I guess the "G L I D E" could be a reference to Fight Club scene. The one with the Penguin during one of Tylor's support groups. 09:03, 2 June 2014 (UTC) >In Fight Club, it's "Slide", though. 09:54, 8 June 2014 (UTC)

The statement someone added, saying that if gravity had ceased he'd leave the earth's orbit due to the lack of the Sun's gravity, is incorrect; the Sun's gravitational force at the Earth is far lower than the Earth's gravity, so the loss would not be noticeable until well after he'd ended up in space. As such, I removed that statement. (talk) (please sign your comments with ~~~~)

I have always wondered why flying/gliding dreams seem to be universal for humans, not to mention all those dreams where you are viewing the world from an elevated position, I.e. near the ceiling or up in a cloud. After all, people do not fly, none of us have ever flown, none of our ancestors have ever flown, so whence all these flying dreams? Not sure if our arboreal ancestors were ever nimble enough to "fly" through the trees, but it would have been a long way back. 12:24, 2 June 2014 (UTC)

In the last century a lot of us have flown (assisted). Of course, our obsession with the idea of flying is much older than our actual taking to the skies, by several millennia. (Unless, "Aliens!") But, could it simply be because all that there was to see at night was the sky? If you woke up in the middle of the night, stared at the stars for a few minutes and went back to sleep, would that make you want to travel upwards towards them in your dreams? 05:51, 3 June 2014 (UTC)
Our ancestors may not be able to fly, but they certainly known a lot about elevated positions. They might envied the birds for long time. -- Hkmaly (talk) 10:31, 4 June 2014 (UTC)
One thing that is certainly common and more likely is that under stressful or instructive periods in our lives, the release of tensions can lead to the impression of a cessation of sensation giving the intuitive impression of supernaturally elevated flight. This generally coincides with youthful experiences leading to increased perception of reality effectively elevating the individual's intelligence over their environment and the subconscious relates the relevance of these experiences with the very personal impression of a temporary separation from the cares. The landscape stays as a very strong presence reminding us that we remain a significant part of the social scene with responsibilities to it (effected by the ability to manoeuvre amongst and around other scenery in the dream), and should the subconscious have the opportunity, there will be recognisable references to the dreamer's conscious life as part of the dreamer's reminder to remain connected. This also presents a more peaceful way to interpret and learn from life and it's occurence should be encouraged to happen as early as possible in life. Dreams and educational dream interpretation are essential to maintaining a balance between our individual empirical past and present. Raydleemsc (talk) 04:47, 14 May 2015 (UTC)

Why is "GLIDE" in all-caps in the transcript? The whole comic is in all-caps. 12:32, 2 June 2014 (UTC)

perhaps because the letters are separated out(?)... it would look a little weird to me for them not to be all caps - all XKCD comics are in all caps (it's the font), so that's not a differentiating factor -- Brettpeirce (talk) 13:11, 2 June 2014 (UTC)
Correct - since it is not a single word but individual words they should all be capital. All sentences here in the transcripts are written with capital letters - so as these letters each represents an individual sentence they should begin with a capital letter. Kynde (talk) 13:54, 2 June 2014 (UTC)
I now disagree with my self. This is a single word just written with bad kerning. So it should be written G l i d e. Also Jump should be capital. --Kynde (talk) 23:54, 22 March 2016 (UTC)

It's a dream of every wolfenstein enemy-territory player ;-) Theres a bug where you can get a lot of speed be running and jumping around. 15:02, 2 June 2014 (UTC)

If Cueball isn't following the Earth's curvature, he could end up in Valinor (if he's travelling westward). —TobyBartels (talk) 19:59, 2 June 2014 (UTC)

I'm not sure what's happening at the "Recent Changes" link in the left sidebar, but it stalls halfway thru loading and then locks up 105% of my Mac's CPU. Could it be a super super long amount of data, and the sysops need to snip that to a more manageable level? Jimmbo (talk) 20:22, 2 June 2014 (UTC)

Is it relevant to talk about Newton's ludicrously high mountain experiment (>1000 km) => 7300 m/s? Why not simply state that you have to go around 7900 m/s at sea level to maintain orbit (if no other forces are acting on you) 21:30, 3 June 2014 (UTC)

Everybody knows that this slow gliding would only work in a dream. The correct speed at sea level would be 7.91 km/s and this comic isn't talking about this high velocities anyway. --Dgbrt (talk) 22:22, 3 June 2014 (UTC)
True enough 10:11, 4 June 2014 (UTC)
Yes it makes no sence and has nothing to do with the explain - so I have deleted the paragraph. Kynde (talk) 20:24, 9 June 2014 (UTC)

There are similarities to the story of flying Robert , a story from "der Struwwelpeter", german classic for children. 07:08, 4 June 2014 (UTC)

I used to have trouble landing the first few times too, but I got better soon. 09:47, 4 June 2014 (UTC)

A minor thing, but I think that "...unless one considers the possibility that Cueball's 'gliding' will continue in a straight line in relation to the Earth's surface." would be better re-written using the term "tangent". And would help later on in the explanation (regarding the Earth's surface bending away, etc). 02:29, 5 June 2014 (UTC)

PS, for the record my "flying dreams" are different, being more the "feet pressing/thrusting against the air" kind, trajectory controllable by leaning backwards and forwards, as if on an 'invisible airworthy Segway', and altitude by using more or less 'push'. Well, it makes sense to me when I'm dreaming, when I'm quite adept at it. 02:35, 5 June 2014 (UTC)

FTR, the first slide immediately reminded me of "Muž, který dovedl lítat" (The Man Who Knew How To Fly) by Karel Čapek (1938). Just go DuckDuck (or Google if you prefer), there are even (at least) two animated cartoons inspired by that. --kavol, 07:53, 5 June 2014 (UTC)

Anyone else notice that the hover text given in this xkcd's info.0.json is actually slightly different from the actual hover text? 19:51, 8 May 2016 (UTC)

This is actually a great, concise tutorial for flying in dreams. Practice jumping and not landing, and then you can invent skills to speed up, change direction, phase through solid objects, or add more style. Have fun with it and get inspired! Cueball will be fine. He's levitating at a set height above the terrain that slightly increases with his speed. If he thinks too much about how this works, he'll doubt himself and fall in the water. Also, happy 16th anniversary, xkcd! Hitstun (talk) 22:41, 30 September 2021 (UTC)
