It's actually explained on the wiki that he teleports by folding space. As for how Gojo can fly, I think it can be explained by the theory of general relativity as it basically explains how gravity is simply a side effect of the distortion of space caused by a large amount of mass or energy, since Gojo's ability grants him control over space that also means he has control over gravity thus allowing him to negate it's affects on him.

For everyone that doesn't fully understand how the limitless works, allow me to explain. Limitless: The signature cursed technique of the Gojo clan which allows you to bring the concept of infinity into reality, allowing the user to distort space at will, with only those who possess the six eyes being able to utilize the ability to the fullest, however only 1 person can manifest the eyes at a time. Neutral Limitless: Infinity Simply put, it's the division of space. In mathematics a number can't reach 0 no matter how many times it's divided, instead you will be left with fractional units so infinitesimal it would become immeasurable to the naked eye. Since speed= distance/time, whenever Gojo utilizes the limitless to bring this mathematical concept into reality, it causes objects to move slower the closer they get to Gojo. Strengthened Limitless: Blue Simply put, its the subtraction of space. By amplifying the cursed energy output of the limitless, the user is able to bring the conceptual impossibility of negative distance into reality, when an area of space is erased by blue the surrounding space is forced to correct the impossibility by violently converging toward the area, resulting in a powerful magnetic like affect. Gojo can take advantage of this affect in various ways like, Surrounding a person with blue, causing their body to be crushed by the converging space, utilizing maximum cursed energy output in order to create a massive singularity that attracts everything around it, enhancing his own speed by making the space around himself converge toward a direction, use a powerful form of telekinesis to throw around opponents as well as buildings and even being able to imbue his physical attacks with it as well to increase the force of the impact by making the opponent converge toward his fist. Reversed Limitless: Red As the reverse of blue, red adds space instead of subtracting it, resulting in the surrounding space violently diverging away from the affected area rather than converging toward it. When red is used it is able to produce twice the cursed energy output of blue and create massive blasts of energy that instantly kill most enemies, however outside of attacking it doesn't seem to possess as much utility as blue. Colliding Limitless: Purple The fusion of both red and blue, as well as a secret ability known only to a select few of the Gojo clan, a fusion of convergence and divergence that collides both infinities in order to generate an artificial mass. An imaginary mass is a concept that exists in theoretical physics and is created when you take the square root of the value of a negative particle resulting in something that functionally shouldn't exist, causing matter that it comes into contact with to be erased from existence. Gojo of course also possesses the ability of long range teleportation but it isn't really explained how he does it exactly, only that he just can.
