Answer 1

Answer:

Hey mate your answers are------------------------

Ans 1. Dark matter is a hypothetical invisible mass thought to be responsible for adding gravity to galaxies and otheSound does not travel at all in space bodies. Since the amount of visible material in galaxies can't account for their shapes, distributions, and movements, astrophysicists argue there must be a form of mass yet to be discovered.✨✨

Ans 2. In physical cosmology and astronomy, dark energy is an unknown form of energy that affects the universe on the largest scales.✨✨

Ans 3. No one knows exactly what was happening in the universe until 1 second after the Big Bang, when the universe cooled off enough for protons and neutrons to collide and stick together. Many scientists do think that the universe went through a process of exponential expansion called inflation during that first second.✨✨

Ans 4. The event horizon is where the escape speed exceeds the speed of light: you'd have to be going faster than light (which is impossible for any bit of matter) to escape the black hole's gravity. Inside the event horizon is where physics goes crazy. ... A singularity is what all the matter in a black hole gets crushed into.✨✨

Ans 5. The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound.✨✨
