stupid, often fruitless pursuits. Be it an idiotic dean drive, or the first five hundred things a caveman sharpened before realizing he could stab things with it. We're getting there. Give us time.

The electron drive: tests have been positive! * crickets *

"The Earth is a jealous mistress. One who does not give up easily its children."

Hi Joe, could you do a video on the possibility of life on Venus based on the presence of Phosphine?

"maybe a starship can drop it out on the way to the moon" best line I've heard in a long time

Clark had a fourth law, "For every expert there is an equal and opposite expert"

Hi Joe, Could you make a video on deep sleep, cryo sleep etc.

The XLS drive is my favourite. If you've ever been scrolling down an Excel spreadsheet and scrolled down too much you've no doubt seen extreme relativistic acceleration of the cursor. It goes fro Row 50 to like 5 million in a hundredth of a second! Harness that and we'll be on Risa in no time!

maybe we'll find a Stargate buried and skip the spacecraft.

"Exotic Matter" can be found in "Unobtainium"

"Maybe a different species..." 16:46 Neil Breen lol

Hey joe, love your show! Special request: would you do an update on the flint water crisis? What efforts, if any, are being made.

15:00 How many technologies that we use every day would have looked like a waste of time before some revolutionary discovery was made?

Hi Joe, in 20 years of listening to speakers (including myself) justify human piloted space exploration, I have never seen a better, more succinct argument than the one you made in a record 8 seconds. This video was a great snapshot of the field, and also very respectful of both the practitioners and the naysayers. Well done sir! PS Mr. Agnew is going to be thrilled to be featured here if he isn't already aware of the video. :)

"Wouldn't that be a small Hadron Collider" I'm pretty sure if you combine a "Small" and a "Large" you would get a Medium

My main complaint about Nebula is that there are no comments. Sometimes there are very interesting stories or discussions in the comments on YouTube.

One of my favorite ways to power ion drives in Kerbal Space Program was using a couple of radio-thermal generators to charge batteries, and doing a "short" burst using the ion thrusters when the batteries were charged. Recently, I was wondering about using Super Capacitors instead of batteries (for the high cycle count and low weight) ... and the concept of Diamond Batteries takes the power source to a whole new level.

As always...great content and the fun, Joe Scott, always makes it great to watch.
