Can a giant the size of the solar system walk at the speed of light?

What is the largest creature in the world? Someone, of course: whales, of course.

Indeed, whales are much larger than any other animal on Earth. A blue whale weighs at least 190 tons or more, and some people may not be able to understand the enormity of this number, but a simple comparison will make you understand that 190 tons is equivalent to the weight of 2,000 to 3,000 people.

If you have to dig deeper, you can only say that the blue whale is the largest creature in the world today. In the past, there were not many huge creatures on Earth except for blue whales. Billions of years ago, many creatures were huge, even centipedes were 3 meters long, and dragonflies were at least 1 meter long after smashing their wings.

Hearing this, you may not be able to imagine that if human beings had lived in that era at that time, it was a question of whether human beings could have survived.

Why, then, did humans believe that such a large creature existed in ancient times? That's because with the development of technology, humans see the difference between them and bacteria. Bacteria are very small to humans.

If bacteria had eyes, they would see a human body as big as the universe they saw. And for the universe, human beings are as small as a bacterium, because human beings cannot see the end of the universe. The so-called "there are people outside of man, and there is heaven outside the sky", maybe in the universe, there are creatures the size of planets, but we have not yet discovered it.

In fact, in many science fiction movies, we will see the shadows of some giants. Just imagine, if there really were a giant the size of the solar system in our real life, how would the world change? Will humanity's place on this planet change?

If such a giant really appeared in real life, in fact, humans might not have discovered its existence, after all, in its eyes, we are like bacteria. And his actions will not disturb the human race, after all, in his opinion, the earth can be played with at will like a table tennis. Therefore, humanity will also continue to exist on Earth.

So, how many times faster is this giant's appetite and walking speed than earthlings? This estimate is unimaginable. Some people think that it is possible for such a large giant to reach the speed of light when he walks.

But in reality, there are many factors to consider, because of the giant's size, there will be more resistance when walking, and it will be a little difficult for him to walk, let alone reach the speed of light.

And again, when it comes to his appetite. The largest blue whale on the planet eats 500 million tonnes of shrimp in a year; In ancient times, Kuafu was able to drink the dried seawater. Therefore, the amount of food of this giant is estimated to be less than that of several planets, and it will not be full.

As for what it feeds on, it's beyond our imagination. After all, the creature we can imagine can't satisfy its appetite.

You can't reach the speed of light. If there were a giant the size of the solar system, he would be very slow to move, and it would not be possible to reach the speed of light. And the speed of light requires very strict conditions, so it is impossible to do it.

A giant the size of the solar system can't reach the speed of light when walking. Because the speed of light is the fastest speed in a vacuum, nothing has been able to exceed the speed of light until now.

Suppose there were giants the size of the solar system and could move freely, they could reach the speed of light, but we don't know what will happen after the speed of light, because there is no faster speed than light in the universe for the time being.

If it can't be reached, human beings will be attracted to him by the planet, and the larger the volume, the greater the pressure, and they will not be able to go fast, but slower.

No. Because according to the theory of relativity, the speed of an object cannot exceed the speed of light, so it does not reach the speed of light.

If there were a giant the size of the solar system, he could walk the entire earth in one step. And he can definitely reach the speed of light when he walks. Every walk is measured at the speed of light.

Is the upper limit of life's body size calling for leakage**? Some people believe that the blue whale is the representative of the largest creature, and indeed, compared to humans or paramecium, the blue whale is surprisingly large.

A blue whale weighs at least 190 tons, which is equivalent to the weight of 2,000 to 3,000 people, and the huge size also determines the amount of food that the blue whale eats like a giant, and a blue whale eats at least 500 million tons of shrimp in a year.

In the past, in addition to the blue whale, there were many large creatures on the earth, hundreds of millions of years ago, a centipede was 3 meters long, and after the dragonfly wings, the length was at least 1 meter or more, there is no doubt that if human beings survive in the era of ancient biology is rampant, there is no advantage at all.

Therefore, some people believe that there are creatures dozens or even hundreds of times larger than blue whales, because they see the difference between humans and bacteria. For bacteria, the human body is the size of the universe, and the reason why bacteria don't know about the existence of humans is because they are so big.

And human beings are the same, some scientists admit that human beings are like a bacterium for the universe, and human beings cannot see the end of the universe because they are "only in this mountain", human beings are in the belly of the universe, according to this statement, planet-level creatures may also exist, but it is not clear what kind of food they live on.

And what would happen if a giant the size of the solar system appeared in front of people? Will humans be able to see this giant? Does this giant walk faster than the speed of light?

As far as the truth is concerned, if there really is a giant the size of the solar system, it appears in front of human beings, and we cannot see its existence, and even if this giant walks fast, it cannot exceed the speed of light.

One is that the giant is inherently difficult to move due to its large size and the resistance it encounters when walking, and the second is that in the theory of relativity, it is impossible for any object with mass to reach the speed of light, let alone exceed it.

No. Because according to the theory of relativity, when an object reaches the speed of light, time is relatively static, so it cannot walk at the speed of light.

The radius of the solar system from the sun to the orbit of Pluto reaches more than 6 billion kilometers, then the diameter of the solar system should be 12 billion kilometers. If a person is that big, it is impossible for humans to see, and it is impossible for humans to walk at the speed of light, because of their large size and the resistance they receive when walking, it is inherently difficult to move, and in the theory of relativity, it is impossible for any object with mass to reach the speed of light, let alone exceed it.

Yes, if a person is the same size as the solar system, he can walk faster than the speed of light, and the distance between the sun and the earth alone will take about 8 minutes, so you can see it.

No, Einstein's theory of relativity states that the speed of any object with mass can never reach the speed of light, which is the absolute speed.

Even if you can get very close to the speed of light, you can't reach it.

What if you had the speed of light? See how to travel around the solar system at the speed of light.

At present, there are only two recognized faster-than-light events: one is that the expansion speed of the universe can exceed the speed of light, and the farther away it is, the faster it expands; The second is that the speed of quantum entanglement is faster than the speed of light, and this phenomenon also exists, so it can be said that the speed of quantum entanglement is instantaneous beyond distance.

Some people may say that Einstein did not allow the existence of faster than the speed of light, but in fact Einstein had a better explanation for the speed of light: objects with rest mass are not allowed to reach the speed of light, and theoretically can only be infinitely close to the speed of light; Information cannot be transmitted faster than the speed of light. It just so happens that one of the two faster-than-light speeds mentioned above expands space, and the other faster-than-light does not transmit information, and quantum communication is mainly to ensure the security of information, not to really use quantum entanglement for communication.

Returning to the topic, if there is a huge creature that can cover a distance between the sun and the earth in one step, which is an astronomical unit (100 million kilometers), then does this achieve superluminal speed? Let's leave aside how this giant came into being, let's just say that it has taken this step. First of all, you need two conditions to find the speed:

Time + distance, and the distance taken by this step is 100 million kilometers, so where is the time? There is no way to say before, objects with stationary masses cannot reach the speed of light, so the giant's step can theoretically be infinitely close to the speed of light, so it will take at least 8 minutes and 20 seconds to take this step. Because this time is the time it takes for photons to travel from the surface of the sun to the surface of the earth.

If such a giant does exist, then it will be a particularly sluggish person, because the fastest speed of signal travel in its body can only be the speed of light, and its brain sends signals to its legs, hoping to take a step, only to wait until twenty minutes later to move, which will be very difficult.
