Is there a chance that there could be another solar system in our universe explain your answer?

Our planetary system is the only one officially called “solar system,” but astronomers have discovered more than 3,200 other stars with planets orbiting them in our galaxy. That’s just how many we’ve found so far. There are likely to be many more planetary systems out there waiting to be discovered!

What makes Planet Earth different from the other planets in the solar system?

Earth is one special planet. It has liquid water, plate tectonics, and an atmosphere that shelters it from the worst of the sun’s rays. The fact that Earth hosts not just life, but intelligent life, makes it doubly unique.

Is the universe a closed system?

The universe itself is a closed system, so the total amount of energy in existence has always been the same. The forms that energy takes, however, are constantly changing. The sum of these is called mechanical energy. The heat in a hot object is the mechanical energy of its atoms and molecules in motion.

What is one example of a closed system on earth?

A closed system allows only energy transfer but no transfer of mass. Example: a cup of coffee with a lid on it, or a simple water bottle.

How much of the universe have we not explored?

To date, scientists have explored about 4 percent of the visible universe. That’s made up of planets, stars and galaxies that astronomers can see. Yet, there’s a vast part – the other 96 percent – that scientists cannot see.

Is the only place in the universe that can support?

Earth is the only planet known to support life.

What would happen without the moon?

It is the pull of the Moon’s gravity on the Earth that holds our planet in place. Without the Moon stabilising our tilt, it is possible that the Earth’s tilt could vary wildly. It would move from no tilt (which means no seasons) to a large tilt (which means extreme weather and even ice ages).

What would happen if the Earth doesn’t have a 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 was the universe like after the Big Bang?

As space expanded, the universe cooled and matter formed. One second after the Big Bang, the universe was filled with neutrons, protons, electrons, anti-electrons, photons and neutrinos. Related: What Is Big Bang Theory?

How many times has the universe doubled in size?

During this period, the universe doubled in size at least 90 times, going from subatomic-sized to golf-ball-sized almost instantaneously. The work that goes into understanding the expanding universe comes from a combination of theoretical physics and direct observations by astronomers.

Will the universe eventually stop expanding?

The universe will eventually stop expanding and start collapsing in on itself, the so-called “Big Crunch.” If the density of the universe is less than this critical density, then the geometry of space is ” open ” and “negatively curved” like the surface of a saddle.

Is the universe accelerating or slowing down?

Then, in 1998, the Hubble Space Telescope’s observations of very distant supernovae revealed that a long time ago, the universe was expanding more slowly than it is today. In other words, the expansion of the universe was not slowing due to gravity, but instead inexplicably was accelerating.
