Is it possible to travel faster than light?
Albert Einstein’s special theory of relativity famously dictates that no known object can travel faster than the speed of light in vacuum, which is 299,792 km/s.
Unlike objects within space–time, space–time itself can bend, expand or warp at any speed..

What galaxies are closest to the Milky Way?
The Andromeda galaxy is the closest big galaxy to our Milky Way. At 2.5 million light-years, it’s the most distant thing you can see with the eye alone.
What is a dead galaxy?
MACS 2129-1 is what’s known as a “dead galaxy,” because stars no longer form there. … Scientists believed that galaxies of this sort had formed by merging with smaller galaxies over time, but MACS 2129-1’s stars didn’t form from these sort of explosive mergers; they formed early on, in the disk of the original galaxy.
What is the most dangerous thing in the universe?
Why black holes are the scariest things in the universe. For one, falling into a black hole is easily the worst way to die. Halloween is a time to be haunted by ghosts, goblins and ghouls, but nothing in the universe is scarier than a black hole.
What is the most powerful thing in the universe?
Quasars inhabit the centers of active galaxies and are among the most luminous, powerful, and energetic objects known in the universe, emitting up to a thousand times the energy output of the Milky Way, which contains 200–400 billion stars.
What is the fastest we can travel in space?
By 2024, it’s projected to reach a maximum speed of 430,000 mph (692,000 km/h). As of the 27th of September 2020, the Parker Solar Probe has already accelerated to a speed of 289,927 mph (466,592 km/h) relative to the Sun, officially becoming the fastest spacecraft to date.

Is there another galaxy like ours?
The Milky Way galaxy is in the Local Group, a neighborhood of about 30 galaxies. Our nearest major neighboring galaxy is called Andromeda.
How long would it take us to get to the Andromeda Galaxy?
2.5 million yearsHow long would it take to get to the Andromeda Galaxy? Forget it! Although it may be one of the closest galaxies to our own, since the Andromeda Galaxy is 2.5 million light years distant it would take 2.5 million years to get there if (and it’s a huge ‘if’) we could travel at the speed of light.
Can humans travel to another galaxy?
The technology required to travel between galaxies is far beyond humanity’s present capabilities, and currently only the subject of speculation, hypothesis, and science fiction. However, theoretically speaking, there is nothing to conclusively indicate that intergalactic travel is impossible.
Is the Milky Way moving?
The Milky Way as a whole is moving at a velocity of approximately 600 km per second with respect to extragalactic frames of reference. The oldest stars in the Milky Way are nearly as old as the Universe itself and thus probably formed shortly after the Dark Ages of the Big Bang.
How fast is the Milky Way moving towards Andromeda?
about 110 kilometres per secondThe Andromeda Galaxy is approaching the Milky Way at about 110 kilometres per second (68 mi/s) as indicated by blueshift.
What is the biggest galaxy in the universe?
IC 1101Largest galaxy: IC 1101 Our Milky Way galaxy is around 100,000 light-years across, but that’s fairly average for a spiral galaxy. In comparison, the largest known galaxy, called IC 1101, is 50 times larger and about 2,000 times more massive than our galactic home.
What is the most beautiful galaxy?

What does galaxy look like?
Some galaxies are spiral-shaped like ours. They have curved arms that make it look like a pinwheel. Other galaxies are smooth and oval shaped. … The light that we see from each of these galaxies comes from the stars inside it.
Is traveling through a wormhole possible?
Physicists have worked out a way that it might be feasible to send someone through a wormhole. Wormholes are tunnels between two black holes that connect distant regions of space-time, and normally it would be impossible to pass something through them, but factoring in an extra dimension might make it possible.
How long before the Milky Way collides with Andromeda?
Previous simulations have suggested that Andromeda and the Milky Way are scheduled for a head-on collision in about 4 billion to 5 billion years. But the new study estimates that the two star groups will swoop closely past each other about 4.3 billion years from now and then fully merge about 6 billion years later.
