The cooling temperatures 360,000 years after the big bang.
No, the growth of the universe is caused by the galaxies moving away from each other, with no relation to their size.
In fact, galaxies have an enormous mass.In fact, galaxies have an enormous mass.In fact, galaxies have an enormous mass.In fact, galaxies have an enormous mass.
Galaxies began forming around 13.6 billion years ago, not long after the Big Bang that created the universe. Over time, gravity caused matter to clump together, eventually forming the galaxies we observe today.
Yes ...why.. well there is a theory that once the universe was as small as a match's red head? i don't know what it's called what ever...so when that bead explodes and it expands. and scientists believe that it keeps expanding. Another question you should ask your self is if that the universe was that small what was around it? answer it cause i wanna know and hope this helps!
Edwin Hubble compared the distances to galaxies (based on their brightness) and their redshifts (due to the Doppler effect) to discover the expansion of the Universe. By finding a relationship between these two quantities (dubbed Hubble's Law), he provided evidence that the Universe is expanding.
None, the universe came into existence in the Big Bang very slightly spinning and every part of the universe is spinning. When a cloud of matter collapses to form galaxies, stars, solar systems, planets, etc. the local rate of spin increases. This not only makes the bodies themselves spin but it makes planets orbit stars in solar systems, stars and solar systems orbit inside galaxies, galaxies orbiting clusters of galaxies, etc.
Mutual attraction on macro scales such as stars, planets, and galaxies, is caused by gravity. Gravity can be better stated as the geometric shape on the macro scale of the universe, which is shaped and formed by the energy-momentum in the universe.
The evidence for Hubble's Law, which shows the relationship between distance and recession velocity of galaxies, was collected through observing the redshift of light from galaxies. Astronomers used spectroscopy to measure the redshift of galaxies, which is caused by the Doppler effect as the galaxies move away from us. By studying the redshift of galaxies at different distances, astronomers were able to support the idea that the universe is expanding.
The expansion of the Universe results in the light from faraway galaxies being redshifted. This is called the "cosmological redshift"; it can be compared with the Doppler effect (which also causes a redshift), but the details are somewhat difference.It is an observed fact that most galaxies are redshifted; the explanation that seems most reasonable is that it is caused by the cosmological redshift. This means that space itself is expanding.
Galaxies and planets are thought to have formed from the gravitational collapse of vast clouds of gas and dust in space. Within these clouds, gravity caused the material to clump together, eventually leading to the formation of galaxies composed of billions of stars and planets within these galaxies.
Gravitation.
Distance at cosmological scales is typically measured using the redshift of light from distant galaxies. This redshift is caused by the expansion of the universe, with more distant galaxies exhibiting higher redshifts. By measuring the redshift of galaxies, astronomers can calculate the distance based on the way that light is stretched as the universe expands.
