Answer:
If we are looking for evidence of something that exists outside of our visible Universe and leaves no trace within it, it seems that the idea of a Multiverse is fundamentally untestable. But there are all sorts of things that we cannot observe that we know must be true. Decades before we directly detected gravitational waves, we knew that they must exist, because we observed their effects.

Answer:
This is likely possible for a region whose matter density is higher than the normal average.
Explanation:
A galaxy is a collection of lumps in space which are clumped together and interact with each other. There are a lot of speculations on how galaxies were birthed. some believe its formed by a collection of massive gas, dust which eventually collapsed under their own gravitational pull. others says its formed by the combination of large lumps of matter which accumulated forming thee galaxies. The possibility of a galaxy forming is dependent on how massive the matter in the region of the universe is.

Answer:</h3>
35 meters
<h3>
Explanation:</h3>
<u>Data given;</u>
- Velocity of an object = 5 m/s
- Time taken = 7 s
We are required to calculate how far the object traveled.
Velocity = Displacement ÷ time
Displacement = Velocity × time
= 5 m/s × 7 s
= 35 m
Therefore; the object traveled 35 meters
The path followed by a projectile is called its <em>trajectory. (C)</em>
In the most common school situation<em> </em>... <u>with</u> gravity but <u>without</u> air resistance, the trajectory of a projectile is the shape of an inverted parabola (nose pointing up). That's the result of constant horizontal velocity and accelerated vertical velocity.
