Big Echo

Critical SF


We accept original science fiction stories up to 4,000 words in length. While we delight in escapist fantasies, they are not what we are interested in publishing here. What we want most at Big Echo are thought experiments which push the conceptual and aesthetic boundaries of the genre. This means, among other things, we are always interested in seeing submissions from  members of traditionally under-represented communities  including women, people of color, LGBTQ+, people with disabilities, and those marginalized within or living outside the Anglo-American world.

Submissions should be sent as DOC, DOCX, or RTF attachments in standard manuscript form. Make sure the subject line begins with "Submission" and has the title of your story and your byline (e.g. Submission: Time Dogs/Peabody).

Simultaneous submissions are welcome but please inform us if they are accepted elsewhere.

If the story appears later in another venue, please credit Big Echo: Critical SF as the first publication.

Please e-mail your submissions to


SF and the Avante Garde

It was no accident, therefore, that the birth of the avant-garde coincided with the first bold development of scientific revolutionary thought in Europe.

Blow it all Up!

Experiment! Experiment! Experiment!
