  • The Big Splat. Artist’s impression of multiple braneworlds.
  • Plasma-filled cosmos.
  • The holographic universe.
  • The steady-state universe.
  • The multiverse.
  • We got gravity wrong.
  • Superfluid space-time.

Is all existing matter part of the universe?

The universe (Latin: universus) is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy.

Is there any real image of atom?

Physicist: Actual pictures of atoms aren’t actually pictures at all. But the wavelength of visible light is about half a micrometer (a two-millionth of a meter) and atoms are around one ångström (a ten-billionth of a meter) across. On the scale of atoms, visible light acts too wonky to be used for photographs.

Are solar systems like atoms?

The Bohr or solar system model of the atom states that atoms consist of a nucleus with a number of electrons in orbits around that nucleus, similar to a solar system. Perhaps our own Solar System is similar to the element Oxygen, which has a nucleus and eight smaller electrons rotating around it in their orbits.

What are the different theories on the end of the universe?

Theories about the end of the universe. The fate of the universe is determined by its density. The preponderance of evidence to date, based on measurements of the rate of expansion and the mass density, favors a universe that will continue to expand indefinitely, resulting in the “Big Freeze” scenario below.

Could there be an atom inside another universe?

Another reason why the universe could never be an atom inside another universe is quantum mechanics. According to quantum mechanics, the electrons in an atom are not on one specific position, but they are everywhere around the nucleus at the same time]

Does the universe have a center of matter?

The universe of course doesn’t have most of its matter centered in the “middle” but rather has fairly spread out mass. However, if you are referring to the fact that most of the atom’s space is empty being similar to the universe then you are correct. The universe also has a huge amount of empty space between stars and galaxies.

How did the universe become the lumpy entity we see today?

Radiation burst out in every direction, and the Universe was on its way to becoming the lumpy entity we see today, with vast swaths of empty space punctuated by clumps of particles, dust, stars, black holes, galaxies, radiation, and other forms of matter and energy.

Could the universe have had a bounce instead of a bang?

With a bounce rather than a bang, Steinhardt says, distant parts of the cosmos would have plenty of time to interact with each other, and to form a single smooth universe in which the sources of CMB radiation would have had a chance to even out. In fact, it’s possible that time has existed forever.
