He infinite universe has always fascinated humanity. Explore its curiosities of the cosmos It's exciting. From the big Bang, the universe has been growing non-stop, a process that has lasted at least 13.7 billion years¹.

This vast space overwhelms us with dimensions that we sometimes cannot understand. What we see in the universe is, in fact, the past. For example, seeing a star explode 100 light years away means that the event occurred 100 years ago.².

The galaxy UGC 2885 is one of the wonders of the cosmos. It has a radius of approximately 815,391 light years.². Also, the discovery of "hydrogen rivers" in the universe opens up new possibilities for star formation.²The Methuselah star, the oldest ever discovered, is about 14.5 billion years old, showing us unimaginable periods of the universe.².

The expansion of the universe makes visible space grow constantly. Its diameter is estimated at up to 100 billion light years¹I invite you to explore with me the mysteries of space and the vastness of the universe in which we live.

Key findings

• The universe is at least 13.7 billion years old according to current estimates.
• The expansion of the universe has been going on since big Bang.
• The observable universe extends about 46.5 billion light-years.
• The galaxy UGC 2885 is the largest known, reaching 815,391 light-years in radius.
• HD 140283, or Methuselah, is approximately 14.5 billion years old.

The vastness of the universe: is it really infinite?

The idea of whether the universe is infinite has intrigued many. It is thought to be about 13.799 billion years old.³Its diameter is at least 93 billion light years.³. Even though we try to understand its size, we will never know everything about it. This suggests that it could be infinite.

Space exploration has come a long way. Every new discovery helps us better understand the universe.⁴. The expansion of the universe It's like a balloon that inflates, which makes you think that it is very big and perhaps infinite.⁵The cosmic background radiation gives us clues about its shape and size, indicating that it could be flat or curved.⁵.

The idea of a finite universe is also intriguing. Theories like the Big Crunch say it could collapse⁴. But think of a infinite universe motivates us to continue exploring and discovering its secrets.

The origins of the universe: The Big Bang

He big Bang It is the most accepted theory about the origin of the universeIt is believed to have occurred about 13.797 billion years ago. This event marked the beginning of all matter and energy in the cosmos.⁶.

Georges Lemaître proposed this theory in 1927. He suggested that the universe began as a point that expanded⁷.

Since then, the universe has been growing non-stop. In 1929, Edwin Hubble observed that galaxies are moving away from each other. This confirmed that the universe is expanding.⁷.

Currently, the universe is estimated to be about 13.8 billion years old. This shows the progress of science in recent decades.⁷.

The cosmic microwave background radiation is a key evidence of the big Bang⁶. This discovery in 1964 allows us to study the first moments of the universe. Observations from the James Webb have revealed that some galaxies formed faster than expected. This has changed our view of the universe. cosmological theory⁸.

In conclusion, the big Bang not only explains the origin of the universe. It remains a topic of study and reflection in cosmology. Each discovery helps us better understand how the universe developed. In this way, we explore the complexity and richness of our cosmos.

Space Mysteries: The Wonders of the Cosmos

The expansion of the universe It is a fascinating subject. It started with the big Bang and shows how galaxies are moving away from each other. This suggests that the universe is constantly changing. Each study of this makes us wonder more about the mysteries of the cosmos.

The expansion of the universe

The idea that the universe is expanding is becoming clearer with new evidence. This discovery was unexpected. It has caused scientists to question many theories about the universe.

I love thinking about how these explorations can reveal new aspects about the universe. What will the creation and composition of the universe tell us?

The discovery of microwave background radiation

In 1965, the discovery was made microwave background radiationThis confirmed the Big Bang theory, showing evidence of residual energy. This radiation gives us clues about the composition and evolution of the universe.

I think that every step towards understanding this radiation brings us closer to unraveling the mysteries of the cosmos. It shows us in a surprising way what was previously incomprehensible.

Time and light: looking into the universe's past

When I look up at the night sky and see the stars, I think of light traveling through time. Einstein's theory says that light is the fastest. This means that what we see now is an echo of the past. For example, a star 100 light years away shows its history through the light that reaches us after a century.⁹.

The James Webb Space Telescope has changed the way we observe the universe. It has captured images of galaxies that witnessed the Big Bang. This gives us a unique view of how the universe evolved, showing a cosmos full of mysteries.¹⁰.

Understanding time in the universe is fascinating. Some theories say that time could go towards more complexity, not towards total entropy.⁹. Each observation shows us not only the past, but also future possibilities. This journey reminds us of “Carpe diem,” valuing every moment in our cosmic history.⁹.
