When neurons communicate, an electrical impulse triggers the release of neurotransmitters from the axon into the synapse. The neurotransmitters cross the synapse and bind to special molecules on the other side, called receptors. Receptors are located on the dendrites. Receptors receive and process the message.

A nerve signal travels from your eye to your brain then to your finger muscles. Your finger muscles move to catch the timer. The whole process takes between 150 and 220 milliseconds. The neural pathway involved in a reaction time experiment involves a series of neural processes.

1) Fast forms of synaptic transmission last from about 10-100 msec, -at most CNS synapses are mediated by 2 categories: the amino acids: —>glutamate (Glu), gamma-aminobutyric acid (GABA) , or glycine (Gly) .

Learning fast or being a quick learner depends on how we use our brains. Sometimes what seem so sophisticated needs the simplest solution….13 Signs You’re A Pretty Quick Learner

1. You are not afraid to say “I don’t know”
2. You use the Pareto principle.
3. You are able to visualize it.
4. You simplify.
5. You take action.

The smarter the person, the faster information zips around the brain, a UCLA study finds. And this ability to think quickly apparently is inherited. The study, published in the Journal of Neuroscience, looked at the brains and intelligence of 92 people.

Using this, Psychologists recently found an estimate of around 60 bits per second for the maximum processing speed of the human brain. Others have established that everyone’s brain has a similar processing speed, although those with a higher IQ are slightly faster (E. Roth (1964)).

Is 20 mph Fast For a Human? Yes, If you run the entire hundred metres in 20mph, you will get a time of 11.1 seconds.

“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 .”

“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”.

But Einstein showed that the universe does, in fact, have a speed limit: the speed of light in a vacuum (that is, empty space). Nothing can travel faster than 300,000 kilometers per second (186,000 miles per second).

About the Author

• Cheetahs are the world’s fastest land animal, capable of reaching speeds of up to 70 mph.
• In short, cheetahs are built for speed, grace, and hunting.
• Cheetahs mainly prey on small antelopes such as Thomson’s gazelles and impalas, although they will also hunt small mammals and birds.

The greater the mass of an object, the more powerful the effect. The huge mass of a black hole produces a gravitational “sink” from which not even light can escape. No, black holes cannot travel faster than light.

Q: Which object travels faster than light? The controversial hypothetical particles Tachyons are said to travel faster than light. However, according to Einstein’s special theory of relativity particles regarding speed of light, they can never travel faster than light in the real world.

The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light. In miles per hour, light speed is, well, a lot: about 670,616,629 mph. If you could travel at the speed of light, you could go around the Earth 7.5 times in one second.

Black holes are regions of space-time where gravity rules: The gravitational pull of a black hole is so strong that nothing, not even light, can escape. But even the black holes will one day die.

Yes, It’s Possible to Safely Jump Into a Black Hole. But if you’re going to try it, you need to know this one small catch. Scientists say humans could indeed enter a black hole to study it. Of course, the human in question couldn’t report their findings—or ever come back.

A black hole is a tremendous amount of matter crammed into a very small — in fact, zero — amount of space. The result is a powerful gravitational pull, from which not even light can escape — and, therefore, we have no information or insight as to what life is like inside.

There Are at Least 4 Ways a Black Hole Could Kill You

• Spaghettification. Black holes form when a massive object, like a star, collapses and squeezes all of its mass into an impossibly small point with infinite density, known as a singularity.
• Fried by Accretion Disk.
• Zapped by Plasma Jet.
• Incinerated by Firewall.

If you jumped into the black hole feet first, the gravitational force on your toes would be much stronger than that pulling on your head. Each bit of your body would also be elongated in a slightly different direction. You would literally end up looking like a piece of spaghetti.

If a black hole were to form from the Earth itself, it would create an event horizon just 1.7 centimeters in diameter. Eventually, some time later, any object at rest — no matter how far away from the event horizon it initially was — will cross that horizon and encounter the central singularity.

Wormholes are shortcuts in spacetime, popular with science fiction authors and movie directors. They’ve never been seen, but according to Einstein’s general theory of relativity, they might exist.

While the mind-bending physics of quantum mechanics—the physics of the very small—allow for this so-called negative energy, it is hard to have a sufficient amount to make a traversable wormhole possible.

As for backward time travel, it is possible to find solutions in general relativity that allow for it, such as a rotating black hole. Traveling to an arbitrary point in spacetime has very limited support in theoretical physics, and is usually connected only with quantum mechanics or wormholes.

The Short Answer: Although humans can’t hop into a time machine and go back in time, we do know that clocks on airplanes and satellites travel at a different speed than those on Earth. We all travel in time! We travel one year in time between birthdays, for example.
