Which of the following statements regarding Dark Matter and Dark Energ...
Dark Matter and Dark Energy are two components of the universe that have been hypothesized to explain certain observations, but our understanding of them is limited. Let's analyze each statement to determine their accuracy.
1. Dark Matter is negative, repulsive force and acting in the opposite direction of gravity.
This statement is incorrect. Dark Matter is a hypothetical form of matter that does not interact with light or other forms of electromagnetic radiation, making it invisible. However, it is believed to have a gravitational effect on visible matter. Dark Matter is thought to be responsible for the observed gravitational effects that cannot be explained by the presence of visible matter alone. It is considered to be a form of matter that has not yet been detected directly, but its existence is inferred from its gravitational influence on visible matter.
2. Dark Energy is an attractive force that holds our world together as it interacts with gravity yet does not reflect, absorb, or emit light.
This statement is also incorrect. Dark Energy is a hypothetical form of energy that is believed to be responsible for the observed accelerated expansion of the universe. Unlike Dark Matter, Dark Energy is not a force that holds our world together. It is a property of space itself, causing the universe to expand at an accelerating rate. Dark Energy is thought to make up about 68% of the total energy content of the universe, while Dark Matter accounts for about 27%. The remaining 5% is made up of visible matter.
Therefore, the correct answer is option 'D' - Neither 1 nor 2. Both statements are inaccurate in describing the nature of Dark Matter and Dark Energy.

Which of the following statements regarding Dark Matter and Dark Energ...
- Dark matter acts as an attractive force, a kind of cosmic mortar that holds our world together, and not a repulsive force,
- This is because dark matter interacts with gravity yet does not reflect, absorb, or emit light. Meanwhile, dark energy is a repulsive force, a kind of anti-gravity that slows down the expansion of the universe, hence statement 1 is not correct.
- Whereas Dark Energy is a type of energy that exerts a negative, repulsive force, acting in the opposite direction of gravity.
- It has been proposed to explain the observed features of distant types of supernovae, which reveal the universe expanding at an accelerated rate. Hence statement 2 is not correct.
