Einstein said the fastest speed of light in the universe, but the existence of two phenomena have exceeded the speed of light

In Einstein's special theory of relativity that the speed of light in the universe 300,000km per second is constant. The speed of any kind of object is impossible to exceed the speed of light. So the speed of light has always been considered by scientists as the limit in the universe.

So in our world, is there any kind of object whose speed can exceed the speed of light?

Hello, today we are going to talk about the speed in the universe, and together we will reveal whether the object that exceeds the speed of light exists. If it exists, does such an object violate the traditional laws of physics?

Or the usual rules pointing attention to the arrangement, we start today's topic.

The growth rate of human fingernails, and toenails are about 1mm per month.

If you follow this speed to run a 100-meter track, then the time from the beginning to the end takes about 8000 years or so.

The otter is known as the laziest animal in the animal kingdom. It moves very slowly, so the origin of its name, some people may think, but also with its character has a certain relationship, the tree otter moves about two meters per minute, converted into the speed, it is about 0.12km per hour.

Because of its slow movement, it often faces threats from a variety of predators in nature. Long-term only live in the trees to avoid being captured by other animals, only when they want to defecate, do they climb from the trees to the ground, and reaching the ground they are at this moment is also the most dangerous time in their lives.

The normal walking speed of an adult is about four kilometers per hour, while if you enter a jogging state, the speed at this time can reach 8km per hour. Su Bingtian's best time on the 100m track at the 2021 Tokyo Olympics was 9:83. He broke the best time for an Asian athlete.

And Bolt's best time in 2009 was nine seconds 58, which translates to about 45km per hour.

This is the fastest human runner on the planet, his running speed to the entire animal kingdom is nothing. An average adult cat can run as fast as 50km per hour.

In the herbivore world, there is an animal named fork-horned antelope, its running speed can reach about 100km per hour, and this animal, their growth rate is also particularly fast.

From the first day of life, four days later it can reach Bolt's speed, and even exceed Bolt's best performance. So with that said, you may think that the fork-horned antelope has such a running speed. They are not able to avoid the capture of all other carnivores?

Because they not only run fast, but also their endurance is higher than other carnivores, the answer is of course no. If that is the case, then their reproduction is very good. If that is the case, then their reproductive numbers will break the entire ecological balance.

In the entire surface animal kingdom, the fastest runner is the cheetah. Their acceleration of 100 kilometers takes only about three seconds. And the average running speed can reach 120km to 130km per hour.

Due to their special paw structure, they make their paws more favorable to grip the ground during running. So if you want to catch a fork-horned antelope, you can do it in a short time if the distance is suitable.

With such a fast running speed, it is clear that we can compare the speed of our cars. The fastest speed limit on our highway is only 120km per hour. If a car traveling so fast is involved in a car accident, it will be a car wreck.

And the time it takes to accelerate the Cheetah's 100km is far less than that of a car.

When our fingers touch the source of fire, we will quickly retract our hands under the action of the conditioned reflex. Then the nerve conduction speed in this process is about 290km per hour.

This speed can completely motivate us to avoid all possible instantaneous dangers.

The flying speed of the droplets spewed out when sneezing is about 300km per hour. Compared with the speed of our high-speed railway, you may feel a sudden realization.

And it is because of such a fast speed that it leads to the time when we sneeze, the droplets produced by sneezing without wind can still reach a distance of two meters away, or 9~10m away if it is downwind. So the mask will produce the best effect of isolating the virus.

The fastest animal of all species on earth is an animal named the peregrine falcon.

Although his usual horizontal flight process, the speed is only 100km per hour, when they are once found on the ground when they need to capture prey, they will quickly dive toward the ground, and the dive speed is up to 400km per hour.

The effect of gravity, as well as the special body structure, will make them reach this speed in a short period.

The speed of sound propagation in the air is about 340m per second, which is about 1225km per hour if converted to the speed of the hour. The Earth takes about 24 hours to rotate for a week, and a week of rotation near the equator is about 40,000 kilometers, then converted into the speed of the hour, the equatorial part, its rotation speed can reach 1700km per hour.

The Earth's rotation speed around the sun is about 108,000km per hour. In other words, humans living on Earth, are in this universe, although it seems to be stationary, we are in the moment at 108,000km per hour, towards the universe's non-stop flight.

So having said that, in this universe of ours, is there an object that transcends the speed of light or not? Although in Einstein's special relativity theory that all objects in this universe, its speed can not exceed the speed of light.

But there are certain phenomena in reality that have indeed exceeded the speed of light.

The first point is the speed of expansion of the universe. Scientists, through the observation of the cosmic microwave background radiation, finally confirmed that the universe we live in is spreading outward at a speed beyond the speed of light.

And the further away from us the planet, the faster they will spread. This is why we humans have so far only been able to observe an observable universe with a radius of 46.5 billion light years.

This does not conflict with Einstein's special relativity theory. The fundamental reason why the expansion of the universe can exceed the speed of light is that it started at the time of the birth of the universe.

And Einstein's theory only applies to objects that are in space, which cannot exceed the speed of light. And does not apply to this space itself.

Just think about it. Why can't we detect the world 46.5 billion light years away? Suppose our eyes can see infinitely far. But those cosmic objects 46.5 billion light-years away, are moving away from us at a speed faster than the speed of light. And the light in the opposite direction of their distance cannot reach our eyes in time, it has been pulled far away by the speed of expansion. So it causes us to see only this range.

There is another particle in the universe that can exceed the speed of light, and it is an example of a particle called a fast one, which scientists believe is already moving faster than the speed of light, and it will never go below the speed of light.

Similarly, the theory of factors does not contradict Einstein's theory of special relativity. Because Einstein's special theory of relativity does not deny a particle that is already moving in superluminal form. So there is no conflict between the two.

Of course, so far, scientists have not observed the existence of fast particles, but only at the stage of theoretical ideas.
