How could the big bang create time?

In summary, time began with the start of change in the universe, and it is impossible to determine if there was anything before the big bang.

If there was no time before the big bang then how did it happen and how could time be created if there was was nothing to make it?

Time and space are simply the measure of change. Something must change in space dimension before time can be marked off. If nothing ever changes, there is no time. So time starts when things in the universe started to change.

If the universe ever existed in a state where nothing changed, as a primordial atom, for example, then time did not exist then, and we can never know how long it existed in that state.
 

1. How do scientists explain the concept of time in relation to the big bang?

The concept of time in relation to the big bang is a complex and widely debated topic among scientists. Many theories suggest that time, along with space and matter, was created during the big bang. This means that the beginning of the universe marked the beginning of time. However, some theories propose that time existed before the big bang and was simply transformed during the event. Ultimately, the exact relationship between the big bang and time is still a subject of ongoing research and discovery.

2. Can the big bang theory explain the origin of time?

The big bang theory is the most widely accepted scientific explanation for the origin of the universe. While it does not explicitly explain the origin of time, it does propose that time, along with the rest of the universe, began at the moment of the big bang. As our understanding of the universe continues to evolve, it is possible that new theories may emerge that provide further insight into the origin of time.

3. How can something as complex as time be created from a single event like the big bang?

The big bang was not a simple or single event, but rather a complex and rapid expansion of matter and energy. During this expansion, the fundamental forces of the universe, such as gravity and electromagnetism, were also created. These forces play a critical role in the structure and behavior of the universe, including the concept of time. While it may seem difficult to comprehend, the big bang provides a plausible explanation for the creation of time as we know it.

4. Does the big bang theory suggest that time has a beginning and an end?

The big bang theory does not explicitly suggest that time has a beginning and an end. However, it does propose that time began at the moment of the big bang and has been continuously passing since then. Some theories suggest that time may eventually come to an end, while others propose that it will continue infinitely. The exact nature of time, including its potential beginning and end, is still a subject of ongoing scientific research and debate.

5. How does the big bang theory account for the concept of time dilation?

The concept of time dilation, as described by Einstein's theory of relativity, proposes that time can appear to pass at different rates for objects in different gravitational fields or traveling at different speeds. The big bang theory does not directly account for this phenomenon, but it does provide a framework for understanding the origins and behavior of the universe, including the forces that may influence time dilation. Further research and study of the big bang may provide additional insight into the concept of time dilation and its relationship to the origin of the universe.
