# DARK ENERGY

DARK ENERGY

LET US TALK ABOUT THE 96% OF OUR UNIVERSE OF WHAT WE HAVE NO EFFIN CLUE

HOW DO WE KNOW IT EXISTS:-

• UNIVERSE IS EXPANDING.
• SUCH A UNDER-DENSE UNIVERSE SHOULD BE GEOMETRICALLY WEIRD.
• EXPANSION IS ACCELERATION

EFFECTS ON UNIVERSE:-

• GRAVITAIONAL LENSING
• HELPS THE GALAXIES TO STAY TOGETHER
• WILL PROBABLY RESULT INTO THE BIG-RIP
• YEAH SO IT DOES EFFECT THE FATE OF OUR UNIVERSE

INTERPRETATIONS OF DARK ENERGY

1. # SIMPLEST INTERPRETATION

## “IT IS AN VACUUM ENERGY OR EMPTY SPACE ENERGY”

### MORE EMPTY SPACE ∝MORE DARK ENERGY

That is simply as the more empty space is created the more dark energy which proves all its points.

From this explanation we can simply approve all the points about dark energy as we can see as the more space is created more dark energy is created and thus this results into expanding of universe and as well increase the speed of expansion of the universe.

We can better understand this through the Friedmann’s equations:-

a = Scale factor

ä = Rate at which expansion is changing

𝜌(rho) = pressure due to fast moving atoms or radiation

From this equation we can understand how dark energy beautifully fits in the general relativity

# DARK ENERGY IS AN EXTRA-DIMENSIONAL OBJECT

• ## How dimensions react with our universe:-

According to the physicists there are numerous dimensions. String theory itself require at least 10 dimensions! We currently live in the fourth dimension or we can say truly master or experience or interact in the three dimensions

• 1st dimension:- It is simply a normal line along x-axis (e.g line)
• 2nd dimension:– It comprises of two axis and enabling the object to attain some height(e.g square)
• 3rd dimension:-it involves depth(the z-axis) and is cross section of three axis
• 4th dimension:- is TIME. Yeah, time enters our space-time graph.

#### TRY to catch up now as things are will become crazy now as we witness the physics break

• 5th dimension:– how easy is it for you walk 10 meters and now just imagine doing it with time moving through time would be as easy like walking you can travel from one time period to another just without any shitty time-machine or worm-hole shits.

(this includes only moving in positive direction.

• 6th dimension:- travelling through time in both forward and backward direction
• 7th dimension:- now how to explain this one. As we now by theory of parallel universe their infinite possibilities of an event in this dimension we can travel through all the possibilities of all the events basically in the 5th and 6th dimension we have similar history but this dimensions is full of chaos and uncertainty
• 8th dimension:- is more or what similar to 7th dimension but is know as infinity dimension as a plane of such possible universe histories, each of which begins with different initial conditions and branches out infinitely
• 9th dimension:the laws of physics as we know them can be manipulated or controlled
• 10th dimension:- the 10th dimension is of GODS (just a reference I don’t believe in god) you can create your one universe that is matter or space and even intelligent life well that is what is ironical we will talk about that later

## Dark Dimension

Well I see dark energy as some kind of this extra dimension which does not react with normal matter and light or does not react with matter and light in the normal way.

“dark energy is really something that makes my mind wonder all night and then ultimately realise that there is so much in this universe that we need to learn ”
