2020年9月29日 · That’s how big our Universe is, and that’s not even the end of it. The 93 billion years is just the observable Universe, the Universe, which we can currently see. The whole Universe might very well be 250 times larger than the observable Universe, or at least 7 trillion light-years in diameter.

2023年8月22日 · The Big Bang event is a theory that exists in physics which describes a possible version of our universe expanding from an initial state of high density and temperature. The work of mathematicians and astronomers has combined for decades in trying to prove or disprove this theory based on our observable universe.

2020年8月19日 · The Universe has expanded since the Big Bang, monotonically. It is believed that our universe has the right mass-energy density, equivalent to around 5 protons per cubic meter, which allowed it to expand for the last 13.8 billion years.

2020年3月17日 · Ultimately, Hubble’s findings proved that our Milky Way was just one out of countless of other galaxies in a vastness of space called the Universe. This discovery was the beginning of the Big Bang theory. Hubble didn’t devise this thesis, but his findings influenced others to theorize upon the Universe’s creation. The Big Bang Theory

2020年9月29日 · It’s just a matter of time until we will reclassify our Sun as being below average- in terms of size. How Big is Betelgeuse Compared to the Sun? Betelgeuse, like the other stars mentioned above, is among the biggest stars in our Universe that we know of at least. This supergiant red star has between 950 and 1,200 solar radii, or it has ...

2023年8月22日 · Well the Big Bang is a theoretical event that exists in physics which describes a possible version of our universe expanding from an initial state of high density and temperature. The work of mathematicians and astronomers has combined for decades in trying to prove or disprove this theory based on our observable universe. The Outward Expansion ...

2020年9月29日 · The Earth is estimated to be 4.54 billion years old, so the Universe itself is, on average, around three times older than our Earth but only if the Universe is indeed 13.8 billion years old. Our galaxy, the Milky Way , might be a better comparison, as …

2023年10月31日 · The theoretical Big Bang event is a concept that exists in physics which describes a possible version of our universe expanding from an initial state of high density and temperature. The work of mathematicians and astronomers has combined for decades in trying to prove or disprove this theory based on our observable universe. Expanding Outwards ...

2019年11月5日 · They like to use our Sun to measure size. This means scientists like to place stars and suns next to our own Sun to see how these objects compare. The solar radius is 690,000 km and the mass is 4.3 x 10^30 pounds. Supergiant stars are the largest stars, and they are much larger than our own Sun.

2019年10月8日 · 2. How Big is Our Universe? (Astronomy and Cosmology) This course is specifically designed to explore the size and scope of our universe. Drawing from cosmological documentaries, the course closely examines black holes, microwave radiations, characteristics of the Solar System, and the formation of celestial bodies.
