Seeking a sci-fi movie, it is a time-traveling type, originally introduced in the sci-fi world

The content was roughly as follows: There was a family traveling in space by spaceship. One of the little boys was a genius. He calculated that he could use a method to travel through time and space, but his parents did not believe it, making him very depressed. At this time, their spaceship had a problem and crashed on a planet. Everyone was in a dangerous situation. Suddenly, their family discovered that there was a kind of bubble on the planet, so they walked in... There was an old man inside (there seemed to be another person, I don't remember). The old man was very excited when he saw the family and called the little boy's father 'daddy'. It turned out that the old man came from this planet more than 20 years later. He was the little boy himself. According to the old man, after the crash, all of you died due to some kind of sudden disaster. Only I survived. I used the existing materials on the spaceship to create a time machine based on my theory. I wanted to stop all of this from happening and let everyone survive. So I returned to the time and place where the spaceship crashed and told you how to avoid this disaster. At this time, the time machine he made had a problem...
I don't remember the rest. I hope some friends who know can tell me the name of this film. I want to download it. Thank you very much.

What you want is a sci-fi movie that travels through time and space. I've introduced it to the sci-fi world before, and that's The Time Machine. The movie was released by Warner Brothers in 1984 and directed by George Lucas. It tells the story of a scientist who invents a machine that can travel through time and space and embarks on a journey full of adventure and challenges with him. The film received very high reviews and became one of the classic sci-fi movies that traveled through time and space.
