What’s inside a black hole?

At the center of a black hole, it is often postulated there is something called a gravitational singularity, or singularity. This is where gravity and density are infinite and space-time extends into infinity. Just what the physics is like at this point in the black hole no one can say for sure.

Can a wormhole exist?

Einstein’s theory of general relativity mathematically predicts the existence of wormholes, but none have been discovered to date. A negative mass wormhole might be spotted by the way its gravity affects light that passes by.

Is there a white hole?

White holes are theoretical cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole, nothing can enter a white hole. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.

Are black holes hot?

Black holes are freezing cold on the inside, but incredibly hot just outside. The internal temperature of a black hole with the mass of our Sun is around one-millionth of a degree above absolute zero.

Is absolute zero Possible?

Absolute zero, technically known as zero kelvins, equals −273.15 degrees Celsius, or -459.67 Fahrenheit, and marks the spot on the thermometer where a system reaches its lowest possible energy, or thermal motion. There’s a catch, though: absolute zero is impossible to reach.

What if you fell into a black hole?

Your body would be stretched apart. The most common black holes are called “stellar”. They can stretch to about 9 miles (15 km) across and be as heavy as 20 suns. If you happened to be pulled towards a stellar black hole, you’d be completely torn apart before you even reach the event horizon.

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).





How long is 1 hour in space?

One hour on Earth is 0.0026 seconds in space.

What happens if you bleed in space?

In space, blood can splatter even more than it usually does on Earth, unconstrained by gravity. Or it can pool into a kind of dome around a wound or incision, making it hard to see the actual trauma. (Fun fact: If you are bleeding more than 100 milliliters per minute, you are probably doomed.

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 …

Can you fart in space?

Surprisingly, that isn’t the biggest problem associated with farting in space. Though you’re definitely more likely to worsen a small fire when you fart, it won’t always injure or kill you. The worst part about farting in space is the lack of airflow. Let’s take a step back and remember how farting on Earth works.

Does color exist in space?

Read on to learn more about color in space. Believe it or not the human eye can see about 7,00,000,000 colors. But, did you know that colors exist that you cannot see? Color does not change in space, because the wavelengths remain the same.





Does space have a end?

Scientists now consider it unlikely the universe has an end – a region where the galaxies stop or where there would be a barrier of some kind marking the end of space.

Where does the earth end?

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. Needless to say, Earth’s atmosphere is pretty thick, which is a good thing.

Is time Travelling possible?

In Summary: Yes, time travel is indeed a real thing. But it’s not quite what you’ve probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second.

Does the past still exist?

In short, space-time would contain the entire history of reality, with each past, present or future event occupying a clearly determined place in it, from the very beginning and for ever. The past would therefore still exist, just as the future already exists, but somewhere other than where we are now present.





How is time an illusion?

According to theoretical physicist Carlo Rovelli, time is an illusion: our naive perception of its flow doesn’t correspond to physical reality. Indeed, as Rovelli argues in The Order of Time, much more is illusory, including Isaac Newton’s picture of a universally ticking clock.

Can I go back to the past?

The urge to hug a departed loved one again or prevent atrocities are among the compelling reasons that keep the notion of time travel alive in the minds of many. While the idea makes for great fiction, some scientists now say traveling to the past is impossible.

Has a time machine been invented?

In fact, a time machine has already been built. Scientists, however, are still working on how to make it as efficient as possible, like in the Back to the Future movies.

Is it possible to go in the future?

While it’s not possible (yet) to travel to the future fast than the rate at which we’re doing it now, it is possible to speed up the passage of time. But, it only happens in small increments of time. And, it has only happened (so far) to very few people who have traveled off Earth’s surface.
