Frequently Asked Questions (FAQs) - NSF Gravitational Theory Program (PD 11 1252)

What is the NSF Gravitational Theory program (PD 11 1252)?

The NSF Gravitational Theory program (Funding Opportunity Number PD 11 1252) was a discretionary grant opportunity within NSF's Mathematical and Physical Sciences area (CFDA 47.049). It focused on advancing fundamental research in gravitational theory, including both classical and quantum approaches.

What kinds of research did the program aim to support?

The program aimed to support fundamental work in gravity theory, especially research that tackles situations where gravity is strongest or most complicated. This included strong-field regimes near compact objects and theoretical foundations relevant to understanding gravitational waves and their sources.

Did the program support both classical and quantum gravity?

Yes. A core purpose of the program was to support work in both classical gravity theory (including general relativity and related frameworks) and quantum gravity theory, including efforts that explore the relationship between gravitation and quantum mechanics.

What does "bridging gravitation and quantum mechanics" mean in this program's context?

A key theme was research addressing the conceptual and mathematical tensions between general relativity and quantum theory. Proposals could focus on developing frameworks, methods, or models that help connect or reconcile aspects of the two, or otherwise clarify their relationship.

Was the scope limited to purely theoretical work?

No. While the emphasis was on gravitational theory, the supported scope was described as broad and could include theoretical and computational research, and in some cases efforts that were experimentally connected (for example, theory work tied to interpreting observational or experimental results).

What types of activities were considered typical or encouraged?

Typical activities included formulating clear, quantitative hypotheses; analyzing them using analytic approaches and numerical or computational tools; and, where applicable, helping interpret experimental or observational outcomes.

Did the program include gravitational-wave-related research?

Yes. The opportunity specifically highlighted interest in theoretical foundations for understanding gravitational waves and their sources, including modeling and simulation of gravitational wave sources (such as events involving compact objects).

What is meant by "strong-field regimes near compact objects"?

In the program description, this phrase referred to physical settings where gravitational effects are extreme or highly non-linear, such as environments around compact objects (for example, black holes or neutron stars). The program emphasized theory relevant to these regimes.

Did NSF emphasize interdisciplinary work under this program?

Yes. NSF noted that many awards in this area crossed traditional boundaries. Interdisciplinary connections could include links to astrophysics, cosmology, particle physics, mathematics, computational science, or other areas (including instrumentation and data methods when theory is closely tied to measurements).

Besides research grants, what other kinds of support were included?

In addition to direct research awards, the program supported activities intended to strengthen the research community and accelerate progress. Examples listed included short- and long-term visitor programs, workshops, and research centers.

Who were these community and infrastructure activities intended to involve?

These activities were intended to bring together external scientists from universities, national laboratories, and industry. They also aimed to provide meaningful participation opportunities for graduate students and postdoctoral researchers.

What type of funding instrument was used?

The opportunity used a grant funding instrument.

What was the overall activity category for this opportunity?

The listing identified the activity category as "Science and Technology and other Research and Development."

When was the opportunity posted?

The opportunity was posted on May 13, 2011.

What was the full proposal target date?

The original full proposal target date was October 26, 2011.

Was this an annual opportunity?

The notice indicated an annual target date pattern: the last Wednesday in October was identified as the annual target date after the initial 2011 target date.

Was cost sharing or matching required?

No. The listing indicated there was no cost sharing or matching requirement.

Who was eligible to apply?

Eligibility was described as unrestricted (open to any type of entity), subject to any clarifications provided in the official opportunity text.

Is this funding opportunity still open?

No. This opportunity is archived. It was replaced by PD 13 1252, and the archive date for PD 11 1252 was September 19, 2013.

What opportunity replaced PD 11 1252?

The archived opportunity indicates it was replaced by PD 13 1252.

The listing shows expected awards and estimated total funding as 0. Does that mean there was no funding?

Not necessarily. Based on the listing notes, the "0" values are best interpreted as the snapshot not specifying amounts, rather than as a definitive statement about actual NSF funding levels.

Where were applicants directed for access or submission support?

For access issues, the notice directed applicants to NSF Grants.gov support via the email address grantsgovsupport@nsf.gov.

Which NSF area and CFDA number were associated with this program?

The opportunity was in the Mathematical and Physical Sciences area and was associated with CFDA 47.049.
