Dear students, many of you have asked me what my opinion is on the UAP and UFO phenomena, and I would like to answer you. According to say in an absolute sense that two distinct events occur at the same time if those events are separated in space. If one reference frame assigns precisely the same time to two events that are at different points in space, a reference frame that is moving relative to the first will generally assign different times to the two events (the only exception being when motion is exactly perpendicular to the line connecting the locations of both events).Entities develop at different times and places in time and space, so not in the same time and space planeThe concept that entities develop at different times and places means they don't necessarily exist or evolve within the same "space-time" plane. This idea is rooted in relativity, which shows that time and space are interwoven and relative to the observer's frame of reference. Essentially, events that appear simultaneous to one observer might not be simultaneous to another, especially if they are moving relative to each other. In physics, spacetime, also called the space-time continuum, is a mathematical model that fuses the three dimensions of space and the one dimension of time into a single four-dimensional continuum. Spacetime diagrams are useful in visualizing and understanding relativistic effects, such as how different observers perceive where and when events occur. In four-dimensional spacetime, the analog to distance is the interval. Although time comes in as a fourth dimension, it is treated differently than the spatial dimensions.The fundamental reason for merging space and time into spacetime is that space and time are separately not invariant, which is to say that, under the proper conditions, different observers will disagree on the length of time between two events or the distance between the two events . Special relativity provides a new invariant, called the spacetime interval, which combines distances in space and in time. All observers who measure the time and distance between any two events will end up computing the same spacetime interval. The chance of it happening is smaller than the score being accurate. I'll win the lottery sooner. Unknown data transmission medium, unknown encoding, unknown language. We are not even able to decipher the language of mammals living on Earth. Despite advanced radio telescopes and increasingly sophisticated SETI methods, it is possible that terrestrial technology is simply not sensitive enough, or is flying blind. Signals emitted by distant civilizations may be too faint or on a platform unknown to us, to distinguish them from the cosmic background noise. Current contact techniques may not be suitable for detecting the most diverse, even completely unknown, forms of alien communication. Moreover, our modern instrumentation examines a relatively narrow wavelength range, so it is possible that aliens may send information in a completely different range. The different time scales, even if advanced extraterrestrials existed, may have already become extinct or are only now evolving. The galactic time scale is enormous: what is millions of years to us, is mere moments to individual star systems. It may be that alien civilizations that flourished in the past no longer exist, only their remains carried by space, which we have not yet been able to interpret. The signals from the past slowly fade, and by the time we would detect them, the sender may have long since disappeared from the stage of the cosmos. Since we are not intelligent beings, their deliberate silence is possible, it is possible that advanced aliens consciously avoid contact with other species. Perhaps they are guided by caution, since an encounter with a possible aggressive civilization could be dangerous. Thus, it is possible that we do not detect signals because they do not want to send a message. This kind of "galactic silence" may be a kind of self-defense strategy on their part. Different forms of communication: Extraterrestrials may not use radio waves, light pulses, or any form of communication that we know of. That is why UFO research does not only focus on classic radio signals, but also tries to identify strange, atypical phenomena that may be of alien origin. It is conceivable that aliens use advanced technologies that our current instruments cannot handle. In addition, the possibility arises that communication takes place in a multidimensional network, where the concept of space and time is incomprehensibly different for us, so that contact with aliens is not a linear, wavelength-based phenomenon, but is based on something completely new, unknown to us.
