What if humanity hadn t yet achieved interstellar voyage when the Earth was about to be destroyed?

Then we can only build a spaceship and load some human beings to wander in the universe and continue to look for planets where they can live.

If the interstellar voyage has not yet been realized when the earth is about to be destroyed, it means that there is no ability to escape from the earth, and it can only be destroyed with the earth.

Then there is no way. The vast majority of humanity will perish. Perhaps a very small number of them will take a spaceship and start wandering in space with human genes.

Just like Star Trek.

I think it's a bit unrealistic for humans to realize interstellar travel in the future, at least for the next 100 years. The so-called interstellar travel, in fact, means that human beings can fly out of the solar system, at least should reach the nearest star to the earth, but it is obvious that this idea is a little crazy, although the current speed of technological development is very fast, but if we look at it calmly, it is indeed very difficult to realize this idea. <>

In fact, we can take a look at the development journey of the world's aerospace industry, as early as the end of the 60s of the last century, the Americans have landed on the moon, there is no doubt that the United States is indeed far ahead in space technology, even now, the United States is still the world's leading space technology. After the Americans landed on the moon, mankind has made a lot of achievements in space technology, such as the emergence of the space shuttle, the space station, the landing of the Mars rover, and later the exploration of Pluto by New Horizons. <>

Although we are very proud of the achievements we have made in this area, now half a century has passed, and our rocket launch capability has not actually surpassed that of the American Saturn 5, that is, in fact, our own rocket launch capability has not been qualitatively improved. In addition to this, we can also take a look at the speed of the ship. Back in the last century, the Soviet Union created the first artificial satellite, which flew at a speed of kilometers per second.

And now the solar probe invented by the United States has a flight speed of more than 100 kilometers per second, and this speed has set the highest record, but even this speed is still far from the speed of light, and even the speed of light cannot reach 1. <>

So through the above analysis, we can see that in the next 100 years, or even a long time, it will be impossible for us to achieve the so-called interstellar travel. In the next 100 years, if we can achieve a round trip to Mars, it will already be a big achievement.

I think it is possible, with the development of consciousness upload technology, human beings have made breakthroughs in the field of manned spaceflight, and the dream of assisted interstellar travel will eventually become a reality.

It is very likely that mankind will achieve interstellar travel in the future, and now that super-Earths have been discovered, it will soon be possible to discover places suitable for human activities.

It is very likely that with the development of scientific and technological prowess, interstellar travel has become a romantic fantasy for many people, and it will come true one day.
