Are there infinite galaxies? Our universe is just a finite number of galaxies rushing away from each other inside this empty infinite space—like a solitary skyrocket exploding and sending out a doomed shower of sparks.” But many cosmologists say, no, there are an infinite number of galaxies in our infinite space.
Then, How do planets look through telescopes?
In a moderate telescope Venus and Mercury will reveal their phases (a crescent shape) and Venus can even show hints of cloud details with a right filter. Neptune and Uranus will look like small, featureless, bluish or greenish disks through any telescope.
Secondly, Can the universe end? Astronomers once thought the universe could collapse in a Big Crunch. Now most agree it will end with a Big Freeze. … Trillions of years in the future, long after Earth is destroyed, the universe will drift apart until galaxy and star formation ceases.
How cold is space?
Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that, at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit).
What is beyond the universe?
Scientists now know the universe is expanding, at an ever-increasing rate. … Defining this “beyond the universe” would imply that the universe has an edge. And that’s where things get tricky, because scientists aren’t certain if such a drop-off exists.
What can you see with a 100mm telescope?
What Can You Expect From 100mm Telescopes? (With Photos)

Can I see Pluto with a telescope?
Can I See Pluto With a Telescope? Yes, you can see Pluto but you’ll need a large aperture telescope! Pluto resides at the very edges of our solar system and shines only at a faint magnitude of 14.4. … The dwarf planet is 3,670 million miles away from the Sun and looks just like another faint star in your telescope.
Can you really see planets with a telescope?
Observing the planets through a telescope is a top bucket list experience for many. … A small telescope can reveal details on giant planets because of how much light they reflect. Medium and large telescopes will provide views of Venus, Mars, Jupiter, and Saturn, even in light-polluted areas.
Is Universe in a black hole?
The birth of our universe may have come from a black hole. Most experts agree that the universe started as an infinitely hot and dense point called a singularity. … It is, in fact, and some physicists say they could be one and the same: The singularity in every black hole might give birth to a baby universe.
Is time Travelling possible?
In Summary: Yes, time travel is indeed a real thing. But it’s not quite what you’ve probably seen in the movies. Under certain conditions, it is possible to experience time passing at a different rate than 1 second per second.
Is the Big Rip possible?
One grim possible outcome is a Big Rip, which would ultimately unravel all matter down to the atomic level—though not for billions of years or longer.
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 a virus survive in space?
As noted by BBC Science Focus, viruses can’t survive for long without viable host; most can live for hours in the air and days on indoor surfaces at room temperatures. And that’s under ideal conditions. Even the toughest, nastiest pathogen would find it problematic to stay alive in the freezing dark of space.
How cold is a black hole?
The black hole evaporates. The most massive black holes in the Universe, the supermassive black holes with millions of times the mass of the Sun will have a temperature of 1.4 x 10–14 Kelvin. That’s low. Almost absolute zero, but not quite.
Who created universe?
Many religious persons, including many scientists, hold that God created the universe and the various processes driving physical and biological evolution and that these processes then resulted in the creation of galaxies, our solar system, and life on Earth.
Is our universe in a black hole?
The birth of our universe may have come from a black hole. Most experts agree that the universe started as an infinitely hot and dense point called a singularity. … It is, in fact, and some physicists say they could be one and the same: The singularity in every black hole might give birth to a baby universe.
What is the big BNAG theory?
The big bang is how astronomers explain the way the universe began. It is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now—and it is still stretching!
What can you see with a 130mm telescope?
You will be able to see Moon, Jupiter, Mercury(looks like a star), Venus, Saturn pretty well. Mars would be disappointing a bit. Its too small. You will get 65x with a 10 mm.
How powerful does a telescope have to be to see the rings of Saturn?
The rings of Saturn should be visible in even the smallest telescope at 25x [magnified by 25 times]. A good 3-inch scope at 50x [magnified by 50 times] can show them as a separate structure detached on all sides from the ball of the planet.
What can you see with a 70mm telescope?
The colorful bands and belts of Jupiter, as well as its four major moons, and the rings of Saturn are clearly visible in a 70mm telescope. Mars, Venus and Mercury are visible in a small scope as well, but are extremely reluctant to give up any detail because of their overwhelming brightness.
How does Mars look through a telescope?
During favourable times, Mars appears as a very bright star tinged with red. … If you are observing without optical instruments, it is, of course, impossible to discern any details on Mars as you would with a refractor or a reflector telescope. In general, planets appear like stars to the unaided eye.
Is a 5 inch telescope good?
5-inch Telescopes offer exceptional resolution for their size. They can resolve double stars at . 91 arcseconds and can be magnified up to 254 times the human eye. 5″ Optical tubes also make exceptional light gatherers by allowing an observer to see 14.3 magnitude stars!
Can a wormhole exist?
In the early days of research on black holes, before they even had that name, physicists did not yet know if these bizarre objects existed in the real world. The original idea of a wormhole came from physicists Albert Einstein and Nathan Rosen. …
What is a white hole in space?
A white hole is a bizarre cosmic object which is intensely bright, and from which matter gushes rather than disappears. In other words, it’s the exact opposite of a black hole. But unlike black holes, there’s no consensus about whether white holes exist, or how they’d be formed.
What is Stephen Hawking’s black hole theory?
In 1971, Stephen Hawking proposed the area theorem, which set off a series of fundamental insights about black hole mechanics. The theorem predicts that the total area of a black hole’s event horizon — and all black holes in the universe, for that matter — should never decrease.
