a few hundred thousand years after the Big Bang
Scientists using the earliest microscopes observed tiny organisms such as bacteria and protozoa for the first time. They also discovered that cells were the basic unit of living organisms, leading to the development of cell theory.
The Big Bang theory suggests that all matter, energy, space, and time were created during the initial explosion. This event led to the expansion of the universe, with particles forming and eventually evolving into stars, galaxies, and the vast cosmic structures we observe today.
The ability for space to expand is crucial for our understanding of the universe and its evolution. It allows for the formation of galaxies, stars, and planets, shaping the cosmic structure we observe today. This expansion also provides insights into fundamental physics, including the behavior of dark energy and the fate of the universe. Ultimately, a dynamic universe enriches our knowledge and challenges our perceptions of time and space.
The sky refers to the atmosphere above the Earth where clouds, the sun, moon, stars, and other celestial objects are visible. The universe, on the other hand, encompasses all matter, energy, space, and time, including galaxies, stars, planets, and all cosmic structures. The sky is a small part of the universe that we can observe from Earth.
After they hit the ground.
no it didn't because i think they are the same because time did not change
Astronomical phenomena like galaxies or the entire universe are too big to observe entirely. Subatomic particles like quarks are too small to observe directly. High-speed subatomic processes or events like the decay of certain particles may occur too fast to observe, while geological processes like tectonic plate movement may be too slow to observe in real-time.
The universe is the term used to describe all of space, time, matter, and energy that exists. It includes planets, stars, galaxies, and everything that we can observe or detect through scientific methods.

People would look at the position of the sun and depending on where it was in the sky, they would know what time it was. For example, if the sun was directly above it was midday.
Earliest Available Time or Earliest Arrival Time
Samoa Island has the earliest time in the world.
The earliest time mid March in spring

The Big Bang suggests that the universe is Time bound (or has a finite existence), that the universe is expanding (within the dimensional limits of Space and Time), that the universe is evolving a set amount of matter and energy while it is expanding over time, and that the universe is homogeneous and isotropic with respect to Space and Time.
earliest occurence time in event
The Milky Way is our galaxy, the galaxy that contains our solar system and almost all of the objects we observe in our sky. At the time of the theorized 'big bang', the very beginning of our universe, there were no galaxies and no stars in existence. That all came much later.
