Big bang

In summary, the high density at the Big Bang moment according to LQC was caused by the prior collapse, and the large but finite density that was achieved can be calculated within the context of the LQC bounce model.

Planck launch will be a big event for many reasons. I foresee it as one of the most important experiments ever conducted. Let's wait a month or three and see what it reveals. I expect mostly the expected, and a few very unexpected results. The Herschel will also be launched on this mission. See the NASA site for details. We live in exciting times. This is the golden age of science. We've already seen WMAP and gravity probe B, and it keeps getting better. Imagine what we could do if we did a better job averting indulgence in needless conflicts.

1. What was there before the Big Bang?

This is a question that has puzzled scientists for decades. The truth is, we don't know for sure what existed before the Big Bang. Some theories suggest that there was a singularity, a point of infinite density and temperature, while others propose the existence of a multiverse. Ultimately, the answer is still a mystery.

2. Was there time before the Big Bang?

Time as we know it is a product of the Big Bang. This means that there was no time before the Big Bang. The concept of time only came into existence after the expansion of the universe began. However, some theories suggest that time may have existed in a different form before the Big Bang.

3. What caused the Big Bang?

This is a question that scientists are still trying to answer. The Big Bang theory suggests that the universe began as a singularity, a point of infinite density and temperature, and expanded rapidly. However, the cause of this initial singularity is still unknown. Some theories propose the existence of a multiverse or a collision between two branes in a higher-dimensional space.

4. What happened during the Big Bang?

During the Big Bang, the universe rapidly expanded and cooled, allowing for the formation of matter and energy. This process is known as cosmic inflation. As the universe continued to expand, matter and energy clumped together to form galaxies, stars, and planets. This process is still ongoing today.

5. Can we ever know what happened before the Big Bang?

As of now, we do not have the technology or understanding to fully comprehend what happened before the Big Bang. However, scientists continue to study the early stages of the universe and try to piece together the events that led to the Big Bang. With advancements in technology and new theories, we may one day have a better understanding of what occurred before the Big Bang.
