Can you have gravity without time?

Yes, time exists without gravity! In the Minkowski spacetime of Special Relativity there is time but no gravity. Did you learn about Lorentz transformations and kinematic time dilation? They have nothing to do with gravity.

Are gravity and time the same thing?

Einstein described Gravitational Time Dilation in his general theory of relativity: "Clocks that are far from massive bodies run faster than clocks close to massive bodies." That means time passes slower wherever gravity is the strongest, so we know that gravity affects time.

Do you age slower in space?

Scientists have recently observed for the first time that, on an epigenetic level, astronauts age more slowly during long-term simulated space travel than they would have if their feet had been planted on Planet Earth.

How is 1 hour in space equal to 7 years on Earth?

The first planet they land on is close to a supermassive black hole, dubbed Gargantuan, whose gravitational pull causes massive waves on the planet that toss their spacecraft about. Its proximity to the black hole also causes an extreme time dilation, where one hour on the distant planet equals 7 years on Earth.

Does gravity slow time?

Gravity is not just a force.

This effect measures the amount of time that has elapsed between two events by observers at different distances from a gravitational mass. In other words, time runs slower wherever gravity is strongest, and this is because gravity curves space-time.

The REAL source of Gravity might SURPRISE you...

What created gravity?

Earth's gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body.

Can a wormhole exist?

In the early days of research on black holes, before they even had that name, physicists did not yet know if these bizarre objects existed in the real world.

Can time be bent?

So to answer your question, time does not literally "bend". A massive object modifies the proper time interval around it such that an outside observer would see objects near the mass experience less time and spacetime intervals would have their spatial components modified accordingly.

How many dimensions are there?

The world as we know it has three dimensions of space—length, width and depth—and one dimension of time. But there's the mind-bending possibility that many more dimensions exist out there. According to string theory, one of the leading physics model of the last half century, the universe operates with 10 dimensions.

What did Einstein say about wormholes?

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.

Does light have gravity?

Light has momentum and energy, so it is a source of gravity.

Why are we not upside down in Australia?

Remember that the Earth is a sphere, like a giant ball: so there is no "up" or "down", since a sphere is symmetric. That is, it looks the same no matter what way you look at it. So, people in Australia have just as much right to call themselves "up" as people in the Northern Hemisphere do!

Can we create gravity?

Creating artificial gravity

Fortunately, there is more than one form of acceleration — and by using centrifugal force we can generate something equivalent to gravity on Earth. One possible way of creating artificial gravity in space is by utilizing a technology called an O'Neill cylinder.

Does time stop in a black hole?

Time does stop at the event horizon of a black hole, but only as seen by someone outside the black hole. This is because any physical signal will get infinitely redshifted at the event horizon, thus never reaching the outside observer. Someone falling into a black hole, however, would not see time stop.

Is time Travelling possible?

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. And there are important reasons why we need to understand this real-world form of time travel.

Does time move faster as you age?

As we get older the rate of new experiences lessens compared with youth, when almost everything is new. That leads to a sense of the days being longer but time passing much more quickly overall.

Why don't we feel the Earth spinning?

Since the Earth rotates at a near-constant speed (that is, it doesn't speed up or slow down in any way noticeable to us), we simply spin with it and don't feel a thing.

What country is at the bottom of the Earth?

Amazing Antarctica

Antarctica is a place of extremes. It's the southernmost continent and hosts the coldest temperature ever directly recorded on Earth's surface — a bone-chilling minus 128.6 degrees Fahrenheit (minus 89.2 degrees Celsius) logged at Russia's Vostok research station.

Do black holes have gravity?

A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.

Why are black holes black?

A black hole have such strong gravity that nothing, not even light, can escape it. That's why black holes are black.

Is it possible to bend light?

But now researchers have shown that light can also travel in a curve, without any external influence. The effect is actually an optical illusion, although the researchers say it could have practical uses such as moving objects with light from afar. It's well known that light bends.

Can Earth become a black hole?

Despite their abundance, there is no reason to panic: black holes will not devour Earth nor the Universe. It is incredibly unlikely that Earth would ever fall into a black hole. This is because, at a distance, their gravitational pull is no more compelling than a star of the same mass.

Can a human survive a wormhole?

Humans could survive a trip through a wormhole, but there's a catch. There are drawbacks to this method — namely, such wormholes would be only microscopic, which means even the most hardcore exercise routine wouldn't make humans thin enough for the trip.
