Dark Matter May Have Come Before the Big Bang! SciShow News

The video explores the mystery of dark matter, a substance that makes up about 80% of the universe's mass but remains undetectable. A new study suggests dark matter might have formed before the Big Bang, during cosmic inflation. This hypothesis aligns with existing knowledge and offers a framework for future research. The video also discusses neutron stars, focusing on a study of the vela pulsar, which revealed new insights into their structure and behavior, including unexplained rotational glitches.

What is the primary reason scientists study dark matter?

• To measure the temperature of the universe

• To detect new forms of light

• To explain the distribution and motion of galaxies

• To understand the chemical composition of stars

Why might dark matter be difficult to detect according to the new hypothesis?

• It is composed of easily detectable particles

• It is made of visible particles

• It formed after the Big Bang

• It formed before the Big Bang during cosmic inflation

What are scalar particles, as mentioned in the video?

• Bosons with a high spin

• Particles with a negative charge

• Bosons with a zero spin

• Particles with a positive charge

What does the new study provide in relation to dark matter?

• A way to convert dark matter into energy

• A theory that dark matter does not exist

• Mathematical evidence supporting a pre-Big Bang formation

• A new method to detect dark matter

What is a neutron star primarily composed of?

• Photons

• Neutrons

• Electrons

• Protons

What phenomenon did scientists observe in the Vela pulsar?

• A change in color

• An increase in size

• A decrease in temperature

• A glitch in its rotation

What unexpected behavior was observed in the Vela pulsar before a glitch?

• The star's size expanded

• The star's temperature increased

• The star emitted more light

• The star's rotation appeared to slow down
