It’s been proved that universe is expanding, so does that mean that atoms, cells, people, stars and everything in this universe is getting bigger and bigger?

Heya...Empress Here!!

• No, Of course not. Even if the universe is expanding, the objects inside it are still the same size. Universe is only expanding its boundaries and forming new planets and stars.

• Just an example :- Take a balloon and fill it with candies. Now fill the balloon up with air. Only the balloon with experience expansion, not the candies. They'll remain of the same size.

who told u universe is expanding. it is not expanding. when someone say universe then he is comprehending the whole. nothing is left. if it is expanding then what stuff is outside it.
now about the observations which supports that universe us expanding.
One of the most inserting predictions of theBig Bang conception that usual geometry does no longer work at fine distances

within the residence circular us, on earth, in the solar method and our Milky manner Galaxy, as an same objects get farther away, they look fainter and smaller. Their floor brightness, that is the brightness per unit discipline, stays steady.
In distinction, the massive Bang idea tells us that in an increasing Universe objects simply will have to exhibit up fainter nevertheless higher. For this reason in this proposal, the external brightness decreases with the hole. Additionally, the sunshine is stretched because the Universe accelerated, extra dimming the sunshine.
So in an increasing Universe nearly essentially the most distant galaxies will have got to have 1000's of hundreds of thousands of situations dimmer floor brightness than same local galaxies, making them obviously undetectable with gift-day telescopes.
But that's not what observations showcase,compared dimensions and brightness of about a thousand nearby and vastly a ways away galaxies. They selected the most luminous spiral galaxies for comparisons, matching the natural luminosity of the close and some distance samples.
Opposite to the prediction of the enormous Bang idea, they determined that the skin brightnesses of the close and far galaxies are same
These outcome are constant with what may also be anticipated from original geometry if the Universe was no longer expanding, and are in contradiction with the drastic dimming of surface brightness expected by means of the expanding Universe speculation.
Of direction, that you would be capable to hypothesize that galaxies had been a lot smaller, and as a consequence had 1000s of instances larger intrinsic floor brightness prior to now, and that, simply by the use of accident, the massive Bang dimming exactly cancels that larger brightness in any respect distances to provide the illusion of a steady brightness, however that maybe a very giant accident. Special luminosity of the galaxies, in an effort to match close and far galaxies
to do this, the astrophysicists wanted to hyperlink the space to the galaxies with their redshift. They hypothesized that the gap is proportional to the redshift at all distances, as is good established to be the case inside the nearby Universe.
They checked this relation between redshift and distance with the info on supernova brightness that has been used to measure the hypothesized accelerated development of the Universe.
It's powerful that the predictions of this straightforward procedure are as just right as the predictions of the growing Universe concept, which comprise tricky corrections for hypothetical darkish subject and darkish vigour. once more you may take this to be clearly coincidental, nonetheless it might be a second significant coincidence.As a result if the Universe simply isn't growing, the redshift of sunshine with increasing distance must be brought about through every different phenomena something that happens to the sunshine itself because it travels via apartment.
We are not speculating now as to what might purpose the redshift of sunshine,
However, this sort of redshift, which is not related to expansion, could be found out with suitable spacecraft inside our possess solar approach in the future.

okay let's for a while think that universe is expanding then it is not necessary that atoms will grow.
