[doppypoppy]

[titusilvering]

can someone explain to me?

Infinity

 

[Sephirot]

Don't need think too much on this we will never know.

 

[newborn1000]

Tell us 1 number , then later change number again anyways...

 

[Shion]

there is no answer to this

 

[SecretAgent]

Large to a point where it is just one atom short of being infinite?
Cause if it is immeasurable, everything won't make sense anymore

 

[Dopod007]

Universe is like going round and round circles, cannot see the end....

 

[Cowbellc]

im thkin hor...btw Milky Way n Andromeda galaxy, wats btw them, juz a black void wif nth?

 

[Ethan_]

Its expanding, if not wrong.

 

[Suporter]

Beri large

 

[orpisia]

What if the universe had always been there

What if there was no beginning of the universe

Can the human brain even comprehend that

 

[Can Or Not]

When your PC ask you to stand by Universe, you forgot to ask

 

[AUTUMN&WINTER]

No beginning and no ending. The nature of our universe is cyclical. Life cycle, water cycle, day and night rotates, high tide low tide, flowers bloom flowers wither etc. No need to know how large is our universe, better concern where we will be going in our afterlife. If you don't know where you came from, you must know where you will be going. 不知从那里来， 但知往那里去。

Strange paradox discovered by scientists.

We all know the maximum possible speed limit is the speed of light.

The universe is expanding so fast that it is faster than the speed of light.

so there are some planets and solar systems that we can never reach, coz it is physically impossible.

 

[fandango]

What is the size of Uranus?

 

[Dinoboyboy]

Larger than a dinobu drinking 100% sugar bbt daily.

 

[kreja]

Idk but its good that there are smart people who will go find out.

Light-year is the distance light travels in one year. Light zips through interstellar space at 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year.

10 to the 80th power of atoms in the universe


u/ablativeyoyo

10^27 atoms in a kilogramme of hydrogen
10^30 kilogrammes in an average star
10^11 stars in an average galaxy
10^12 galaxies in the observable universe

27 + 30 + 11 +12= 80

Total of 10^80 atoms in the observable universe. Obviously, there's a fair bit of uncertainty in all these figures.

 

[nasilemak100]

it is ever expanding. and fastest speed is cap at speed at light.

it is as though something or someone want to ensure that even if u can achieve travel at light speed, u still can't travel to end of universe and discover what is beyond it

 

[0nePunchm@n]

It is infinite & limitless because it continues to die & newly created
