General Relativity states that space and time are fused and that nothing can travel faster than the speed of light . General relativity also describes how mass and energy warp spacetime – hefty objects like stars and black holes curve spacetime around them.
Is it scientifically possible to travel faster than light?
So-called “warp drives” have been proposed before, but often rely on theoretical systems that break the laws of physics. That’s because according to Einstein’s general theory of relativity, it’s physically impossible for anything to travel faster than the speed of light .
What is the fastest thing in the universe?
Laser beams travel at the speed of light , more than 670 million miles per hour, making them the fastest thing in the universe.
Is a black hole faster than light?
Supermassive black hole bigger than 7 billion Suns is spinning so fast that it’s close to breaking the laws of physics. Messier 87, star of the first image of the black hole , is spinning between 2.4 to 6.3 times faster than the speed of light .
Can anything travel faster than the speed of 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.
Do wormholes exist?
Physicists believe wormholes may have formed in the early universe from a foam of quantum particles popping in and out of existence. Some of these “primordial wormholes” may still be around today. ... They may even help us understand some of the deepest cosmic mysteries, such as whether our universe is the only one.
Is it possible to travel back in time?
General relativity. Time travel to the past is theoretically possible in certain general relativity spacetime geometries that permit traveling faster than the speed of light, such as cosmic strings, traversable wormholes, and Alcubierre drives.
What is faster light or sound?
The speed of light as it travels through air and space is much faster than that of sound ; it travels at 300 million meters per second or 273,400 miles per hour. Visible light can also travel through other things besides through air and through space. ... Speed of light in a vacuum and air = 300 million m/s or 273,400 mph.
What is the slowest car in history?
The slowest production car in existence is a coupe manufactured by Peel Engineering. It is called the Peel P50 . Peel offers both a petrol and electric version of the vehicle. Not only is it the slowest car in existence, but it is also the smallest (smaller than a Smart Car or Fiat), according to Guinness World Records.
How fast is the speed of dark?
Is there such a thing as the speed of dark? In a 2013 study, scientists determined that dark matter should have a speed of 54 meters per second , or 177 feet — slow compared to the speed of light.
Why can’t light escape a black hole?
Answer: Within the event horizon of a black hole space is curved to the point where all paths that light might take to exit the event horizon point back inside the event horizon . This is the reason why light cannot escape a black hole.
Will a black hole come to earth?
Scientists have discovered one of the smallest black holes on record – and the closest one to Earth found to date. ... Very few black holes of this mass have been found in the universe. This black hole is 1,500 light years away from Earth, still inside the Milky Way galaxy.
Why is travel through a wormhole impossible?
A Harvard physicist has shown that wormholes can exist: tunnels in curved space-time, connecting two distant places, through which travel is possible. ... “It takes longer to get through these wormholes than to go directly, so they are not very useful for space travel ,” Jafferis said.
Can a time machine be invented?
An Iranian scientist has claimed to have invented a ‘time machine’ that can predict the future of any individual with a 98 per cent accuracy. Serial inventor Ali Razeghi registered “The Aryayek Time Traveling Machine” with Iran’s state-run Centre for Strategic Inventions, The Telegraph reported.
What is the formula for time travel?
In fact, according to Albert Einstein’s famous equation, E = mc2 , time travel is possible, at least in one direction.
Why does time slow down at the speed of light?
The mathematics of Special Relativity tells us that as a reference frame moves at ever higher speeds, its space contracts ever smaller and its time becomes ever slower, relative to the stationary observer. ... This limiting behavior simply tells us that there is no valid reference frame at the speed of light.
