| | : Naw, you're thinking too much about this. Randall is just commenting that the universe, (as visible through the relatively small aperature of a windshield or mirror) is much bigger than it appears in either viewport. "There are more things in heaven and earth than are visible through your view-portal, Horatio!" (to paraphrase the Bard.) If that's what he was trying to say in Click and Drag, too, so be it. -- [[Special:Contributions/207.225.239.130|207.225.239.130]] 21:44, 24 October 2012 (UTC) | | : Naw, you're thinking too much about this.

| | I agree, I reckon it just means there is whole lot of universe out there that you can't see, regardless of what direction you're looking or what you're looking at it through.

| − | One thing confuses me: isn't the point that the scenery in the mirror is moving AWAY from the viewer - and hence would be red-shifted?? --[[User:Brahmafear|Brahmafear]] ([[User talk:Brahmafear|talk]]) 13:31, 25 October 2012 (UTC)

| − | :If he were moving quite fast, the scenery in the mirror '''WOULD''' be red-shifted. But since he's not moving very fast, he doesn't see the expected red-shift, and thus things look bluer than they normally would.--[[User:Joehammer79|Joehammer79]] ([[User talk:Joehammer79|talk]]) 14:54, 25 October 2012 (UTC)

| − | :That's a good question. He does appear to be in the passing lane (dashed lane to the right, unless he's driving on the wrong side of the road ;p but it wouldn't make sense to have a right-hand drive car with the warning on the driver side mirror), so he would ostensibly be going faster than slower traffic.

| − | :The scenery is red shifted and as such appears red, but is truly bluer than it currently appears in the mirror. This is just like the actual safety warning that the mirror makes things appear smaller (farther away) than if you were looking at them directly (I suspect this is to increase the field of view), so the objects are actually closer than they appear in the mirror. --[[User:Chexwarrior|Chexwarrior]] ([[User talk:Chexwarrior|talk]]) 20:38, 25 October 2012 (UTC)

| − | ::The passenger-side mirror on cars is slightly convex in order to increase the field of view (and hence decrease the size of the blind spot). The side effect of this is printed on the mirror.

| − | This comic has bothered me considerably. You'd need extreme speed to notice any doppler shifting of light, but you'd still get substantial color distortion from [http://en.wikipedia.org/wiki/Atmospheric_scattering Atmospheric Scattering], which causes far-away objects to turn ''blue''—so objects in the mirror are almost certainly less blue than they appear. --[[User:Tofudragon7|Tofudragon7]] ([[User talk:Tofudragon7|talk]]) 06:06, 9 November 2012 (UTC)

| − | The ACTUAL reason he says "Universe is larger than it appears" is because Edwin Hubble was part of the "Great Debate", which was a scientific conundrum in the early 20th century about whether the universe contained multiple galaxies or merely the Milky Way. Scientists were uncertain which theory was correct until Hubble's data, which conclusively showed, via observations of Cepheid variable stars, that galaxies such as Andromeda are located much too far away (about 2 million light years) to be located within our own galaxy. Consequently, the universe is much larger than it might originally appear to be.

| − | I thought the image text refers to space contraction when travelling at speeds close to the speed of light... Since the car moves, the driver sees the "rest of the universe", aka ouside, (barely) smaller than it really is. {{unsigned|178.192.228.170}}

| − | kinda strange warning, considering that the only objects behind you that you care about are usually those faster than you. maybe the sticker should read "beware of objects that are redder than they appear"? still a good one unless you think too much about it. i'd put one on my mirror anytime! --[[Special:Contributions/83.64.13.238|83.64.13.238]] 09:21, 10 December 2012 (UTC)

| − | Objects in the mirror are [younger, lighter, prettier] than they appear. (Because of light travel time, relativistic mass dilation, distance). [[User:Danshoham|Mountain Hikes]] ([[User talk:Danshoham|talk]]) 08:54, 24 February 2016 (UTC)

| − | :Aren't the objects than odler than they appear instead of younger? You see a x [timeunits] old item in the mirror, while when you see it it is x+(distance/c) [timeunits] old. with distance and c being larger than 0, the item is actually older than what you see. --[[User:Lupo|Lupo]] ([[User talk:Lupo|talk]]) 08:25, 22 October 2019 (UTC)

| − | Coming in very late, but physicist Randall is wrong. (At least, his mirror-engraver is wrong.) The objects in the mirror are not "bluer than they appear", because that statement implicitly privileges the ground's reference frame over the car's. The objects appear the way they appear, period. That's Einsteinian relativity's central lesson. If someone is on the same road, driving in the opposite direction, they see the objects as bluer than ''someone at rest with respect to the objects'', but neither of those reference frames is privileged over the mirror's.
