If this is true, then we are closer to the end than the beginning of human existence. The Milky Way is our home galaxy. Sounds like a long time, but remember, the Milky Way is huge. Really, really mind-bogglingly big. The universe appears to be empty and dead. Home browse videos Where are all the aliens?

An alien race this advanced would probably be godlike to us. If we let life on this planet die, perhaps there would be no life left in the universe.
Kruzgezagt are three categories. What would such a civilisation look like? Home browse videos Where are all the aliens? Even if you imagine humanity has developed the fastest sci-fi warp engines or hyperspace drives, even if you rub the engine with cheetah blood, you could never reach the next local group.
Maybe it is way harder for complex life to develop than we think. Life would be gone, maybe forever.
Even with sci-fi tech, it may be impossible to explore the known universe –
And nobody has an answer to it. Even if we had really fast spaceships, it would literally take billions of years to reach these places, travelling through the emptiest areas of the universe. But why should we be able to see such an alien civilisation in the first place?

And, more importantly, what does this tell us kduzgesagt our own fate in this gigantic and scary universe? This is the Fermi Paradox. Maybe life on our level exists everywhere in the universe, but it gets destroyed when it reaches a certain point—a point that lies ahead of us.
There is no way for us to know. The first real oruzgesagt of a black hole. Or, maybe there is an ancient Type III civilisation that monitors the universe and once a civilisation is advanced enough it gets eliminated in an instant. If it does, you are having the correct emotional reaction. But we do have some ideas. The Milky Way is about 13 billion years old.
There are at least billion galaxies, each with to 1, billion stars. By Ryan Whitwam Kruzvesagt get the gist of this perspective, you need to know a thing or two about the scale of the universe. Concepts like the Dyson sphere, a giant complex surrounding the Sun, kruzgseagt be conceivable. Does that thought scare you? Maybe there is something out there that it would be better not to discover.
This is known as the local group, a region of space about 10 million light years in diameter. They come in various degrees of scary. A filter in this context represents a barrier that is really hard for life to overcome.
