What else can I help you with?
In 1964 Arno Penzia and Robert Wilson discovered that radiation bombards Earth from all directions in space Cosmologists reason that this radiation is cosmic background radiation left over from the?
A theory that states that the universe began with a tremendous explosion.
How was CMB radiation first discovered?
Completely by accident. Arno Penzias and Robert Wilson were scientists at Bell Laboratories who, in 1964, were seeking to find the cause of background noise in microwave signals bounced off telecommunication satellites. They found that the noise came from outer space (not the surface of the Earth), was a black-body spectrum, did not vary between day and night, and was completely isotropic. Puzzled, they strove vigorously to eliminate any possible cause (including pigeon feces in their antenna) other than microwaves from outer space. Eighteen years earlier, George Gamow had predicted that the Big Bang would result in just that kind of radiation. However, no astronomer wanted to bother to look for it until a group at Princeton University (almost NEXT DOOR to Bell Labs!!) began, in 1964, to work out how to do so. When Penzias and Wilson saw that what the Princeton scientists were looking for, exactly matched what they had just found, they realized they had made a huge discovery. Fourteen years later they got their Nobel Prize.
What is the transfer of energy through space?
Radiation
How is heat transferred through empty space?
Light energy, like from the sun.
What transfers thermal energy through space?
There are three mechanisms by which thermal energy (heat) is transferred through space: conduction, convection, and radiation.1Radiation is the transfer of heat energy through empty space. All objects with a temperature above absolute zero radiate energy at a rate equal to their emissivity multiplied by the rate at which energy would radiate from them if they were a black body. No medium is necessary for radiation to occur; radiation works even in and through a perfect vacuum. The energy from the Sun travels through the vacuum of space before warming the earth. Also, the only way that energy can leave earth is by being radiated to space.The transfer of thermal energy through space is called Radiation

A theory that states that the universe began with a tremendous explosion.
An approximate age for the universe can be deduced from?
Based on the mathematical calculations of Robert H. Dicke, Jim Peebles, and David Wilkinson (astrophysicists at Princeton University), if there had been a "big bang" explosion that created the universe, we ought to be able to detect reflected energy - sort of like "echoes" of the big bang - isotropically, or "from everywhere equally", around the cosmos. We also ought to be able to calculate the time since then by measuring the frequency of that reflected energy. In 1964, two scientists named Arno Penzias and Robert Wilson were trying to determine the cause of some background "static" noise in AT&T's microwave communications antennas. The background noise seemed to be isotropic, coming from every direction in space equally. When they all got together, they realized that Penzias and Wilson had discovered the exact sort of background radiation that Dicke, Peebles and Wilkinson had predicted - and that, further, the background radiation was the right frequency to date the "big bang" at about 14.5 billion years ago. Penzias and Wilson shared the Nobel Prize in Physics in 1978.

What did arno pezias and Robert Wilson discover?
They are very smart people that discovered something special about space
How is the sun reflecting it radiation into space?
The sun does not reflect its radiation into space.
Can radiation travel though space?
All types of radiation can travel through space.
What moves around empty space is it radiation or convection or conduction?
Empty space implies radiation.
How does the radiation takes place in space?
Radiation in space primarily comes from stars, including our Sun, which emit electromagnetic radiation across a range of wavelengths. Other sources of radiation in space include cosmic rays, which are high-energy particles originating from sources such as supernovae. Radiation in space can impact astronauts and spacecraft, which is why shielding and protective measures are important for space missions.
Was there acutally a bang to be heard in the big bang?
No because then it wouldn't have been a bang. The above information is actually incorrect, however is slightly correct in the respect that tecqnically a bang is a loud noise, the big bang should actually be called the big explosian, back to the main topic, the big "bang"would have been silent as space is a large vaccum and does not carry the waves needed to carry sound as an example we learnt in school last year that in space if two astronaughts microphones broke they would have to phsically touch helmets to communicate as the vaccum of space would not carry the waves between particle (like on earth)
When was the big bang theory discovered and by whom?
In 1924, Alexander Friedman was the first to note that the equations of General Relativity would allow a universe with space that was either shrinking or expanding, but not a static universe. He made no effort to say what our Universe was doing. In 1927, Jesuit priest Georges Lemaitre was the first to explicitly state that our Universe was expanding and that there was, in his words, "a day with no yesterday." He also suggested that present astronomical observations supported his idea. Einstein initially ridiculed Lemaitre's ideas, but Einstein later admitted he was wrong. In 1929, Edwin Hubbell showed that the space was, indeed, expanding; but this fact did not also prove that matter was once far more dense than it is today. Our Universe could simply have been creating matter for all eternity, keeping mass density about the same as space expands. The latter idea was championed by Fred Hoyle, who referred to Lemaitre's view as the "Big Bang" (in 1949) and his own as "Steady State." Big Bang Cosmology predicted an isotropic microwave radiation resembling a black body of temperature 3K; Steady State Cosmology didn't. When this microwave radiation was found in 1964 by Robert Wilson and Arno Penzias, BBC achieved near universal acceptance. Today, Steady State Cosmology borders on pseudo-science. So take your pick: Friedmann, Lemaitre, Hubbell, Hoyle, or Wilson & Penzias.
The primary method of energy transfer by which Earth loses energy to outer space is?
Radiation is the primary method by which Earth loses energy to outer space. Specifically, the Earth emits longwave infrared radiation into space, which carries away excess heat and helps maintain the planet's energy balance.
Which can travel through empty space out of insulator convection electomagnetic conduction or radiation?
Radiation can travel through empty space. The radiation in question is electromagnetic waves.
