A century after Hubble's discovery, our neighbor galaxies suggest a creator's mind
(Reuters) — When you gaze up at the night sky, the unaided eye can only discern about 2,500 to 3,000 stars, five planets, and perhaps one to three galaxies, assuming perfect atmospheric conditions and a suitable location. This has sufficed throughout human history to awe us with the vastness and wonder of what we can perceive.
About a century ago, astronomer Edwin P. Hubble (1889-1953), working at California's Mount Wilson Observatory, made an incredible find: He determined that the spiral nebula known as Andromeda was approximately 860,000 light-years away — more than eight times farther out than the most distant stars within our own galaxy. He eventually understood that what had been thought was either a gas cloud or a group of stars within the Milky Way was actually a separate galaxy, and that the Milky Way was merely one of many galaxies in the cosmos.
Hubble announced his discovery on December 30, 1924. We're commemorating that anniversary this week. Hubble went on to identify approximately 24 more galaxies.
Following these revelations, many more groundbreaking astronomical discoveries were made. We found out that our universe is much, much older than we previously thought, and it's actually still growing. In 1929, Hubble determined the rate at which the universe is expanding. He observed that galaxies farthest from us are moving away from us at incredible speeds. We also learned that the universe seems to have originated from a singular event, an explosion sometimes referred to as “the big bang.”
As our knowledge about the number of stars and galaxies has grown, so has our estimate of how many there actually are. In 1990, NASA launched the Hubble Space Telescope, which was put into space 353 miles away from Earth. The amazing photos from the Hubble astonished people everywhere. Based on the data it collected, astronomers initially believed that an average galaxy contains around 100 billion stars and that there are approximately 200 billion galaxies. However, recent assessments are suggesting that this initial estimate was significantly too low.
On December 25, 2021, the newest James Webb Space Telescope, which is currently the most powerful space telescope ever created, was launched. Located about 1,500,000 kilometers from Earth, it is designed to be able to detect infrared radiation, and it can see farther into space than the Hubble Telescope. It is now looking back in time at some of the most distant galaxies and stars that have ever been observed – exploring an area that astronomers refer to as "the cosmic dawn."
What do all these explorations tell us? Beyond the number of galaxies, they have revealed that the universe is much bigger than we ever thought, that it has a starting point, a moment of birth. At the same time, it appears to be somewhat orderly, in that it consistently follows the same principles.
The universe has incredibly complex structures. There are settings that are carefully balanced to support life. We reside in what some have referred to as “the Goldilocks zone”: an area around a type of star at the right distance from the sun, with the right rotational speed and the right axis tilt, with the right amount of water and the right atmosphere, all making it possible for human life to exist.
What do these incredible findings really mean? How did the universe develop into its current state? And why does the universe exist, rather than not exist at all?
some scientists suggest that the universe came into being as a result of a series of unrelated, unforeseen events. These theories, that the universe developed through random chemical reactions, portray the universe as a process without a guiding force, meaning, or purpose.
Not all such stories involve chance: In 2021, Harvard astrophysicist Avi Loeb, former head of the Harvard astronomy department, proposed the idea that our universe was created in a lab by aliens.
The multiverse hypothesis is a well-established philosophical concept, but since it can't be empirically tested, it doesn't fit squarely within the realm of scientific inquiry.
It seems that an increasing number of scientists and experts in astronomy, similar to Ellis himself, are now coming to the conclusion that the most reasonable explanation for a cosmos is that one requires a creator. The word "cosmos" itself comes from the Greek term κόσμος, and in English, we also get the term "cosmology" from it, which means a system of order and harmony. For this order to exist, it suggests the need for a designer.
Christian astrophysicist Hugh Ross notes that "the universe is extremely well-suited to support life, and this intricate balance of conditions strongly suggests a deliberate Creator. The more we discover about the universe, the more it matches the biblical portrayal of a creation wisely designed and carefully maintained.
Hubble himself did not make any claims about whether there was a creator, but the wonder and impact of his discoveries have encouraged others to revisit the idea of "the God hypothesis."
