Frequently asked about Stargate SG-1
Common questions people search for, with answers written by us at MoviesPack.
Who are the Goa'uld and why do they pose such a threat to humanity?
The Goa'uld are a parasitic alien species that take human hosts by burrowing into a person's brain stem and seizing control of their body. They have been posing as gods throughout human history — particularly ancient Egyptian deities — and use advanced technology stolen from other races to maintain their dominance. Their threat to Earth is existential: they previously enslaved humanity millennia ago and, once aware of the Stargate program, seek to reclaim Earth as a subject world.
How does Daniel Jackson's knowledge help SG-1 in the early seasons?
Daniel Jackson is a linguist and archaeologist who first deciphered the Stargate's cartouche symbols in the original 1994 film, making the entire program possible. His deep knowledge of ancient Egyptian, Mayan, and other lost civilizations allows SG-1 to translate Goa'uld technology, negotiate with alien cultures, and understand the mythological framework the Goa'uld used to enslave early humans. His civilian perspective also frequently provides diplomatic solutions that the military-minded team members overlook.
What is the significance of the Stargate network and how does it work within the show's lore?
The Stargates are a network of ring-shaped devices built by an ancient race called the Ancients (also known as the Alterans), which create stable wormholes between planets across the galaxy when dialed via a seven-symbol address. The network was established millions of years ago and was later co-opted by the Goa'uld to build their interstellar empire. SG-1's central mission is to explore this network, form alliances with other worlds, and find technologies capable of defeating the Goa'uld threat before it reaches Earth.
What happens to Daniel Jackson when he ascends, and does he truly die?
At the end of Season 5, Daniel Jackson absorbs a lethal dose of radiation and is given the option by Oma Desala — an ascended being — to shed his physical form and join a higher plane of existence as pure energy, effectively ascending rather than dying. He spends Season 6 as an ascended being but is stripped of his memories and returned to human form by the Ancients for interfering in mortal affairs. His arc underscores the show's recurring theme that ascension is not necessarily a reward, as the ascended Ancients are bound by strict non-interference rules that frustrate Daniel's desire to help.
How is the Ori different from the Goa'uld as a villain threat in the later seasons?
While the Goa'uld falsely claimed to be gods to control humans through fear and technology, the Ori are Ancients who genuinely feed on the worship of mortal beings, drawing actual power from their followers' devotion. The Ori demand religious conversion under their faith called Origin and dispatch warrior Priors to spread their doctrine across the galaxy, promising ascension to believers but actually draining their life force. This makes them a more insidious threat than the Goa'uld — the enemy is not just military power but a spreading ideology backed by seemingly miraculous abilities.
