Why do planets have different time?
Heavy things like planets create a gravitational field that slows down time nearby. This means that a clock on a spaceship far away from any planet would move faster than a clock near Earth. This is different from time dilation explained by special relativity, which says that fast objects move more slowly through time.
Why are there different time zones and which countries on Earth have the same time of the day?
As the planet rotates, some places receive sunlight or darkness, resulting in day and night. As the Earth rotates into the sunlight, you’ll see the sunrise, whereas rotating out of the sunlight is where you see the sunset. The Earth’s rotation is the primary cause why countries follow different time zones.
Why cant it be 8pm at the same time across the world?
They want to do away with time zones completely, and put the entire world on universal time (UTC). Under their system, when it’s 9:00 in one place, it’s 9:00 everywhere on the planet, even if it’s morning in one place and evening in another. And the internet essentially runs on universal time.
Do different planets have different time?
We can write a paragraph about how long days last on other planets. On Mercury a day lasts 1,408 hours, and on Venus it lasts 5,832 hours. On Earth and Mars it’s very similar. Saturn takes 11 hours, Uranus takes 17 hours, and Neptune takes 16 hours.
How can 1 hour on a planet be 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.
Do you age faster in space?
Flying through outer space has dramatic effects on the body, and people in space experience aging at a faster rate than people on Earth. These studies showed that space alters gene function, function of the cell’s powerhouse (mitochondria), and the chemical balance in cells.
Why does Australia have different time zones?
Australia’s external territories observe different time zones. Standard time was introduced in the 1890s when all of the Australian colonies adopted it. Before the switch to standard time zones, each local city or town was free to determine its local time, called local mean time.
Why does America have different time zones?
American railroads maintained many different time zones during the late 1800s. Each train station set its own clock making it difficult to coordinate train schedules and confusing passengers. Every city in the United States used a different time standard so there were more than 300 local sun times to choose from.
Is London always UTC?
The United Kingdom uses Greenwich Mean Time or Western European Time (UTC) and British Summer Time or Western European Summer Time (UTC+01:00)….IANA time zone database.

What is UT1 time?
Universal Time 1
UT1 (Universal Time 1) measures the Earth’s rotation with respect to the distant stars (quasars, nowadays), scaled by a factor of (one mean solar day)/(one sidereal day), with small adjustments for polar motion. There are exactly 86400 UT1 seconds in a UT1 day.
