In summary, the conversation discusses the concept of space and time being quantized in the Planck length and Planck time. While the OP's astronomy professor believes in this theory, there is no concrete evidence to prove it. The significance of the Planck length and Planck time is that it requires a quantum theory of gravity to fully understand physics at these scales. The professor's training level is questioned, but it is later revealed that he is a full professor. There is only one proposed experiment to support the quantization of time, but it is facing funding delays. The conversation concludes with a reminder that arguing with a third party through the OP is not productive.

has it been proven that space and time are quantized in the Planck length and Planck time?

No. not at all.

my astronomy professor said that space and time are quantized.. the thing is.. i'd like to think that he wasn't talking out of his rear no offense to him at all. but i just don't see anyone else agreeing with him, which is why I'm asking

but if they aren't proven to be true, what ARE they? are they theorized fundamental units of space and time?

The significance of the Planck length and Planck time is that to understand physics at these length and time scales, we will need a quantum theory of gravity.

There are a lot of people that agree with him, but there are not any experiments that do (or that disagree). What is his level of training?

what do you mean? he's a full professor.

I didn't know if he was just a lecturer or something. I am not an expert, but the last I heard there was only one proposed experiment to show that time is quantized and the funding was slow. I don't remember who, it was. I'll see if I can any info.

This question was answered in message #2. "But someone else said..." is not an acceptable counter-argument here, I'm afraid. There's no point in us arguing with a third party through the OP.
 

FAQ: Have the planck scales been proven to be true?

What are the Planck scales?

The Planck scales are a set of fundamental units of measurement that represent the smallest possible scales in the universe. They include the Planck length, Planck time, Planck mass, and Planck energy.

How were the Planck scales determined?

The Planck scales were originally derived from fundamental physical constants such as the speed of light, gravitational constant, and Planck's constant. They are also supported by theoretical models such as quantum mechanics and general relativity.

Have the Planck scales been proven to be true?

No, the Planck scales have not been proven to be true. They are currently considered to be the smallest possible scales in the universe based on existing theories and observations, but they have not been conclusively proven.

Can the Planck scales be measured?

At this time, the Planck scales are too small to be measured directly with current technology. However, scientists are working on developing new technologies and experiments that may one day be able to measure these scales.

What implications do the Planck scales have for our understanding of the universe?

The Planck scales have significant implications for our understanding of the universe, particularly in the areas of quantum mechanics and general relativity. They also suggest that there may be a fundamental limit to how small and how large objects can be in the universe.
