Scientists may never fully answer whether there is life beyond Earth due to the vastness of the universe, which poses significant challenges in exploration and observation. The limitations of current technology and the immense distances involved make it difficult to detect extraterrestrial life, especially if it exists in forms or environments we do not yet understand. Additionally, life's existence may be rare or transient, complicating our search for evidence. Finally, philosophical and methodological questions about what constitutes "life" can further hinder definitive answers.
What else can I help you with?
Earth gravity reach beyond the atmosphere?
Oh yeah! It's why the moon - way out of our atmosphere - continues to circle around us. Earth's gravity keeps it close. In fact, even at 17 moon distances away from the Earth, gravity still reaches. Granted, it's 1/millionth of what it is on the surface of the Earth, but the gravitational pull between two objects in fact, never ends, it just gets infinitesimally smaller.
How many earths is it in the universe?
It is currently unknown how many Earth-like planets exist in the universe. Scientists have discovered thousands of exoplanets, some of which may have conditions favorable for life, but the exact number of Earth-like planets is still uncertain due to the vastness of the universe.
Can you use universe in a sentence?
The universe is a vast and mysterious place that never ceases to amaze astronomers and scientists.
Is it correct to say that satellites stay in orbit rather than falling to Earth because they are beyond the pull of earth's gravity?
No! They are in orbit because of earth's gravity. If they were beyond the pull of earth's gravity, they would fly off and never return. Everything that is in orbit around earth is falling towards earth. Their orbital velocity is great enough so that it compensates for the downward pull.When you throw a ball it falls in a curve. Throw it harder and the ball will fall farther away but will still fall along a curve. Throw it as hard as possible and it will still follow a curved path and eventually land. Gravity causes it to fall along a curve. Now imagine throwing a ball SO HARD that it returns to you from the opposite direction. Gravity has been pulling on it causing it to move along a curved path, but its velocity sends it around earth in an orbit.
What year might we not be able to live on our planet anymore?
Hopefully that will never happen. Hopefully people will take steps to prevent that from happening. The earth has an amazing capability to cleanse itself, unless there is some terrible catastrophe, like a meteor smashing into earth humans should always be able to inhabit the earth as evolution causes ones to adapt to the environment.
Why will scientists never know about all the species on earth?
Most organisms never became fossils
What the temp of the center of the earth?
Scientists can never be sure of the exact temperatures at the center of the Earth, because we can not directly travel to the center of the Earth. Some scientists believe it is around 12,500 degrees Fahrenheit.
What is the temp of center of earth?

Can you go and see black holes with a space shuttle?
No. The spac shuttle does not go beyond low Earth orbit. To see a black hole would require interstellar travel, which is not possible with current technology and might never be possible.
What does to infinity and beyond mean?
Beyond the never ending
How do you know about the inside of the earth if you have never seen it?
You guess. Simple as that. You might also watch the documentary "Journey to the center of the earth"
Why do people have quizzes on zombie attacks when they're not real?
You never know what might pop up from the ground, there have been some zombie sighting. like in 2002 in virgin islands. so you never know what scientists might conduct
How do you know that the earth is in layers?
Scientists have determined the layers of the Earth by studying seismic waves from earthquakes. These waves travel through the Earth at different speeds and provide information about the density and composition of the different layers beneath the surface. By analyzing this data, scientists have been able to deduce the Earth's structure and layers.
Have werwolves ever been sighted?
No. Werewolves don't exist beyond the movies, TV, and stories. They are NOT real and will never been seen on earth.
Has Sally Ride been to the moon?
No. Sally Ride has been in low Earth orbit, but never beyond that. No woman has ever been to the moon.
How did the earlier scientists and their contributions directly affect the discoveries of later scientists?
Since glass was invented, the scientists were able to create the microscope. If this was never invented, the scientists would never have been able to discover cells.
