What is naked singularity?

  1. Singularity that cannot be measured by any mathematical theory/ equation

  2. A space time singularity not surrounded by a black hole.

  3. The singularity from which the Universe emerged.

  4. None of the above

B Correct answer
Explanation

A naked singularity is a hypothetical gravitational singularity without an event horizon. Unlike black holes, which hide their singularities behind event horizons, a naked singularity would be visible from outside. This concept challenges the Cosmic Censorship Hypothesis, which proposes that all singularities must be hidden behind event horizons. Naked singularities remain theoretical and have not been observed.

What is a particle accelerator?

  1. A machine to seperate subatomic particles and study their behaviour under extreme volatile conditions.

  2. Instrument used to make atom bombs.

  3. A machine that ,using electromagnets can accelerate moving charged particles giving them more energy.

  4. None of the above

C Correct answer
Explanation

A particle accelerator is a machine that uses electromagnetic fields to propel charged particles (such as protons or electrons) to very high speeds and energies, often approaching the speed of light. These accelerated particles are then made to collide with targets or each other, allowing scientists to study fundamental particles and their interactions. Examples include the Large Hadron Collider (LHC) at CERN. They are essential tools for particle physics research, not for making weapons or separating particles.

what is Plank's Quantum principle?

  1. A space time singularity not surrounded by a black hole.Physicists have long thought--hoped--it could never exist but in reality it does.

  2. The idea that light or any other classical waves can be emitted or absorbed only in discrete quanta, whose energy is proportional to their wavelength.

  3. A theory inspired from heisenberg's uncertainity principle.

  4. none of the above.

What is quantum mechanics?

  1. General Relativity

  2. Hawkin's radiation theory

  3. The theory developed from Planck's Quantum principle and Heisenberg's uncertainity principle.

  4. none of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Quantum mechanics is the fundamental theory in physics that describes nature at the smallest scales of energy levels of atoms and subatomic particles. It developed from two key principles: Planck's quantum principle (energy is quantized) and Heisenberg's uncertainty principle (we cannot simultaneously know a particle's exact position and momentum). Unlike general relativity (which describes gravity on cosmic scales) or Hawking radiation (a specific phenomenon about black holes), quantum mechanics deals with the probabilistic behavior of particles and waves at the microscopic level.
