(#4) Time Is Literally Running Out
While some scientists believe the expansion of the universe is accelerating, some theorize that distant celestial bodies only seem that way because we're looking back in time to see them (remember, it takes a while for their light to reach us). So, that means that they were moving faster in the past than they are in now... which means time is slowing down.
How much is it slowing down? We don't know - but if the theory is correct it may just slow to a stop. -
(#1) The First Thing Aliens Will See From Humanity Is Hitler
Carl Sagan was a visionary man, gracing the world with his intelligence and imagination. In his book Contact, he theorized that the first thing aliens would see of us was Hitler. Turns out that the first signal broadcast powerful enough to break past Earth's atmosphere was Hitler's opening speech at the 1936 Olympics in Berlin, so there's a good chance that's the first communication aliens would pick up. Hopefully they won't judge us too harshly... -
(#6) Before the Big Bang, There Was Nothing
Yup. Literally nothing. According to Stephen Hawking, if this were true, the universe "would be neither created nor destroyed. It would just be." The creepy part: if there was nothing before the Big Bang, how long did it last before the universe started? And you thought it was tough waiting between seasons of your favorite shows... -
(#10) The Big Bang Came from Already-Existing Universes
String theory says that there shouldn't be just one universe, but a whole lot of them floating out there. How was ours crafted? Well, speculation is that the Big Bang came from other universes splitting apart or crashing together. Does it make us less unique? Sure. But look on the bright side - if that's true, that means we're not as alone as we thought. -
(#7) White Holes Are Apparently a Thing
Everyone knows about black holes, but apparently their opposites exist. Unlike their darker cousins, white holes cannot be entered, but matter and light are constantly escaping from them. The real creepy part is, where is all this stuff coming from? Could it be the exit of a black hole? -
(#13) There's an Equation for How Alone We Are in the Universe
Dr. Frank Drake wanted to know how many extraterrestrial civilizations we could possibly communicate with, so in 1961 he wrote the Drake Equation, which estimates the number of civilizations with which we could possibly make contact. The equation itself has come under scrutiny for using "educated guesses" as parameters, so it's impossible to get an accurate measurement.

About This Tool
Humans have a long history of thinking and studying the universe. According to the huge explosion theory that many scientists have consistently supported for centuries, our universe was born about 14 billion years ago. According to the explanation of this theory, the universe was formed 14 billion years ago by the explosion of extremely small and dense matter, and it was from then that time and space, mass, and energy began to be produced.
The exploration of the universe is an extremely complex issue. The universe is a material world, and it is in constant movement and development. The random tool lists 13 interesting theories about the universe that prove the exploration of the universe has never stopped.
