For instructions on applying, use the official Grants.gov search page, filtering by agency and entering keywords such as “gravitational physics,” “cosmic frontier,” or “quantum gravity.” Review each opportunity’s full Funding Opportunity Announcement for specific research areas and eligibility requirements.
DARPA Grants
While the Defense Advanced Research Projects Agency (DARPA) does not fund grants explicitly for “gravity manipulation,” it actively solicits proposals for high-risk, high-reward research in fundamental physics, precision sensing, and revolutionary systems.
Your most direct path for submitting speculative physics proposals is through DARPA’s Office-wide Broad Agency Announcements (BAAs).
Primary DARPA Offices for Advanced Physics Research
DARPA’s research related to advanced physics and extreme sensing is typically housed within these two technology offices:
| DARPA Office | Core Mission & Relevance | Target Area for Physics Ideas |
| Defense Sciences Office (DSO) | “DARPA’s DARPA.” Seeks revolutionary advances in science, devices, or systems, pushing scientific limits. | Fundamental Physics, Quantum Effects, Revolutionary Control over Physical Forces, New Forms of Matter/Energy. |
| Microsystems Technology Office (MTO) | Focuses on miniaturized components and systems. | Precision Inertial Sensing, ultra-low SWaP (Size, Weight, and Power) passive navigation, Chip-scale Quantum Sensors. |
Current Open Office-wide BAAs (Rolling Submissions)
DARPA uses these Office-wide BAAs to fund ideas that are not tied to a specific pre-existing program. They are the best mechanism for submitting unique or speculative proposals.
1. Defense Sciences Office (DSO) BAA
- Funding Opportunity Title: Defense Sciences Office (DSO) Office-wide BAA
- Funding Opportunity Number: HR001125S0013
- Current Deadline: Proposals accepted on a rolling basis until June 2, 2026.
- Key Interest Area: Proposals in the “Sensing, Measuring, and Affecting” thrust area are highly relevant, as they address developing new science to overcome limitations in measurement and control.
2. Microsystems Technology Office (MTO) BAA
- Funding Opportunity Title: Microsystems Technology Office (MTO) Office-wide
- Funding Opportunity Number: HR001124S0028
- Current Deadline: Proposals accepted on a rolling basis until December 1, 2025.
- Key Interest Area: Relevant for concepts that involve miniaturized sensors or microsystems that can detect or interact with fundamental forces, such as next-generation precision accelerometers and gyroscopes.
Crucial Recommendation for Submission
Given the highly specialized nature of this research, DARPA strongly encourages potential proposers to submit an Executive Summary or Abstract before preparing a full proposal.
This step is essential to confirm that your concept—even if it relates to “gravity manipulation”—aligns with the specific, mission-focused goals of the respective DARPA office (DSO or MTO), saving you the time and expense of preparing an out-of-scope proposal.
