Start with a planet hitting the earth

Parallel universes, in fact, need to be understood simply.

There is a you in this universe, and there is also a you in another parallel universe.

This is a parallel universe.

In fact, they are two almost identical worlds, running in parallel according to the timeline.

This is a parallel universe.

In other words, Chen Yuan originally wanted to save Ya, but he did not use parallel universes to save her.

It's because all parallel universes with Chen Yuan's universe have the same timeline.

In other words, in that timeline, Chen Yuan's universe had no hydrogen atoms, so other parallel universes had also experienced star extinction, and all hydrogen atoms were gone.

Simply put, even if you go to a parallel universe, it doesn't make any sense.

And now Navi suspects that Chen Yuan and Ya come from a parallel universe.

"We are not from a parallel universe." Ya said casually, "but from another universe. That universe has died, so we come to your universe. We don't know much about this universe. Since you are this universe That’s just the right time to make a friend. Maybe we need your help.”

"The universe...is dead?" Navi frowned again: "Did it collapse?"

"No, our universe has different laws from yours." Ya said, "Our universe is expanding."

"Expanding?" Navi looked at Ya, and she frowned: "How is this possible? Dark matter has been being consumed, the universe has been collapsing, but your universe is expanding?"

"Dark matter and dark energy are being converted into new matter and being absorbed by celestial bodies. Without dark matter and dark energy, the universe has been collapsing rapidly, and the current rate of collapse has exceeded the speed of light."

"What's going on in your universe?"

Navi looked at Ya.

This is a universe completely opposite to the universe where Chen Yuan lives.

The reason why the universe is expanding is because dark matter and dark energy are increasing, causing the universe to expand.

In this universe, on the other hand, dark matter and dark energy are converting into matter, causing the universe to shrink.

Ya said: "Our celestial body has been shrinking and converting matter into dark matter and dark energy, causing the universe to continue to expand. Many years ago, the expansion speed exceeded the speed of light."

Hearing this, Navi was stunned, and she smiled slightly: "It's really interesting."

"There is still such a thing."

Navi seemed a little in disbelief.

"Wait a minute." At this time, Chen Yuan said: "You said that dark matter and dark energy can be converted into matter?"

This was something Chen Yuan didn't expect.

The reason why this universe is collapsing is because dark matter and dark energy are being converted into matter?

Chen Yuan looked at Ya: "Didn't it mean that dark matter and dark energy do not react with any matter or energy?"

If dark matter and dark energy can be turned into matter, wouldn't it mean that Chen Yuan wouldn't have to work so hard for hydrogen in the first place.

As soon as Chen Yuan said these words.

Both Ya and Nawei looked at Chen Yuan.

Ya showed a smile.

"In our universe, this is indeed the case, but in this universe, I'm not sure."

Ya looked at Navi.

Chen Yuan also looked at Navi and said, "If dark matter and dark energy can be converted into other matter and energy, can you do it?"

Navi stood up and said slowly: "The conversion of dark matter and dark energy cannot be done artificially. Even our Silver Wing Civilization does not have this technology."

"Of course, if you can develop this technology, you might as well tell me." Navi looked at Chen Yuan, who was a star.

By the way, the conversion of dark matter and dark energy into other matter and other energy is converted by the laws of the universe. If you want to artificially convert them, obviously this requires very strong technology.

What if dark matter can really be converted into other matter?

That means that all matter in a universe can continue to exist.

If a star is destroyed, it can be rebuilt.

Any element can be recreated.

The only question is, how can you use the dark matter and dark energy that permeate the universe to convert it into the material you want?

It can't be done artificially, but it can be done in this universe.

But changes in dark matter and dark energy have also led to a problem, which is the collapse of the universe.

If this continues, one day, the entire universe will either undergo a cosmic tear or collapse again into a singularity.

In that case, this universe will cease to exist, and the civilization in the universe will also cease to exist.

Thinking of this, Chen Yuan looked at Navi: "Doesn't the celestial body in your universe lose energy?"

"I remember, the evolution of celestial bodies..." When Chen Yuan said this, he paused. He was about to tell Navi that dark matter and dark energy were converting into matter. Aren't the objects also converting into dark matter and dark energy during their evolution?

But as soon as he said it, Chen Yuanna felt that something was wrong.

In Chen Yuan's universe, dark matter and dark energy exist because the evolution of celestial bodies leads to the consumption of matter and energy. Those lost matter and energy will be converted into invisible dark matter and dark energy.

But the evolution of celestial bodies in the universe where Chen Yuan was located all relied on the pressure caused by the terrifying gravity.

But the universe in front of us is very special.

What it has is repulsion.

Repulsion is unlikely to cause the consumption of matter and energy, although there is a mysterious force that can counteract this repulsion and ignite some stars.

But that mysterious force seems to be unreliable at times, such as: Mercury stars.

That is to say, in this universe, during the evolution of celestial bodies, the dark matter and dark energy converted from the consumed matter and energy are far less than the speed at which dark matter and dark energy are converted back.

"We are looking for the edge of the universe. Since you are from another universe, do you know where the edge of the universe is?" Na Wei's voice came.

Hearing this voice, Chen Yuan was slightly startled. He looked at Na Wei: "The edge of the universe..., if you are looking for the edge of the universe, wouldn't it be easy to find it?"

"The universe you are in is like a bubble. At present, this bubble is shrinking. In other words, as long as you continue to fly outward along a straight line, you can find the edge of the universe."

This made Chen Yuan very confused.

When Chen Yuan was in his universe, he couldn't run out of the edge of the universe because the universe was expanding at a speed faster than the speed of light, and he couldn't catch up.

But this universe is currently shrinking rapidly, so they can't find it?

If you just run in one direction, can't you hit the edge of the universe?
