Can a spaceship fly to the galaxy 1 and a half now?

A: Theoretically, through the gravitational tunnels between the stars and so on, if he is not hit by a meteorite or otherwise disturbed in the middle of the way, then he will reach the center of the galaxy sooner or later, a matter of time. It's just too long.

The diameter of the Milky Way is about 100,000 light-years, half of which is 50,000 light-years, and the light will travel for 50,000 years.

Recently, science talked about the universe, and I wondered when people would be able to fly out of the Milky Way. A: Reference:

Outside the river system, there is a galaxy called Andromeda. Will there be an earth in it too?

A: There are very likely terrestrial planets in there, but you don't need to look so far, our galaxy itself is very likely to have planets that are very similar to the Earth, or even have the same life. Scientists estimate that there are billions of terrestrial planets in our galaxy.

About 10 (10 28) meters away there is a galaxy identical to our Milky Way, and there is an identical you in it.

At present, human-made space probes have not yet flown out of the solar system.

The diameter of the Milky Way is about 80,000 light-years, and the solar system is on a spiral arm outside the Milky Way, about 30,000 light-years away from the galactic center, and it may take a while to fly people out of the solar system.

Andromeda is the first extragalactic galaxy discovered and identified, and it is twice the diameter of the Milky Way. Imagine that there are 200 billion stars in the Milky Way galaxy, and the solar system is just one of them. So no matter what others think, I believe that there must be other intelligent beings outside the solar system (and you can object to it).

However, it is a pity that so far, human observation methods have not found a planetary system similar to the solar system outside the solar system.

It is possible, but it will be a long time, and if you want to fly out of the galaxy, you must first have new fuel, and if you want to fly out of the galaxy, the spacecraft must be at a speed of 200 kilometers per second. Because the diameter of the Milky Way is 100,000 light-years (the speed of light is 300,000 km/s, and 100,000 light-years means that light travels 100,000 years).

In addition, the distance between the solar system and the center of the Milky Way is 30,000 light-years, indicating that the solar system is at the edge of the galaxy and is still 20,000 light-years away from the edge. (It will take 20,000 years).

Also, even if a human spaceship could fly at a speed of 2 million kilometers per second, the people sitting in it would be scared to death by such a fast speed

I'm playing hard, please support me, thank you for your cooperation!

Possibly, after all, there are so many wonderful things in the universe that you can't say everything, and you can be hungry for everything.

Impossible, the Milky Way is very big.

The radius of the solar system is about 6 billion kilometers, and it takes about 6 hours to fly out at the speed of light. The position of the Sun is about 1 3 from the center of the Milky Way, the diameter of the Milky Way is about 900 million light-years, and it takes about 30,000 years to fly out of the Milky Way at the speed of light.

Lightspeed refers to the speed at which light waves or electromagnetic waves travel in a vacuum or medium. The speed of light in a vacuum is the maximum speed of motion of an object in nature that is found.

It is independent of the speed of the observer relative to the light source, i.e. the speed of light measured in the inertial frame relative to the stationary and moving light source is the same. The mass of an object is also related to the speed at which it moves, the mass of the object will increase with the increase of velocity, and when the speed of the object is close to the speed of light, its mass will tend to infinity, so it is impossible for an object with mass to reach the speed of light.

Only photons with zero rest mass begin to move at the speed of light. The speed of light is superimposed on any speed, and the result is still the speed of light. The synthesis of velocity does not follow the laws of classical mechanics, but follows the relativistic laws of velocity synthesis.

Methods for the study of the speed of light:

The determination of the speed of light involves the measurement of the distance and the time it takes for light to pass, because the speed of light is very large, so it is necessary to measure a long distance and a very short time, geodetic is around how to accurately determine the distance and time and design of various methods.

As early as 1629 Isaac Bickman proposed an experiment in which a man would observe a flash of light reflected in a mirror, about a mile.

Galileo believed that the speed of light was limited, and in 1638 he asked two men to climb a mountain only about a kilometer apart with a lantern, and the first group lifted the lantern and began to time it.

This is the most famous scheme for measuring the speed of light in history, and what is actually measured by this measurement method is only the reaction of the experimenter and the time of human hand.

For now, humans can't fly out of the galaxy. Given the scale of the universe, any travel between galaxies is far more difficult than we currently consider feasible propulsion methods, even to accelerate a large spacecraft close to the speed of light.

According to the current understanding of physics, it is impossible for an object in space-time to exceed the speed of light, which means that it would take millions of Earth-years to fly away from the Milky Way by traditional means of flight. In other words, with the current state of technology, it is difficult for humans to fly out of the galaxy. It can only depend on the development of science and technology in the future.

The theoretical method of human flight out of the galaxy.

While it would take about 2.54 million years to cross the space divide between galaxies, it would take much less time from the perspective of a traveler approaching the speed of light.

The time experienced by a traveler depends on speed (anything less than the speed of light) and distance traveled (length contraction). Thus, from a traveler's point of view, interstellar travel for humans is theoretically possible. Accelerating to a speed close to the speed of light with a relativistic rocket will significantly reduce the travel time on the spacecraft, but requires a very large amount of energy.

It takes 30,000 years for a rocket to travel a distance of 1 light year. The speed of light is 300,000 kilometers per second. The rocket reaches a cosmic velocity of 7 to 11 kilometers per second, calculated at 10 kilometers per second.

1. According to the data, the rocket speed can be reached at present, and I take it for the convenience of calculation. Known distance s 1400 light years 1400 3 10 5 365 24 60 60km.

2. T s v can be calculated as T 1400 3 10 5 365 24 60 60 years of defense and Yuyu.

3. One light-year is the distance that light travels in one year, that is, about 9,460 billion kilometers. According to the rocket speed there are kilometers and seconds, multi-stage up to kilometers and seconds, and the second cosmic speed kilometers and seconds.

Light-year measurement principle:

Light-years are often used to measure very long distances, such as the distance between the Sun and another star. A light-year is not a unit of time. In astronomy, another commonly used unit of distance, the second difference is light-years.

The distances between objects in the universe are too large to be cumbersome to measure in kilometers, but it is much easier to measure in light years. The distance that light travels in a year in a vacuum is called a light-year. The speed of light in a vacuum is about 300,000 kilometers and seconds, or 3,108 meters and seconds, so one light-year is meters.

For example, the world's fastest aircraft can reach speeds of up to 11,260 kilometers per hour. At this rate, it would take 95,848 years to cover 1 light-year. The average flight speed of an airliner is about 885 kilometers per hour, and it takes 1220330 years to fly 1 light year.

The Milky Way is 100,000 light-years in diameter, even if humans invent antimatter photon rockets, it will take 40,000 years to fly out of the Milky Way at a speed close to the speed of light, which is obviously too long For humans to fly out of the Milky Way, they must invent a breakthrough to break through the barrier of light, or borrow a wormhole, otherwise it is impossible, Andromeda, which is relatively close to the Milky Way, has 220w light-years, what to fly.

With Earth's current technology, it is impossible to fly out of the galaxy! But it will definitely be possible in the future, after all, the current technology of the earth has only been developed for a hundred years and has reached supersonic speed! In many science fiction movies, we have seen human beings carrying spaceships of their own design to various places in the universe to carry out missions and immigration, and it can be said that "walking" out of the earth and flying out of the galaxy is the common dream of mankind.

The most important thing that human beings need at present is how to fly out of the solar system, and as for flying out of the Milky Way, it will be hundreds of billions of years later, just like a primitive society trying to guess that people in today's society can travel in the sky on planes, which is an unimaginable problem. One staircase and one pavilion, the endless pavilion stretches to the sky, and going out of the solar system is the science and technology that human beings urgently need today.

Not at this time. The future must be possible, because the development of modern earth technology has developed very quickly, and in many science fiction movies, we see a man's tower with a spaceship of its own design to carry out missions and migrants around the world.

Time is running out, what else do you study, Jesus is coming back, you have a soul, what do you live for every day, do you want to study what you can't do, you have a soul of your own, I want you to save him, people should get rid of illusions, work hard for the soul that really exists, look for Jesus, your direction should be to find Jesus, save your soul.

There is no way to do this now, it does not mean that there will be no way in the future, one day human beings will rush out of the galaxy, but this will take a long time to accumulate.

The solar system can't fly, let alone the Milky Way.

No human beings have yet left the solar system, and technology and time do not allow it. However, in 1977, humans had already sent two Voyager outer solar system explorers to the solar system, and Voyager 1 has now flown out of the solar system, and Voyager 2 is about to leave the solar system, and as of 2011 it is about 14 billion kilometers away from the Earth.

The Challenge: A Time Problem.

It is still very far away to send humans out of the solar system with a radius of 14 billion kilometers at the speed of Voyager 1 and 2, because these two explorers have been 41 years since they set off, and 41 years is too long for us humans. Unless we can find a way to stay alive in space, or faster.

The radius of the solar system is about 6 billion kilometers, and it takes about 6 hours to fly out at the speed of light. The location of the Milky Way is about 1 3 meters from the center of the Milky Way, the diameter of the Milky Way is about 900 million light-years, and it takes about 30,000 years to fly out of the Milky Way at the speed of light.
