During the inflationary epoch, the rapid expansion of the universe produced primordial gravitational waves.

Inflationary cosmology is a theoretical framework that explains the rapid expansion of the universe in the early universe.

Inflationary cosmology predicts the existence of primordial gravitational waves generated during the inflationary epoch.

Gravitational wave astronomy aims to use gravitational waves to investigate the early universe, including the inflationary epoch and the Big Bang.

Gravitational waves from the early universe are extremely weak, making their detection challenging.

Gravitational waves from the early universe are expected to have frequencies in the hertz to kilohertz range.

Detecting gravitational waves from the early universe would have profound implications for cosmology, providing insights into the inflationary epoch, the properties of the early universe, and the origin of cosmic structures.

LISA is a proposed space-based observatory designed to detect gravitational waves from the early universe and other astrophysical sources.

The expected launch date of LISA is currently set for 2035.

LISA's primary scientific goal is to probe the inflationary epoch and the Big Bang by detecting gravitational waves from the early universe.

LISA is expected to have a sensitivity of approximately 10^-19 Hz, allowing it to detect gravitational waves from the early universe.

LISA is expected to be able to detect gravitational waves in the frequency range of 10^-18 Hz to 10^-16 Hz.

LISA's expected sensitivity and range will allow it to detect gravitational waves from the early universe, study the properties of black holes and neutron stars, and probe the nature of dark matter and dark energy.

Detecting gravitational waves from the early universe is challenging due to the weakness of gravitational waves, the distance to the early universe, and the presence of cosmic background noise.

Detecting gravitational waves from the early universe could have profound implications, including confirming the inflationary cosmology theory, providing insights into the properties of the early universe, and helping to understand the origin of cosmic structures.
