Will a black hole hit Earth?
There are no black holes close enough to Earth to affect us.
This black hole is 6.6 times more massive than our Sun.
(That means it has a lot of mass, which means it has a really strong gravitational pull – much stronger than even our Sun’s gravitational pull.).
Is it possible to go back in time?
The Short Answer: Although humans can’t hop into a time machine and go back in time, we do know that clocks on airplanes and satellites travel at a different speed than those on Earth. That kind of time travel sounds like something you’d only see in movies or science fiction books. …
How long till the universe ends?
Some astronomers estimate this could happen as soon as 1 trillion years from now. Either way, both scenarios leave us with a universe where no light or life will ever exist, again.
Will the universe be reborn?
The universe could bounce through its own demise and emerge unscathed. A new “big bounce” model shows how the universe could shrink to a point and grow again, using just the cosmic ingredients we know about now.
What does space smell like?
Astronaut Thomas Jones said it “carries a distinct odor of ozone, a faint acrid smell…a little like gunpowder, sulfurous.” Tony Antonelli, another space-walker, said space “definitely has a smell that’s different than anything else.” A gentleman named Don Pettit was a bit more verbose on the topic: “Each time, when I …
Where does space end and heaven begin?
Karman lineSo where does Earth stop and the heavens start? According to a paper that was published in the Journal of Geophysical Research-Space Physics, the border between the two—the so-called Karman line—sits 73.2 miles (188 kilometers) above Earth’s surface.
Can humans survive the heat death of the universe?
The heat death of the universe refers to a state of maximum entropy, a condition under which no processes can occur. If there are still humans, then the universe has not yet reached heat death. So, no, by definition we cannot survive the heath death of the universe. … Entropy must increase to do work.
What lies at the end of the universe?
So, in some ways, infinity makes sense. But “infinity” means that, beyond the observable universe, you won’t just find more planets and stars and other forms of material…you will eventually find every possible thing.
Does time have an end?
“Time is unlikely to end in our lifetime, but there is a 50% chance that time will end within the next 3.7 billion years,” they say. That’s not so long! It means that the end of the time is likely to happen within the lifetime of the Earth and the Sun. … At least, not for another 3.7 billion years.
Can you exit the universe?
If the Universe is flat and expanding at the speed of light, that must mean that we could never leave it, because one would have to travel faster than the speed of light which is not possible. … The distance is less and if the Universe is not expanding in depth but only sideways then it would be possible to exit.
Where does space end?
No, they don’t believe there’s an end to space. However, we can only see a certain volume of all that’s out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn’t had time to reach us yet, so we have no way of knowing such a galaxy exists.
Who died on the moon?

Who creates God?
Defenders of religion have countered that the question is improper: We ask, “If all things have a creator, then who created God?” Actually, only created things have a creator, so it’s improper to lump God with his creation. God has revealed himself to us in the Bible as having always existed.
Does space have a smell?
As it turns out, space actually does have a distinct odor. … Astronauts returning from space claim that their suits smell, in a word, burnt. The lingering scent of space is “acrid” and “metallic,” reminding the astronauts of charred meat or welding fumes.
Do things exist when not observed?
An item truly exists only as long as it is observed; otherwise, it is not only meaningless but simply nonexistent. The observer and the observed are one.
