00:00:01,920 --> 00:00:06,600
Speaker 1: Welcome to brain Stuff production of I Heart Radio, Hey

2
00:00:06,640 --> 00:00:10,280
Speaker 1: brain Stuff, Lauren bog Obam Here. When it comes to

3
00:00:10,440 --> 00:00:13,920
Speaker 1: fictional animals capable of breaking the sound barrier, there's no

4
00:00:14,080 --> 00:00:17,119
Speaker 1: beating Sonic the hedgehog. But would he be able to

5
00:00:17,160 --> 00:00:21,279
Speaker 1: survive his own super swiftness. Sonic is the star of

6
00:00:21,320 --> 00:00:23,799
Speaker 1: the long running Sega video game franchise and now a

7
00:00:23,840 --> 00:00:27,040
Speaker 1: movie wherein he spins and rolls at breakneck speeds in

8
00:00:27,120 --> 00:00:30,560
Speaker 1: order to defeat the evil doctor robot Nick. So how

9
00:00:30,640 --> 00:00:34,280
Speaker 1: fast do Sonic go? As his name implies, he reaches

10
00:00:34,360 --> 00:00:37,080
Speaker 1: sonic speeds, meaning that he can travel as fast as

11
00:00:37,080 --> 00:00:40,320
Speaker 1: a sound wave through Earth's atmosphere, which is roughly seven

12
00:00:40,400 --> 00:00:43,080
Speaker 1: hundred and sixty seven miles per hour or one thousand,

13
00:00:43,159 --> 00:00:46,000
Speaker 1: two hundred and thirty five kilometers per hour depending on

14
00:00:46,040 --> 00:00:51,280
Speaker 1: air temperature. He also goes supersonic under the right circumstances,

15
00:00:51,320 --> 00:00:53,560
Speaker 1: so it's probably safe to assume that he exceeds the

16
00:00:53,600 --> 00:00:59,080
Speaker 1: speed of sound as well. That's incredibly fast. Most hedgehogs

17
00:00:59,120 --> 00:01:01,840
Speaker 1: do get around. They're extremely active in the wild and

18
00:01:01,880 --> 00:01:05,040
Speaker 1: often run several miles each night, which are regular hedgehog

19
00:01:05,080 --> 00:01:09,920
Speaker 1: business hours, but sonic speeds are much faster. Consider that

20
00:01:09,959 --> 00:01:13,360
Speaker 1: the world's fastest organism, the Peregrine falcon, only reaches a

21
00:01:13,360 --> 00:01:16,000
Speaker 1: maximum speed of about two hundred miles per hour or

22
00:01:16,120 --> 00:01:21,240
Speaker 1: three kilometers first sustained speeds. The Cheetah is Sonic's closest rival,

23
00:01:21,360 --> 00:01:23,800
Speaker 1: at a mere seventy miles per hour or a d

24
00:01:24,000 --> 00:01:30,000
Speaker 1: ten kilometers. Sonic smokes them both. So could Sonic realistically

25
00:01:30,080 --> 00:01:34,880
Speaker 1: handle supersonic speeds. Let's think about it. Humans routinely break

26
00:01:34,920 --> 00:01:39,319
Speaker 1: the sound barrier in supersonic aircraft. Aboard the now discontinued Concorde,

27
00:01:39,319 --> 00:01:42,720
Speaker 1: passengers could even enjoy an in flight meal. But this

28
00:01:42,800 --> 00:01:46,080
Speaker 1: is all within the artificial confines of an airplane. All

29
00:01:46,080 --> 00:01:49,760
Speaker 1: Sonic has is his own body. His body would have

30
00:01:49,840 --> 00:01:53,120
Speaker 1: to be incredibly strong and durable to achieve and survive

31
00:01:53,240 --> 00:01:56,480
Speaker 1: the wear and tear of supersonic speeds, even if he's

32
00:01:56,560 --> 00:01:59,760
Speaker 1: rolling through smooth tubes and shoots half the time at

33
00:01:59,760 --> 00:02:02,360
Speaker 1: those speeds, small particles of dust and even the air

34
00:02:02,360 --> 00:02:06,880
Speaker 1: itself could cause serious damage. As author James Cacallios points

35
00:02:06,880 --> 00:02:10,079
Speaker 1: out in the Physics of Superheroes, a super fast organism

36
00:02:10,120 --> 00:02:13,640
Speaker 1: like the Flash would need superhaling abilities to rapidly recover

37
00:02:13,680 --> 00:02:16,920
Speaker 1: from the physical damage of each acceleration, to say nothing

38
00:02:16,960 --> 00:02:21,160
Speaker 1: of smashing into things. The same goes for sonic. But

39
00:02:21,200 --> 00:02:24,240
Speaker 1: then again, if we're to assume that sonic species evolved

40
00:02:24,280 --> 00:02:27,120
Speaker 1: to reach such high speeds, he must be sturdy enough

41
00:02:27,160 --> 00:02:29,720
Speaker 1: to survive it, at least in the short term. So

42
00:02:29,800 --> 00:02:32,000
Speaker 1: perhaps he does have the sort of enhanced healing speeds

43
00:02:32,000 --> 00:02:35,000
Speaker 1: necessary to keep all his bones and ligaments from snapping.

44
00:02:36,280 --> 00:02:40,000
Speaker 1: As pointed out by Duke Universities patech Labs, various animals

45
00:02:40,000 --> 00:02:42,560
Speaker 1: are capable of incredible speeds when it comes to parts

46
00:02:42,600 --> 00:02:46,000
Speaker 1: of their anatomy, such as the mantis shrimps three millisecond

47
00:02:46,080 --> 00:02:50,200
Speaker 1: club strikes. There's even a hypothesis that prehistoric sauropods could

48
00:02:50,240 --> 00:02:52,880
Speaker 1: have whipped their tails at sonic speed like a bull whip,

49
00:02:53,240 --> 00:02:57,519
Speaker 1: but that remains rather controversial, and maybe we're being too

50
00:02:57,520 --> 00:03:00,600
Speaker 1: hard on sonic. He's a blue hedgehog that chases coins

51
00:03:00,639 --> 00:03:04,200
Speaker 1: across a pinball landscape and in later games achieves faster

52
00:03:04,280 --> 00:03:07,360
Speaker 1: than light travel. Plus he's still going strong after almost

53
00:03:07,400 --> 00:03:10,400
Speaker 1: thirty years, which for a hedgehog is almost as impressive

54
00:03:10,440 --> 00:03:17,799
Speaker 1: as that speed. Today's episode was written by Robert Lamb
