Could we be in a black hole?
A black hole is an object so dense that not even light can escape it.
Some researchers believe the universe emerged from the collapse of a star in a very different reality with five dimensions, meaning our reality was created by a black hole which we could still be living inside..
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.
Does the universe has an end?
As the energy density, scale factor and expansion rate become infinite the universe ends as what is effectively a singularity.
Which country is the end of Earth?
NorwayVerdens Ende (“World’s End”, or “The End of the Earth” in Norwegian) is located at the southernmost tip of the island of Tjøme in Færder municipality, Norway.
How long will it take for the universe to end?
Vacuum decay might already have begun in some distant place. We won’t see it coming. Not to worry, though. As Mack counsels, whatever it looks like, the end probably won’t be nigh for at least 200 billion years.
Who died on the moon?

What is inside a black hole?
A black hole is a tremendous amount of matter crammed into a very small — in fact, zero — amount of space. The result is a powerful gravitational pull, from which not even light can escape — and, therefore, we have no information or insight as to what life is like inside.
What is there at the end of space?
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.
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 …
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.
Are there any dead bodies in space?
As of 2020, there have been 15 astronaut and 4 cosmonaut fatalities during spaceflight. Astronauts have also died while training for space missions, such as the Apollo 1 launch pad fire which killed an entire crew of three. There have also been some non-astronaut fatalities during spaceflight-related activities.
How does space go on forever?
In theory space goes on and on… So why do scientists think that space goes on forever? It’s because of the shape of space. Our part of space, or the observable universe, has a special shape: it is flat. … In fact, you would always stay exactly the same distance apart, within the observable universe.
Has a gun ever been fired in space?
Only after the fall of the USSR did Russian sources revealed that the cannon had actually fired in orbit. It happened on Jan. 24, 1975, onboard the Salyut-3 space station. … The outpost ignited its jet thrusters simultaneously with firing the cannon to counteract the weapon’s powerful recoil.
Can you reach the edge of the universe?
There is no evidence that the universe has an edge. The part of the universe we can observe from Earth is filled more or less uniformly with galaxies extending in every direction as far as we can see – more than 10 billion light-years, or about 6 billion trillion miles.
How far is it to the end of space?
46.1 billion light-yearsIf you define it as the limit of what we can observe a signal from — who we can see and who can see us — then the edge goes out to 46.1 billion light-years.
Would a body decay in space?
If you do die in space, your body will not decompose in the normal way, since there is no oxygen. If you were near a source of heat, your body would mummify; if you were not, it would freeze. If your body was sealed in a space suit, it would decompose, but only for as long as the oxygen lasted.
How many heavens are there according to science?
seven heavensIn religious or mythological cosmology, the seven heavens refer to seven levels or divisions of the Heavens (Heaven). The concept, also found in the ancient Mesopotamian religions, can be found in Judaism, Christianity, and Islam; a similar concept is also found in some Indian religions such as Hinduism.
How cold is space?
Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that, at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit).
