First, any object with mass (which includes you and me) cannot actually travel at the
speed of light. But you can get very close, in principle. However, assuming you were
moving very, very close to the speed of light, the time you experienced on board your
ship would be exceedingly short. From the perspective of a photon itself, the trip time is
exactly zero.
The theory of Special Relativity gives us a way to calculate the trip time, and the equation
includes a multiplier called the Lorentz Factor, which comes out to zero for the velocity of light.
==========================================
If you and your brother are both wearing wrist watches, and you go flying past him ... the
speed doesn't matter ... and as you pass him you both look at each others' watches, then
you'll say that your brother's watch is running slow, and your brother will say that YOUR
watch is running slow. You'll both be correct, and the faster you fly past him, the slower
each of you will see the other's watch running.
If it were possible for you to sail past him at the speed of light, then he would say that
your watch has stopped, and you would say that HIS watch has stopped. Just as at
any other speed, you would both be correct.
I know it doesn't make sense, but it happens to be true. It's been observed thousands of
times over the past hundred years or so. And a correction for it is built into the GPS system,
to correct the clocks for the speed of the satellites. Otherwise GPS would give flaky and
wrong results.

What is atmosphere presure and what causes it?
Atmospheric pressure is the weight of the air above a specific point, exerted by the mass of the atmosphere surrounding the Earth. It is primarily caused by the gravitational pull of the Earth, which holds air molecules close to the surface. As altitude increases, atmospheric pressure decreases because there are fewer air molecules above to exert pressure. This pressure is typically measured in units like pascals (Pa) or millibars (mb).
When the SUN will stop rotating what will happened?
If the Sun were to stop rotating, its magnetic field would weaken over time and the Sun's surface would become less active with fewer sunspots and solar flares. This could potentially have effects on Earth's climate and space weather, but it would not cause the Sun to go out or have an immediate impact on life on Earth.
Why do you think earths surface has fewer craters than the surface than moon does?
Basically, the atmosphere protects the earth to a great degree and the geological process always going on in and on the earth cover and change many crater sites.
What statement best explains why the moon has more craters than earth?
The moon has more craters than Earth primarily because it lacks a significant atmosphere, which means there is no weathering or erosion to diminish the visibility of impact sites. Additionally, the moon has no active geological processes, like plate tectonics or volcanic activity, that could reshape its surface and erase craters over time. In contrast, Earth's atmosphere, water, and geological activity continuously alter its surface, leading to fewer visible craters.
Does the moon have more craters than earth?
Yes, the moon has more craters than Earth. This is because the moon lacks an atmosphere to protect its surface from impacting rocks and debris, whereas Earth's atmosphere helps to burn up most objects before they reach the surface.
Are there more or fewer than one million minutes a year?
Fewer... There are 525,600 minutes in a 365 day year.
Which planet has fewer hours in a day than Earth?
Four planets hold this distinction: Jupiter (9 hours, 55 minutes) Saturn (10 hours, 33 minutes) Uranus (17 hours, 14 minutes) Neptune (16 hours, 6 minutes)
Which plant has fewer satellites earth or Uranus?
i meant planet Earth has fewer because Earth has only 1 satellite and Uranus has 27 satellites.
What are planets good for?
LIFE. Also that many fewer asteroids floating around that could slam into earth and end all life.
Can You give me a sentence using fewer and less?
If there were fewer of us, I could speak less.
What are the changes when you go through the atmosphere?
Although there are many gas molecules that surround you on Earth,there are fewer and fewer gas molecules in the air as you move away from Earth's surface. so, as altitude increases, air pressure decreases.
Can only be measured in 3 dimensions?
No, some properties can be measured in fewer than 3 dimensions. For example, temperature is a property that can be measured in one dimension, length is a property that can be measured in one dimension, and area is a property that can be measured in two dimensions.
What is the difference between fever and less?
"Fewer" is used when referring to countable items or things that can be quantified individually, like "fewer apples." "Less" is used when referring to things that cannot be counted or are measured as a whole, like "less sugar." So, you would say "fewer cars" but "less traffic."
Why temperature falls as you go higher?
the earth gives off much heat. as you ascend higher into the atmosphere, there is less heat from the earth, and fewer UV.
What is the difference between fewer and less?
The terms "fewer" and "less" are often confused, but they are used differently based on what they describe. Here’s a clear breakdown of the difference: Fewer Usage: "Fewer" is used with countable nouns—things that you can count individually. Examples: "There are fewer apples in this basket than in that one." (Apples are countable.) "She has fewer books than he does." (Books are countable.) "We need fewer chairs for the meeting." (Chairs are countable.) Less Usage: "Less" is used with uncountable nouns—things that cannot be counted individually and are typically measured in terms of volume, amount, or degree. Examples: "There is less water in the glass." (Water is uncountable.) "She has less time to complete the project." (Time is uncountable.) "We need less sugar in the recipe." (Sugar is uncountable.) Summary Fewer: Used with things that can be counted (e.g., apples, chairs, books). Less: Used with things that cannot be counted individually and are measured in bulk or degree (e.g., water, time, sugar). Examples in Sentences Fewer: "There are fewer students in the class this semester." Less: "There is less noise in the library than in the cafeteria." Using "fewer" for countable nouns and "less" for uncountable nouns helps ensure clear and accurate communication.
