Recently, a new study suggests that the darkening of Sensual IV may not have been simply a dust cloud, as it is suspected to have been pierced by a mysterious force before the darkening of Sensual IV

The reason we don't see time travelers is actually because they are not in our timeline

If we make the space station in space into a ring and let it rotate, then the humans in it will also feel the "centrifugal force" to "push" themselves towards the outer wall of the space station

The universe is so unimaginably large that even if humans were able to travel at infinitely close to the speed of light, they would not be able to penetrate its mysteries. Fortunately, the speed of light is not the speed limit of the universe, so it is entirely conceivable that in the distant future, humans may somehow be able to escape the shackles of the speed of light.

It has long been discovered in practice that the phenomenon of "gravitational time dilation" does exist

The energy released by nuclear fusion is actually an important basis for stars to be able to maintain their stability

Below the solar system, there is a star system labeled "alpha Centauri".

Although the Earth is just a "grain of dust suspended in the sun" in the universe, for us humans, this "grain of dust" is irreplaceable.

Further research shows that this mysterious force accounts for 68.3% of the total mass energy of the universe, and it is because of this that it is able to overcome gravity and become the dominant force controlling the operation of the universe

Intelligent life is rare in the universe, or perhaps it is just wishful thinking on our part. As mentioned earlier, just in the galaxy, there are hundreds of millions of planets that have the natural conditions to nurture life, so a reasonable speculation is that life has evolved on many planets, and even a number of planets have evolved intelligent life.
