What is the fastest moving object ever detected (relative to Earth), and how fast was it going?
I am not sure, but likely it is likely GN-z11.[1]This is the most distant galaxy detected. According to the standard cosmological model GN-z11 is moving away from us at over 2.2 times the speed of light…Now that is fast!At the suggestion of David P. Chassin, I’ve decided to add in a few links to describe different types of velocities.Basically the absolute value of “c” is only true locally under general relativity. Even then you need to use Geodesics to be completely accurate… Space-time itself has a motion associated with it. The type that is giving us such a huge value for GN-z11 is known as Recessional velocity.In the end though, velocity is just velocity. If it is local you can apply special relativity. If you are dealing with something in a different inertial reference frame, you need to also apply the relative velocity of that internal reference frame.You can imagine the flow of space, like the surface of river. The water moves. Light is the waves on the surface. The speed of the sound waves on the water is always constant relative to the water’s motion. Likewise, the speed of light is always constant relative to the motion of space. When we say motion is local, that means you are comparing the motion for objects where the difference in the motion of space is negligible..Because of the relative motion of space, it is possible to observe velocities faster than light (relative to us) for very distant objects, and objects passing near a black hole (due to the hull effect).Wormholes, if they exist are also an example of moving space. In this case though it is better to think of wormholes as a moving walkway, as you can only get on at the entrance and off at the exit.Footnotes[1] List of the most distant astronomical objects - Wikipedia
What is the biggest known celestial body in the universe?
A celestial body refers to a single, tightly bound contiguous entity, meaning objects like an asteroid, a planet, a moon, a star, or a black hole. For an elaborate list of celestial bodies, have a look here: Categories of celestial bodies and objects by locationThe biggest celestial body then is a supermassive black hole. The largest known black hole is S5 0014+81, which has a mass of 40 billion M☉ (solar masses). It is thus relatively close to the theoretical upper bound for the mass that a black hole can acquire through the conventional accretion disc method[1]. At 40 billion M☉, S5 0014+81 has a Schwarzschild radius of 790.0791 AU, or a diameter of 236.3883 billion km / 146.8849 billion mi. The Schwarzschild radius is the region beyond which the escape velocity exceeds the speed of light, and so no light reflects or escapes.Below is a comparison of the size of this black hole and our Solar System, with a conservative estimate for the size of the Solar System in yellow, and the minimum and maximum distance to the termination shock (the point where the Sun’s solar wind collides with the interstellar medium) in orange and blue.S5 0014+81 is thus 19.75, 10.53 or 8.78 times larger than our Solar System depending on which size estimate you take.Some would say a black hole is a region of warped spacetime and thus is not defined as an object but an event. Although this doesn't undermine the notion of a body, the Schwarzschild radius is one of influence rather than genuine size. So perhaps we ought to look at stars instead.The largest known star is UY Scuti, with a radius of approximately 1708 R☉. With S5 0014+81’s Schwarzschild radius of 790.0791 AU, it has a solar radius of 169,892.4 R☉. That means that UY Scuti is slightly over 1% the size of S5 0014+81.Below are the six largest known stars—including the Sun for reference—with UY Scuti at the bottom. If UY Scuti replaced our Sun, it would extend out to 76.42% of the way to the orbit of Jupiter.VY Canis Majoris, V354 Cephei, Westerlund 1-26, RW Cephei, WOH G64, UY ScutiIf you want to know what the largest object in the universe is, have a look at the following answer:Martin Silvertant’s answer to What is the largest object in the universe?Footnotes[1] [1511.08502] How Big Can a Black Hole Grow?
1st question: Is there design involved in the universE?
1st question: Is there design involved in the universE? as in, the way things work in this universe? the way the different laws compliment each other? 2nd question: if there is design in the universe, shouldn't there be a designer behind the design of the universe? anything that has design will have a designer right?
What is the fastest moving object (with mass) in the universe (observed and measured) and what is this speed?
I'm going to read the question with a few additions:What is the fastest object ever recorded, with respect to the Earth? There we go. Much better!Ok, since we want "objects", photons are out the window (that would be cheating anyway as they have no choice but to travel at [math] c [/math].)Ok fastest large scale object: by using Hubble's logic, the fastest Galaxies are those which are farthest away - the farthest confirmed Galaxy is MACS0647-JD, which has a redshift of 10.6 - which gives a velocity relative to Earth of 0.98c. I feel pretty confident in asserting that this is the fastest macro-scale object ever observed from Earth.Ok, what about micro-scale objects? The LHC accelerates things to about 0.999999991c about [math] 10^{-7} c [/math] away from c.However, compared to what is generated in particle cascades in our own atmosphere, that is puny! The fastest particle ever observed was the Oh-My-God! Particle - so named because that's what the researchers said when they saw it!This was a single particle (most likely a proton) travelling above Utah in 1991. It was moving at 0.9999999999999999999999951c. Whilst that doesn't sound much faster than the LHC, due to the "funky" nature of relativity, it contained more than a billion times more energy than a proton travelling at the same speed as the LHC's particles.This single, solitary proton contained 51 joules of kinetic energy, about the same as a baseball being pitched. In a single proton.Oh my god indeed!So, fastest macro-object is MACS0647-JD, travelling at 0.98c, and the fastest ever recorded object, in the history of science is the Oh-My-God! Particle, which is moving as close to c as to make no difference!
Which is the coldest planet in our solar system?
Being more than a billion more miles away from the Sun and receiving only about 40% of the solar radiation received by Uranus, you'd think Neptune would be much colder than Uranus. Scientists have been surprised to learn, though, that Uranus reaches colder temperatures despite the fact that Neptune, on average, is colder than Uranus.For example, Neptune's average temperature is approximately -350º F. Despite being a billion miles closer to the Sun, the average temperature of Uranus is approximately -325º F. Even though Uranus is usually slightly warmer than Neptune, it does reach the coldest temperatures of any planet. The coldest temperature ever recorded for Uranus was -371º F!Scientists aren't completely sure why Uranus reaches such cold temperatures despite being so much closer to the Sun than Neptune. Some speculate that it might have something to do with the planet's odd orientation.Uranus seems to have been knocked on its side, perhaps by a massiveimpact way back when the Solar System was first forming. Scientists think the strange tilt of Uranus could cause heat from its core to spill out into space. Scientists also suspect that Uranus has a very active atmosphere that causes it to lose heat. By way of comparison, scientists think Neptune's atmosphere helps to retain the heat from its hot core, leading to warmer temperatures than would otherwise be expected.
In the solar system which planet rotates faster on its axis?
Jupiter is the fastest spinning planet of our solar sytem. It’s rotation speed is about 43,000 kilometres/hour (it is the rotation speed of it’s equator) which is about 25.3 times faster than the rotation speed of Earth (which is about 1700km/h). Jupiter’s equator rotates a bit faster than it’s polar regions. The length of one day of jupiter is 9 hours and 50 minutes close to the equator. Jupiter has the shortest days of all the planets in the Solar System.IMAGE SOURCE- Jupiter - WikipediaBut if you talk about entire universe, then there is only one exoplanet whose speed of rotation has been measured by scientist till now. That planet is Beta Pictoris b, a gassy planet which rotates at a speed of breakneck 90,000 km/h. It’s one day lasts for only 8 hours. It beats all planets of our solar system in this aspect.
