Guys I know this is absurd, but it kinda makes sense to me. Recently, while i was doing housekeeping, I asked my brother to throw a piece of sponge down. He compressed the sponge and dropped it down. While the compressed sponge was falling, I saw it expanding. Seeing this, I realized that the expansion of the sponge is similar to the concept of our universe expanding. This led to me wondering, how is it possible for our earth, solar system and Galaxy to suspend in the universe? Is it because our universe is like a falling compressed sponge, which is just trying to expand to its original size? Because the universe is constantly falling, all the galaxies, solar systems and stars fall together with the universe. Also, the speed of our universe falling could be so fast, maybe falling at the speed of light, that vacuums are created in space, that led to us not realising it.The stars and galaxies could be like the particles in a piece of sponge. While the universe expands, it sucks in new material from beyond the universe and this brings in energy which kept our system moving.
