The fasted "known" speed in the universe is the expansion of the universe itself, at about 74km/s per 3m lightyears. That is incredibly fast. The fastest obseved would be light at of course, lightspeed, or rougly 300,000,000m/s.
In a vacuum, light and all forms of electromagnetic energy travels at "c", which is 3 x 108 m/s. The discovery that this was the absolute speed limit independent of the observer is one of the core principles of relativity.

it was Helios 2 space probe reached 252,792 km/h, the fastest man-made object ever travelled.

Australia's fastest animal is the Kangaroo. The fastest recorded speed of a Kangaroo is 70 km/h which is 25 km/h FASTER than the fastest recorded speed of Australia's flightless bird the Emu.
I mostly think it is human brain waves which has the capacity to aquire signals from any regions of the universe

The speed of light. 300,000 km/h, is the fastest speed of any object in the universe.
Tachyons are theorised to be the fastest particle in the universe their slowest speed being the speed of light. But until they are proven to exist, light is the fastest thing in the universe.
Speed is how fast something moves. Light is a form of energy carried by massless photons, these photons move at the speed of light, which is the fastest speed that anything in the universe can travel.

The fastest speed at which anything can move is the speed of light, about 300,000 km/sec.
The Fastest speed possible in the Universe is the speed of light in a vacuum exceeding 299,792,458 meters per second.
You yourself do not have a speed limit of any kind. Everything else in the universe has the maximum speed of: Your Speed + the Speed of Light. However it is impossible to determine your own speed because there is no stationary point of reference in the universe.
The fastest that anything can go is the speed of light in a vacuum.
It's the fastest speed anyone can prove exists. Any speeds in excess of light speed are still just theory. Some scientists believe it is the fastest speed that will ever be achievable.( a cosmic speed limit.)
No, never! it is disproved by Einstein
