What is the unknown glue holding the universe together slowing the expansion due to dark energy?

The force, or glue, that holds the cluster together is gravity — the mutual attraction of everything in the Universe for everything else. The space between galaxies in clusters is filled with a hot gas.

What is the balloon analogy?

The Balloon Analogy is a simple-minded way to help describe (but not completely describe) two facts of cosmology that are difficult for many people to see, namely that the universe is expanding uniformly and that there is no center (and no edge).

What is the Centre of universe?

The universe, in fact, has no center. Ever since the Big Bang 13.7 billion years ago, the universe has been expanding. But despite its name, the Big Bang wasn’t an explosion that burst outward from a central point of detonation.

Where is dark energy found?

Dark energy makes up approximately 68\% of the universe and appears to be associated with the vacuum in space. It is distributed evenly throughout the universe, not only in space but also in time – in other words, its effect is not diluted as the universe expands.

How is the universe expanding like a balloon?

The balloon is the universe, and as more air is blown into it, you would see the space or surface area of the universe expanding and every point on its surface getting further and further away from one other. It’s been suggested that this idea ties into the likely existence of multiverses, or multiple universes.

Where is the universe expanding?

The universe is everything, so it isn’t expanding into anything. It’s just expanding. All of the galaxies in the universe are moving away from each other, and every region of space is being stretched, but there’s no center they’re expanding from and no outer edge to expand into anything else.

Is the universe expanding evenly?

Yet there is no centre to the expansion; it is the same everywhere. The Big Bang should not be visualised as an ordinary explosion. The universe is not expanding out from a centre into space; rather, the whole universe is expanding and it is doing so equally at all places, as far as we can tell.

What is dark energy and how was it discovered?

The evidence was based primarily on the faintness of distant supernovas compared to their expected brightness in a universe decelerating under gravity. The acceleration appears to be propelled by the repulsive property of space—sort of an “anti-gravity” that pushes rather than pulls—called “dark energy.”
