Questions & Answers

Q: Can the LHC catch Dark Matter particles by running at full speed?

Dark Matter particles don't interact with electromagnetic spectrum, making it unlikely for LHC to catch them even at full power.

Q: Are WIMPs the only viable contender for Dark Matter?

While WIMPs are a leading contender, other theories like modified gravity and massive particles are under consideration for Dark Matter.

Q: How do gravitational waves reach Earth before gamma-ray bursts?

Gravitational waves travel at the speed of light, but visible radiation is generated after the shockwave, causing a delay in arrival.

Q: Why do planets in images appear black and white?

Images are taken in different filters for higher resolution and later combined to create full-color images, prioritizing science over aesthetics.

Q: How would the Solar System change if Jupiter ignited as a second sun?

A binary star system with Jupiter as a second sun would have dramatic effects, changing orbits and planetary dynamics fundamentally.

Q: Can a vessel be created to kick space junk back to Earth?

Efforts exist to clean up space junk, but challenges like costs and competing priorities hinder progress in launching debris removal missions.

Q: Will the theory of everything explain everything in the universe?

The theory aims to unify various forces, but chaos theory and uncertainties ensure that not every outcome can be predicted, leaving room for unknowns.

Q: Why do people ask questions easily googled?

Trusted sources and verification of information online are crucial, leading people to seek answers from reliable sources like experts in the field.
