Is time an illusion or real?
There is no certain answer for this. one can say time is real as The currently accepted view of physics is that time is as real as space. Time is sometimes thought of as 'just' the fourth dimension, but it seems as though it is somehow different from the three dimensions of space. For a start, it apRead more
There is no certain answer for this.
See lessone can say time is real as The currently accepted view of physics is that time is as real as space. Time is sometimes thought of as ‘just’ the fourth dimension, but it seems as though it is somehow different from the three dimensions of space. For a start, it appears to flow in only one direction.
Other even Einstein said that it’s an illusion.Albert Einstein, shared this view, writing, “People like us who believe in physics know that the distinction between past, present, and future is only a stubbornly persistent illusion.” In other words, time is an illusion
What is the oldest thing in the universe?
According to the best cosmic evidence we’ve been able to assemble, we can precisely determine the age of the Universe to be 13.8 billion years since the start of the hot Big Bang, with an uncertainty of just ~1%. And yet, we know how stars work, and astronomers have estimated the age of the MethuselRead more
According to the best cosmic evidence we’ve been able to assemble, we can precisely determine the age of the Universe to be 13.8 billion years since the start of the hot Big Bang, with an uncertainty of just ~1%. And yet, we know how stars work, and astronomers have estimated the age of the Methuselah star, found right here in the Milky Way, to be 14.5 billion years old: significantly older than the cosmos itself. Clearly, you can’t have a star within the Universe that’s older than the Universe itself. But what is it that’s wrong: our estimates for the star’s age, the Universe’s age, or something else entirely?

Near a black hole, the slowing of time is extreme. From the viewpoint of an observer outside the black hole, time stops. For example, an object falling into the hole would appear frozen in time at the edge of the hole.

Caltech researchers have found mathematical evidence suggesting there may be a “Planet X” deep in the solar system. This hypothetical Neptune-sized planet orbits our Sun in a highly elongated orbit far beyond Pluto. The object, which the researchers have nicknamed “Planet Nine,” could have a mass about 10 times that of Earth and orbit about 20 times farther from the Sun on average than Neptune. It may take between 10,000 and 20,000 Earth years to make one full orbit around the Sun.
The announcement does not mean there is a new planet in our solar system. The existence of this distant world is only theoretical at this point and no direct observation of the object nicknamed “Planet 9” have been made. The mathematical prediction of a planet could explain the unique orbits of some smaller objects in the Kuiper Belt, a distant region of icy debris that extends far beyond the orbit of Neptune. Astronomers are now searching for the predicted planet.
See lessCan we survive in black hole?
Within any black hole is the central point, the singularity, which has infinite gravity and where mass is compressed into an infinitely small point. There, it is game over. There's no surviving. And therefore the idea of traveling through time and space, via black hole or wormhole, don't really regiRead more

And therefore the idea of traveling through time and space, via black hole or wormhole, don’t really register in reality.
See lessHow many galaxies are there?
It is estimated that there are between 200 billion (2×1011) to 2 trillion galaxies in the observable universe. Most galaxies are 1,000 to 100,000 parsecs in diameter (approximately 3,000 to 300,000 light years) and are separated by distances in the order of millions of parsecs (or megaparsecs).

See lessHow much does 1 gram of dark matter cost?
One estimate suggests that the cost of producing a single gram of dark matter could be around $65.5 TRILLION. This is based on the idea that dark matter is made up of weakly interacting massive particles (WIMPs), which are thought to interact with normal matter only through gravity.

See lessWho discovered dark matter?
The first real evidence for dark matter came in 1933, when Caltech's Fritz Zwicky used the Mount Wilson Observatory to measure the visible mass of a cluster of galaxies and found that it was much too small to prevent the galaxies from escaping the gravitational pull of the cluster.

See lessdid India set up a dark matter lab?
India has set up a new underground lab to join the quest to detect dark matter. The Underground Science Laboratory, which cost $31,000, was inaugurated last month and is based at the country's oldest uranium mine at Jaduguda in central India.
