The former Supergrass frontman said that the album contains "11 little sonic explosions".
"There's all kinds of references from space travel to fatherhood to love to war, exploring different things," he told BBC Breakfast. "It was playing with snapshots and observations I've noticed from books and movies. If something interested me I'd write it down."
On the album's title, he said: "It's the opening line of the first track, it had a feel about it. I liked the statement and boldness of it. It's a metaphor for the songs, [which are] 11 little sonic explosions."
Speaking about the album's leading single 'Hot Fruit', he explained: "It is a dark little number, [the video] definitely satisfied my sci-pi pangings. It ticked a lot of boxes for me."
Coombes also joked about his iconic sideburns, adding: "I had a bit of an accident a few months back, I took one of them off by mistake. I had to even them out but within 20 minutes they were back."
The singer-songwriter releases Gaz Coombes Presents... Here Come The Bombs on May 21 via Hot Fruit Recordings and EMI Label Services.
To support the album, he will perform at Manchester's Ruby Lounge on May 17 and London's Bush Hall on May 25.
