How big can an animal get? Science fiction frequently shows animals of enormous size, and yet in reality land mammals can only get so big. The amount of oxygen in the air, the type of muscle development needed to run, the limitations of reproduction by live birth, and a host of other technical problems are involved in limiting the size of land mammals. This is not just true of mammals, but it is true of birds which are also warm-blooded. Reptiles, on the other hand, never stop growing. An 80-year-old T. Rex was still growing, but I can tell you from personal experience that an 80-year-old man is not. This issue has a lot to do with whether the dinosaurs were birds, and whether dinosaurs and humans could have lived at the same time.
Every time some unusual signal from space is discovered, we see headlines in newspapers about aliens being the source of the signal. In August of 2016, reports came out of a radio telescope in Russia known as the RATAN-600 that had picked up a strong signal in the 11 gigahertz band. This was coming from a star known as HD 164595 and was first detected in 2013. Since that time the RATAN telescope and SETI have listened for repeat signals, but none have been detected. Headlines in the media have been things like “Baffling Alien Signal Detected.” Dr. Eric Korpela who works with SETI says, “There’s always the problem that scientific vocabulary is different from the public vocabulary. Detection, to me, means something was detected. To the public, it may translate as ‘We found aliens.’” It turns out that the signals have several possible natural explanations, none of which involve aliens.
The question remains as to why the public is so obsessed with the theme of aliens. We have pointed out repeatedly that finding life in space doesn’t have anything to do with the existence of God. If God chose to create life in other places for reasons we don’t fully understand, that is no issue. The Bible deals with humans and our existence on Earth. It is becoming obvious that there are no higher forms of life anywhere close to us, so the question is moot. This is not a question that has implications for the existence of God or the credibility of the Bible.
Let me introduce you to an animal that lives in the Arctic Ocean, spending much of its time under the pack ice. This animal has a refined sonar that is so intense and so directional that it can narrow or widen the sonar beam to find prey over short and long distances. The sound beams are asymmetric, narrowing on the top which minimizes noise clutter coming from the surface of the ocean or from the pack ice it swims under.
This is the most sophisticated sonar observed in a living species, and the animal that possesses it is the narwhal. The mechanism that generates the sonar is like that of a porpoise with clicks being emitted by the animal. The narwhal can do things that no other animal can do. Because narwhals can scan vertically as they dive, they always know where open patches of water exist so they can get back to a place where they can breathe.
In 1931 a Belgian astronomer named Georges Lemaitre proposed that the universe emerged from the decay of a single supermassive particle which he called “The Primeval Atom.” Since that time there have been a variety of similar explanations with the “Cosmic Egg” proposal being popular in the 1950s. The Big Bang was a label conceived by Fredrick Hoyle as measurements of the temperatures of various regions of space became known, and as radiation from the start of the cosmos confirmed a very hot singularity at the beginning of the cosmos. Hoyle’s label was actually making fun of some of the theories of his day, but the label stuck.
As more and more data has become available, the evolution of thought about the origin of the cosmos has changed. Quantum mechanics is now suggesting a whole new physics to describe the creation. While this has been happening, the evolution of words and their meaning has also taken place. A “singularity” is no longer understood as a point in space and time. It is not a single particle or kind of object. It is a condition of the cosmos in which space and time came into existence, containing ultra-hot and ultra-dense particles. The current theory says that a trillionth of a second after the singularity came into existence the temperature was a billion times hotter than the core of the Sun, and the energy density was more than 10 to the 36th power kilograms (that’s 10 followed by 36 zeros) in every cubic meter of space. To make it that dense, you would have to compress the Sun to the size of a marble.
Jeremiah 10:12 is typical of the descriptions the Bible gives of God’s creative acts. “He has made the earth by his power, he established the world by his wisdom, and has stretched out the heavens by his discretion.” Just as physics now turns to quantum mechanics to comprehend processes at a subatomic level beyond what we can physically see with our eyes, so too does the Bible describe God not in human terms, but in multidimensional terms. Acts 17:28 is a good example with the description of God being totally non-anthropomorphic, “In him we live and move and have our being.” Other passages such as Jeremiah 23:23-24 and 2 Chronicles 2:6 give a similar view of the nature of God as a being outside space and time.
