What If Earth Was Bigger

What If Earth Was Bigger?

If Earth’s diameter were doubled to about 16 000 miles the planet’s mass would increase eight times and the force of gravity on the planet would be twice as strong. … If gravity were twice as strong bodies possessing the same construction and mass as our flora and fauna would weigh twice as much and would collapse.May 19 2011

What if Earth was 50% bigger?

That radius would be about 9680 kilometers (Earth is 6670 km). If our planet was 50% larger in diameter [while maintaining the same density] we would not be able to venture into space at least using rockets for transport. … The Moon’s escape velocity is a mere 21.3% of Earth’s.

What would happen if Earth was bigger than the sun?

If our world was as big as the Sun then like the water our soil would have to be spread out to cover a much larger space. … With the Earth as big as the Sun you’d pretty much lose the Moon either way. But if a planet has more mass it will also have a stronger gravitational pull.

What if Earth was 1.5 times bigger?

So with 1.5 times the volume and mass of Earth we would have about a 14.5% higher surface gravity 1.51.523 and a 14.5% higher orbital velocity √1.51.513. There should be no problem at all with our current rocket technology to get into orbit from the planet so long as its atmosphere isn’t any thicker than ours.

Is it possible for Earth to get bigger?

Earth isn’t getting bigger. It’s actually getting smaller! … Space around Earth is dusty it’s full of asteroid debris comet trails and ionized particles streaming away from the sun. And as our planet flies through that dust our gravity vacuums it up.

What if Earth had ring?

Earth’s hypothetical rings would differ in one key way from Saturn’s they wouldn’t have ice. Earth lies much closer to the sun than Saturn does so radiation from our star would cause any ice in Earth’s rings to sublime away. Still even if Earth’s rings were made of rock that might not mean they would look dark.

Can we breathe without gravity?

As long as the air around us is thick enough we can breathe regardless of gravity. On Earth gravity is what holds our atmosphere. When astronauts go into space they can breath because their space ships and space suits keep the air around them even though gravity is very weak.

What if the sun exploded?

The good news is that if the Sun were to explode – and it will eventually happen – it wouldn’t happen overnight. … During this process it will lose its outer layers to the cosmos leading to the creation of other stars and planets in the same way that the violent burst of the Big Bang created Earth.

What if Earth was a cube?

The top and the bottom faces would be polar while the remaing four sides would enjoy an equatorial climate. However if the Earth was a cube that rotated through its corners then each side would have a temperate climate you could say good bye to extreme temperatures and precipitation.

What if Earth stopped spinning?

At the Equator the earth’s rotational motion is at its fastest about a thousand miles an hour. If that motion suddenly stopped the momentum would send things flying eastward. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes.

Can the Earth lose gravity?

Over the next few billion years Earth’s gravity will change by tiny amounts because of several events. As the sun expands the oceans will boil off into space reducing the planet’s mass and therefore cutting the force of its gravity. But Earth’s core will also cool so the planet will experience thermal contraction.

What would happen if you fell into a black hole?

The fate of anyone falling into a black hole would be a painful “spaghettification ” an idea popularized by Stephen Hawking in his book “A Brief History of Time.” In spaghettification the intense gravity of the black hole would pull you apart separating your bones muscles sinews and even molecules.

What if Earth’s gravity doubled?

If Earth’s diameter were doubled to about 16 000 miles the planet’s mass would increase eight times and the force of gravity on the planet would be twice as strong. … If gravity were twice as strong bodies possessing the same construction and mass as our flora and fauna would weigh twice as much and would collapse.

Is Earth getting closer to the sun?

We are not getting closer to the sun but scientists have shown that the distance between the sun and the Earth is changing. … The sun’s weaker gravity as it loses mass causes the Earth to slowly move away from it. The movement away from the sun is microscopic (about 15 cm each year).

How old is the Earth?

4.543 billion years

Is Sun getting bigger?

The Sun has increased in size by around 20% since its formation around 4.5 billion years ago. It will continue slowly increasing in size until about 5 or 6 billion years in the future when it will start changing much faster.

What if Earth had 2 moons?

If Earth had two moons it would be catastrophic. An extra moon would lead to larger tides and wipe out major cities like New York and Singapore. The extra pull of the moons would also slow down the Earth’s rotation causing the day to get longer.

Did the Earth have 2 moons?

Slow collision between lunar companions could solve moon mystery. Earth may have once had two moons but one was destroyed in a slow-motion collision that left our current lunar orb lumpier on one side than the other scientists say.

What if Earth had 100 moons?

Has anyone died in space?

A total of 18 people have lost their lives either while in space or in preparation for a space mission in four separate incidents. Given the risks involved in space flight this number is surprisingly low. … The remaining four fatalities during spaceflight were all cosmonauts from the Soviet Union.

Are there dead bodies in space?

Remains are generally not scattered in space so as not to contribute to space debris. Remains are sealed until the spacecraft burns up upon re-entry into the Earth’s atmosphere or they reach their extraterrestrial destinations.

How long is 1 hour in space?

Answer: That number times 1 hour is 0.0026 seconds. So a person at that deep space location would have a clock that would run for one hour while that person calculated that our clock ran for 59 minutes 59.9974 seconds.

Can we live without the Sun?

Without the Sun’s rays all photosynthesis on Earth would stop. … While some inventive humans might be able to survive on a Sun-less Earth for several days months or even years life without the Sun would eventually prove to be impossible to maintain on Earth.

How was Earth created?

When the solar system settled into its current layout about 4.5 billion years ago Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets Earth has a central core a rocky mantle and a solid crust.

How long will the Earth last?

By that point all life on Earth will be extinct. The most probable fate of the planet is absorption by the Sun in about 7.5 billion years after the star has entered the red giant phase and expanded beyond the planet’s current orbit.

What would happen if Earth was donut shaped?

The overall climate on donut Earth would be similar to what we currently have on our round Earth. It would be colder in the polar regions and warmer at the equator. But the weather would be a little more extreme and could even make some parts of the planet inhospitable due to storms and hurricanes.

Can a donut shaped planet exist?

A donut planet also known as a toroid planet is a theoretical type of planet that resembles a donut rather than a typical sphere. While a donut planet is extremely unlikely to naturally exist anywhere in the universe it is actually possible for such a planet to exist.

What would happen if the Earth split in half?

As the Earth is methodically sliced in half its mantle and core would be exposed to the vacuum of space causing massive earthquakes that would be felt everywhere on the planet. … At this stage almost all of the planet’s human inhabitants — 7.5 billion people — would be without electricity.

What would happen if the moon exploded?

If the moon exploded the night sky would change. We would see more stars in the sky but we would also see more meteors and experience more meteorites. The position of the Earth in space would change and temperatures and seasons would dramatically alter and our ocean tides would be much weaker.

What would happen if there was no moon?

The moon influences life as we know it on Earth. It influences our oceans weather and the hours in our days. Without the moon tides would fall nights would be darker seasons would change and the length of our days would alter.

What does the Earth complete in 24 hours?

Earth’s rotation or Earth’s spin is the rotation of planet Earth around its own axis as well as changes in the orientation of the rotation axis in space. … Earth rotates once in about 24 hours with respect to the Sun but once every 23 hours 56 minutes and 4 seconds with respect to other distant stars (see below).

What if we lost gravity for 5 seconds?

In truth it’s not humility but gravity – the natural phenomenon pulling matter together – that keeps humans and other objects grounded. If our planet were to lose gravity for even five seconds it would spell the end of life on Earth as we know it. … Without gravity humans and other objects would become weightless.

What if gravity stopped for 1 second?

When gravity disappears for 1 second the outwards force balanced by the gravity would be released causing a massive explosion. In other star systems with more immense stars and natural phenomena such as pulsars and and especially black holes the explosions and expansions would be greater.

Can we create gravity?

Artificial gravity can be created using a centripetal force. … In accordance with Newton’s Third Law the value of little g (the perceived “downward” acceleration) is equal in magnitude and opposite in direction to the centripetal acceleration.
