The current speed record has stood for 46 years. Those jets would carry no crew – but not because humans can’t travel at such high speeds. In fact, humans have already travelled many times faster than Mach 5.

Most of us can withstand up to 4-6G. Fighter pilots can manage up to about 9G for a second or two. But sustained G-forces of even 6G would be fatal.

Our bodies are surprisingly resilient in many situations, but rapid acceleration is not one of them. While the human body can withstand any constant speed—be it 20 miles per hour or 20 billion miles per hour—we can only change that rate of travel relatively slowly.

If human manoeuvre that speed Mach 1(1225 Kph), the air friction will increase the body temperature enormously. It will almost boil the body. The strange symptoms including temporary vision loss, loss of consciousness and weightlessness. The turbulence causes parts of the body swell out.

“The NHTSA standard for a sudden impact acceleration on a human that would cause severe injury or death is 75 g’s for a “50th percentile male”, 65 g’s for a “50th percentile female”, and 50 g’s for a “50th percentile child”.

Shadows. In principle, shadows can move faster than the speed of light. When a shadow is bigger than the object casting it, it moves at a greater distance but in the same amount of time. If the shadow is large enough, it could move across the surface faster than light.

Black has a wide range of associations. It can be linked with death, mourning, evil magic, and darkness, but it can also symbolize elegance, wealth, restraint, and power.

Black is a color which results from the absence or complete absorption of visible light. It is an achromatic color, without hue, like white and gray. It is often used symbolically or figuratively to represent darkness.

Darkness, the polar opposite of brightness, is understood as a lack of illumination or an absence of visible light. Referring to a time of day, complete darkness occurs when the Sun is more than 18° below the horizon, without the effects of twilight on the night sky.

Eigengrau (German for “intrinsic gray”; pronounced [ˈʔaɪ̯gŋ̍ˌgʁaʊ̯]), also called Eigenlicht (Dutch and German for “intrinsic light”), dark light, or brain gray, is the uniform dark gray background that many people report seeing in the absence of light.

Definitions of total darkness. total absence of light. “they fumbled around in total darkness” synonyms: black, blackness, lightlessness, pitch blackness. type of: dark, darkness.

Shadow the hedgehog runs at a speed of 299,338 kilometers per second. This translates to almost exactly 186,000 miles per second. This is significantly faster than Sonic the Hedgehog’s ability to run 3,840 miles per second.

The Flash is faster than Sonic. Sonic the hedgehog runs at the speed of sound. While the Flash can run so fast he can jump through time. The Flash because Sonic can’t break the sound barrier and bend time.

Shadow is stronger and Sonic is faster. They have fought many times although in Shadow the Hedgehog (game), Shadow can kill Sonic. And Sonic has beaten Shadow a few times as well.

Sonic

As an antihero, Shadow has good intentions but will do whatever it takes to accomplish his goals, putting him at odds with series protagonist Sonic the Hedgehog. Shadow shares many attributes with Sonic and thus controls similarly in games, but is distinguished by his uses of vehicles and firearms.

Top 10 Fastest “Sonic the Hedgehog” Characters

• Espio the Chameleon.
• Silver the Hedgehog.
• Miles “Tails” Prower.
• Blaze the Cat.
• Emerl.
• Infinite.
• Scourge the Hedgehog.
• Shadow the Hedgehog.

However, she has admitted that she is not as fast as Sonic. Amy likewise has impressive durability, being able to go through atmospheric reentry and then land on the ground unharmed. Amy creating a tornado with her hammer, from Sonic Heroes.

When in flight, Tails can move at incredible speeds, reaching that of 768 Mph, and can even go fast enough to keep up with Sonic. This makes Tails one of the fastest characters in the series, right behind, or even at the same speed as Sonic.

Goku was faster than lightning as a kid and faster than light around Namek. Sonic clocks around low mach speeds with Super around light speed, he would appear frozen compared to Goku. Archie Sonic on the other hand is faster than Goku and is the only Sonic put up a fight against him and probably win.
