Interstellar medium The interstellar medium is matter that occupies the space between star systems in a galaxy. There are three main types of nebula: Absorption or dark nebulae are made of dust and gas in such quantities that they obscure the starlight behind them, making photometry difficult. Reflection nebulae, as their name suggest, reflect the light of nearby stars.
Their spectra are the same as the stars surrounding them, though the light is bluer; shorter wavelengths scatter better than longer wavelengths. Emission nebulae emit light at specific wavelengths depending on their chemical composition.

In William Huggins noticed that many nebulae showed only emission lines rather than a full spectrum like stars. From the work of Kirchhoff, he concluded that nebulae must contain "enormous masses of luminous gas or vapour.
The majority of gaseous emission nebulae are formed of neutral hydrogen.
In the ground state neutral hydrogen has two possible spin states: List of interstellar and circumstellar molecules Dust and molecules in the interstellar medium not only obscures photometry, but also causes absorption lines in spectroscopy. Their spectral features are generated by transitions of component electrons between different energy levels, or by rotational or vibrational spectra. Often times to an even larger degree.
It actually made more sense for them to be looking at other possibilities than it did for them to have a sixteen-year long relationship.
They made good firsts; two people meeting on an adventure and falling in love. But it should have been short and passionate, not long and choppy. Eventually falling off the grid altogether, only seen again briefly during minor fights that lead up to the larger conflict.
But Gohan was already born and Trunks needed a mom. Instead, he went out into the wilderness to train himself for upcoming battles.
As his power level relative to the enemies waned, so did their mutual interests. Bulma continued to help train the Z Team and stayed in-tune with ongoing events. Yamcha drifted away from the main team, instead of going off to play professional baseball.
They may have wanted the same thing early on in Dragon Ball, but the further the series went on, the less mutual interests they had.
Only the best of the best can call themselves her equal. In the manga, she appears to be especially picky about her boyfriend being very handsome.Relative and Absolute Dating
Nothing less would do. In Bulma, we see a young woman with a genius-level intellect who wanted to travel the world and go on adventures with a boyfriend. In Yamcha, we see a young man who lived his childhood as a bandit and had a crippling fear of women. Using his strength as one of the strongest humans on Earth, he fought against many villains in Dragon Ball and Dragon Ball Z.
In fact, their off-screen interactions are implied to be just as low in Dragon Ball as Yamcha took off to go train in the wilderness for the World Martial Arts Tournaments. Even in the scenes with Bulma, Yamcha is rarely there. In one episode, Krillin talks about all the girls around Yamcha and Bulma gets extremely angry.
Explorations Through Time
When Bulma offered that to Vegeta, Yamcha reasonably showed obvious disgust and absolute surprise. Who can blame him? Or the lack thereof. Of the many things that make no sense about their relationship, the fact that its ending was never shown is certainly near the top. From around years old, Bulma and Yamcha were in an off and on again relationship.
