Relativistic energy and matter

[Zelos]

all speed are relative to the observer, but if we have 2 planets with inteligent beings and for one of them all the objects in the universe seem to move just a bit slower than the other planet, wouldn't it then be less matter and energy in thge universe for those biengs? and with finite amount of matter and galaxies it must exist somewhere where its like that.

(note this is some fast thoughts that flow through my brain, i didnt think it trough so muchy but i want to hear what u guys say)

one of them all the objects in the universe seem to move just a bit slower than the other planet,

This is hard to imagine unless everything in the universe was moving in the same direction. However why should this difference in observed mass be a problem?

The concept of relativistic energy and matter is a fundamental principle in the field of physics. It states that all physical laws and measurements are relative to the observer's frame of reference. This means that the perception of speed, time, and distance can vary for different observers depending on their relative motion.

In regards to your question about two planets with intelligent beings and their perception of the universe, it is important to understand that the amount of matter and energy in the universe remains constant. It is the perception of these objects that may differ due to the relative speeds of the observers.

For the beings on the planet where everything appears to move slower, they would not necessarily have less matter and energy in their universe. It is just their perception that is different. From their perspective, objects may appear to have lower speeds and less energy, but in reality, the amount of matter and energy remains the same.

Additionally, the concept of a finite amount of matter and galaxies in the universe is still a topic of ongoing research and debate in the scientific community. While it is currently believed that the universe is expanding and contains a finite amount of matter, there are also theories that suggest the possibility of a multiverse or infinite universe.

In conclusion, the concept of relativistic energy and matter highlights the importance of considering the observer's frame of reference in understanding the physical world. And while the perception of matter and energy may vary for different observers, the fundamental principles of the universe, including the conservation of matter and energy, remain constant.
