With recent developments in technology, instrumental precision is no longer the limiting factor in detecting Earth-analogue exoplanets using the radial velocity (RV) method. Instead, the astrophysical noise caused by stellar activity can mask or, in extreme cases, mimic planetary RV motions. Therefore, this thesis is dedicated to trying to better understanding the impact of stellar activity in ord

Instrumental precision is no longer the biggest impediment to the discovery of Earth-like planets. Indeed, future space missions and next generation spectrographs are technically capable at finding and characterising Earth-analogue planets. However, it is now stellar activity that poses a critical challenge on the pathway to detect habitable Earth-like worlds. This thesis is therefore dedicated to

<p dir="ltr">The GENESIS Black Hole–White Hole Multiverse Hypothesis proposes a model of cosmological reproduction in which gravitational collapse does not terminate at a singularity, but undergoes a black-hole-to-white-hole transition that seeds an expanding daughter universe. The hypothesis combines established and proposed results from general relativity, quantum-gravity black-hole transition m

<pre>It is commonly assumed that planets on close orbits cannot survive once their host stars expand into red giants, as stellar radii increase dramatically and tidal forces become destructive. This expectation underpins current views of planetary populations around evolved stars. While a single such system had been reported previously, we show that this phenomenon is not an isolated anomaly. The
