Alien like Space Travel

[MATHACID]

Hello.I am a aspiring engineer or physicist or computer scientist.While in high school(8th grade I am 13) I have had multiple chats with individuals about the topic of FUTURE LIKE SPACE TRAVEL.I don't mean flying saucers but spacecrafts that use magnetic levitation to leave earth's atmosphere , or Negative mass built spacecraft .I was wondering what are the possibilites of such technologies.

Magnetic levitation is unlikely, as you need strong fields which drop off rapidly with distance (faster than gravity), so even if you can levitate at small distances, it eventually fails.

Negative mass is not a thing.

Unlikely, as Swansont says, but it doesn't mean people don't come up with ideas. Try these if your interested.
